= Welcome to Video Dev Days 2019 =

The [[VideoLAN]] non-profit organization is happy to invite you to the multimedia open-source event of the fall!

For its eleventh edition, people from the VideoLAN and open source multimedia communities will meet in '''Tokyo''' to discuss and work on the future of the open-source multimedia community.

This is a very technical conference, focused on low-level multimedia.

== Who can come? ==

Literally every one is invited to VDD, we just need registration for legal reason ''(to enter the building)''.

This is a technical conference, focused on low-level multimedia, like codecs and their implementations like '''x264''' or '''dav1d''', frameworks like '''FFmpeg''' or '''Gstreamer''' or playback libraries like '''libVLC'''.

Things like Javascript video frameworks or ad-injection frameworks would be considered out of scope.

The price to enter is totally '''Free'''.

== Sponsorship for Japan ==

Since '''Japan''' is a bit further than the usual conferences, often in Europe, going to Japan is more expensive.

If you want [[VideoLAN]] to sponsor your trip, you should read the [[VDD19/Sponsor_Policy|Sponsorship Policy]].

== Traveling to Japan ==

You should consider staying a bit longer to '''Japan''', if you can afford a few extra days. Kyoto is amazing!

You should take care of your passport and, if applicable, your visa very quickly!

See the dedicated page: [[VDD19/Traveling_Advice|traveling advice for Japan]].

You might want to consider to '''offset your carbon footprint'''. 
For example: [https://co2.myclimate.org/en/flight_calculators/new MyClimate CO2 Calculator] or [https://www.carbonfootprint.com/carbonoffset.html CarboonFootPrint.com]

|}
'''NOTE''': VideoLAN does not refund taxi, car rental and public transport.

=== Rail pass ===
If you have a voucher for a rail pass, you should save it for before or after the conferencing days. JR passes are of limited within central Tokyo. They are valid for the ''Yamanote'' loop and the ''Chuo-Sobu'' east-west transverse train lines, as well as JR-operated buses, but not on the metro networks.

== Means of payment ==

VISA and MasterCard cards are '''not''' universally accepted in Japan.

=== Cash ===
You will need to withdraw cash from an ''international'' ATM (accepting VISA, MasterCard, AmEx, Discovery and UnionPay). You can find those:
* at arrivals in the airport terminal,
* at '''[https://www.sevenbank.co.jp/intlcard/index2.html 7-Eleven]''' convenience stores,
* at '''[https://www.family.co.jp/for_tourist/en.html Family Mart]''' convenience stores,
* and during office hours in Japanese Post offices.
Do not bother with the local banks ATMs, most of which do not accept overseas cards.
To be on the safe side, you could exchange a few tens of thousands of yens in advance. Compare prices and avoid the extortionate bureaux de change at airports!

=== Electronic payments ===

For small day-to-day purchases, you should procure a FeliCa electronic payment card, a.k.a. an ''IC'' card. It can be used to enter and exit public transports (train, metro, bus, etc), to check out at convenience stores and many shops. You can load the card with Japanese bank notes at dedicated machines. There are two options in Tokyo area:

*Keikyu at Haneda airport
|}
Tourist cards with their cutesy design are meant to keep as memento and provide third-party discounts. But beware that they expire after 28 days (including any unused credit).

== Electricity ==
Japan has the lowest household voltage in the world, so '''check the specifications''' on your power adapters.
Outlets are not compatible with European or Commonwealth plugs. North American ''grounded'' plugs (with 3 pins) are also troublesome.
Most attendees will thus need passive adapters. They are easier to find at home, so '''BUY BEFORE DEPARTURE'''.
{| class="wikitable"
!Voltage
|100 V
|-
!Frequency
|50 Hz (60 Hz in Kyoto/Osaka)
|-
!Socket
|Type A with only 2 pins (i.e. ungrounded)
|}

== Connectivity ==

The telephone prefix for Japan is '''+81'''.

=== Mobile data ===
You can buy, or better yet pre-order, a prepaid data SIM card at international arrivals at the airport.
Don't postpone, as it might be difficult to find elsewhere.

=== Wireless LAN ===
Free Wi-Fi access points are common, but they may need registration, possibly in Japanese only.
There is a map of known Wi-Fi access points in the '''JNTO''' app (see [[#Transportation]]).

=== Group Chat ===
Participants can share information and discuss using the dedicated [https://t.me/joinchat/GIwXP1WmM84pbxCXStaUew VDD 2019 Telegram group].

== Emergency ==

'''119''' is the fire and ambulance emergency number in Japan. '''110''' is the local police number.

Please carry your travel insurance card or certificate on you at all times.
If you do not have a travel insurance yet, buy a fixed-term one before you depart. EU social security cards are not '''not''' valid in Japan.
Advise your relatives, and if applicable, your government:
* [https://pastel.diplomatie.gouv.fr/fildariane/dyn/public/login.html Registration for French citizens].

Personal safety risks in Japan primarily stem from natural disasters:
* [https://www.jnto.go.jp/safety-tips/eng/index.html '''JNTO''' safety tips]
** on [https://play.google.com/store/apps/details?id=jp.co.rcsc.safetyTips.android Google Play Store]
** or [https://apps.apple.com/us/app/safety-tips/id858357174 Apple App Store].
* In case of earthquake:
** Seek cover (e.g. under a table) if indoors,
** Get away from structures (especially glass windows) if outdoors.
** After the quake, get away from the shore onto high ground away from tidal waves.
* In case of typhoon, follow instructions from authorities. Typhoon are predicted several days ahead.

'''NOTE''': VideoLAN does not refund taxi, car rental and public transport.

=== Rail pass ===
If you have a voucher for a rail pass, you should save it for before or after the conferencing days. JR passes are of limited within central Tokyo. They are valid for the ''Yamanote'' loop and the ''Chuo-Sobu'' east-west transverse train lines, as well as JR-operated buses, but not on the metro networks.

== Means of payment ==

VISA and MasterCard cards are '''not''' universally accepted in Japan.

=== Cash ===
You will need to withdraw cash from an ''international'' ATM (accepting VISA, MasterCard, AmEx, Discovery and UnionPay). You can find those:
* at arrivals in the airport terminal,
* at '''[https://www.sevenbank.co.jp/intlcard/index2.html 7-Eleven]''' convenience stores,
* at '''[https://www.family.co.jp/for_tourist/en.html Family Mart]''' convenience stores,
* and during office hours in Japanese Post offices.
Do not bother with the local banks ATMs, most of which do not accept overseas cards.
To be on the safe side, you could exchange a few tens of thousands of yens in advance. Compare prices and avoid the extortionate bureaux de change at airports!

=== Electronic payments ===

For small day-to-day purchases, you should procure a FeliCa electronic payment card, a.k.a. an ''IC'' card. It can be used to enter and exit public transports (train, metro, bus, etc), to check out at convenience stores and many shops. You can load the card with Japanese bank notes at dedicated machines. There are two options in Tokyo area:

{| class="wikitable"
!Vendor
!Regular card
!Tourist card
!Tourist point of sale
|-
!JR East
|[https://www.jreast.co.jp/e/pass/suica.html Suica] ¥500 deposit
|[https://www.jreast.co.jp/e/welcomesuica/welcomesuica.html Welcome Suica] free??
|JR East Travel Service Center
|-
!Tokyo Metro
|[https://www.pasmo.co.jp/visitors/en/normalpasmo/ Pasmo] ¥500 deposit
|[https://www.pasmo.co.jp/visitors/en/about/ Pasmo passport] ¥500
|
*Keisei at Narita airport
*Keikyu at Haneda airport
|}
Tourist cards with their cutesy design are meant to keep as memento and provide third-party discounts. But beware that they expire after 28 days (including any unused credit).

== Electricity ==
Japan has the lowest household voltage in the world, so '''check the specifications''' on your power adapters.
Outlets are not compatible with European or Commonwealth plugs. North American ''grounded'' plugs (with 3 pins) are also troublesome.
Most attendees will thus need passive adapters. They are easier to find at home, so '''BUY BEFORE DEPARTURE'''.
{| class="wikitable"
!Voltage
|100 V
|-
!Frequency
|50 Hz (60 Hz in Kyoto/Osaka)
|-
!Socket
|Type A with only 2 pins (i.e. ungrounded)
|}

== Connectivity ==

The telephone prefix for Japan is '''+81'''.

=== Mobile data ===
You can buy, or better yet pre-order, a prepaid data SIM card at international arrivals at the airport.
Don't postpone, as it might be difficult to find elsewhere.

=== Wireless LAN ===
Free Wi-Fi access points are common, but they may need registration, possibly in Japanese only.
There is a map of known Wi-Fi access points in the '''JNTO''' app (see [[#Transportation]]).

=== Group Chat ===
Participants can share information and discuss using the dedicated [https://t.me/joinchat/GIwXP1WmM84pbxCXStaUew VDD 2019 Telegram group].

== Emergency ==

'''119''' is the fire and ambulance emergency number in Japan. '''110''' is the local police number.

Please carry your travel insurance card or certificate on you at all times.
If you do not have a travel insurance yet, buy a fixed-term one before you depart. EU social security cards are not '''not''' valid in Japan.
Advise your relatives, and if applicable, your government:
* [https://pastel.diplomatie.gouv.fr/fildariane/dyn/public/login.html Registration for French citizens].

Personal safety risks in Japan primarily stem from natural disasters:
* [https://www.jnto.go.jp/safety-tips/eng/index.html '''JNTO''' safety tips]
** on [https://play.google.com/store/apps/details?id=jp.co.rcsc.safetyTips.android Google Play Store]
** or [https://apps.apple.com/us/app/safety-tips/id858357174 Apple App Store].
* In case of earthquake:
** Seek cover (e.g. under a table) if indoors,
** Get away from structures (especially glass windows) if outdoors.
** After the quake, get away from the shore onto high ground away from tidal waves.
* In case of typhoon, follow instructions from authorities. Typhoon are predicted several days ahead.

= Contact =

The VideoLAN Dev Days are organized by the board members of the VideoLAN non-profit organization:
* Jean-Baptiste Kempf,
* Denis Charmet,
* Konstantin Pavlov, and
* Hugo Beauzée-Luyssen.

Chouquette: /* Other ideas for VLC & libVLC */

{{DISPLAYTITLE:Google Summer of Code 2018}}


https://developers.google.com/open-source/gsoc/images/gsoc2016-sun-373x373.png


This page summarize the current list of ideas for VideoLAN project, for [https://summerofcode.withgoogle.com Google Summer Of Code 2018].

The list is not exhaustive, and is not limitative. Feel free to apply with '''your own idea!'''

== Introduction & Information ==
[[File:Asterix VLC.svg|frameless|right]]

This wiki page covers the attempt by the [[VideoLAN]] project to act as a mentoring organization for [http://code.google.com/soc/ Google Summer of Code], in order to improve [[VLMC]] and [[VLC]] (or the [[libVLC]] engine).

=== Summer of Code ===

Google Summer of Code is a way for '''university students''' to have a paid '''internship''' by '''Google''' to work on open source projects and become top developers!

[[VideoLAN]] was a ''Google Summer of Code'' mentoring organization in [[SoC 2007|2007]], [[SoC 2008|2008]], [[SoC 2009|2009]], [[SoC 2010|2010]], [[SoC 2011|2011]], [[SoC 2013|2013]], [[SoC 2016|2016]] and [[SoC_2017|2017]].

This page list some ideas for Summer of Code projects on VLMC, libVLC and {{VLC}}.

=== VLC & libVLC ===

{{VLC}} is a cross-platform multimedia player, encoder and streamer application. It is one of the most successful open-source projects without any professional structure underneath.

{{VLC}} is downloaded at an approximate monthly rate of 23 millions from the main website and that's not including third-party distributions (Linux)!

You can find more information on [http://en.wikipedia.org/wiki/VLC_media_player VLC on Wikipedia] or on this [[Main Page|wiki]].

The engine of VLC is '''libVLC''', and is used by '''VLMC'''.

=== VideoLAN Movie Creator ===
[[VLMC]] is a cross-platform non-linear video editing software based on libVLC technology. It was started as a final year student project at the French IT school [http://www.epitech.eu EPITECH].

[[VLMC]] currently awaits a transition to the current libvlc API and it's actual 1.0 release!

=== Summer of Code ===

If selected and developed, SoC projects for VLMC and VLC will be included in later releases.

All projects are covered by the GPL (v2+) or LGPL (v2.1+) licenses depending on the module.

== How to Start ==
=== Find an idea ===
First, you need to find an idea.

This current page gives you a list of ideas. Those ideas are '''NOT exhaustive''': you can bring your own idea! Some of the best ideas we've ever had were '''custom''' ideas!

=== Submit your idea ===
You need to submit your idea on the ''Google Summer of Code'' platform.

You should do so, very quickly, even before having finished compilation and the next steps, so that we can give you early feedback.

=== Compile libVLC or VLMC ===
This may sound trivial, but it's harder than many expect. See https://wiki.videolan.org/Category:Building/ for more informations.

You should come on [[IRC]] to get help to compile.

=== Provide a small patch ===
To demonstrate your skills, share a small patch with us. This will let you become familiar with [[Git]], in case you don't know it already and our process on [[Sending Patches VLC|merging patches]].

=== Let's get in touch ===

If you have a doubt, are not sure about anything or want clarification, please get in touch with us.

We have 3 major communication channels: Our [https://mailman.videolan.org/mailman/listinfo mailing-lists] to discuss patches and further development related topics. Furthermore, we have our [http://forum.videolan.org web forums] for VLC-related end-user support - a VLMC section will be created once the product is published. Finally, there is our IRC channel ''#videolan'' (for libVLC) and ''#vlmc'' on the ''Freenode'' network. It's open to any kind of discussion. Usage issues, questions how to compile VLC/VLMC, getting to know the fellow developers, etc.

= Ideas for VLC & libVLC =

== libVLC AirPlay support ==

'''Project Description''':
libVLC is now able to send video to the ChromeCast devices. We want to be able to do the same using the Airplay protocol, for Apple devices.

We want to be able to cast from any device, including Android or Windows machines, on all support Airplay devices, like Apple TV, iOS devices and audio amplificators.

This will use the new renderer APIs added in libVLC 3.0. Those APIs will need to be extended to allow the renderer to kick in during the playback.

'''Tasks to do''':
The work will consist of the following tasks:
* documentation on the [https://nto.github.io/AirPlay.html AirPlay protocol],
* documentation on the '''RAOP''' VLC module,
* implementation of the detection/discovery of the supported devices,
* implementation of the protocol to discuss with the device,
* modify the device control in order to transcode on demand,
* polish and release.

'''Advice'''
Please have a look at the following files: {{file|modules/stream_out/chromecast/chromecast_ctrl.cpp|Chromecast}} {{file|include/vlc_renderer_discovery.h|renderer API}}
A motivated and fast enough student could pair this task with the UPnP renderer!

'''Requirements''':
This project requires '''C''' knowledge and access to some Airplay devices.

''Proposed mentor: steve''

=== Bonus: AirPlay target ===

See https://trac.videolan.org/vlc/ticket/5752

== libVLC UPnP renderer support ==

'''Project Description''':
libVLC is now able to send video to the ChromeCast devices. We want to be able to do the same using the UPnP Renderer protocol, for all the connected TV devices that support this protocol.

We want to be able to do that from any device, including Android, iOS or Windows machines.

This will use the new renderer APIs added in libVLC 3.0. Those APIs will need to be extended to allow the renderer to kick in during the playback.

'''Tasks to do''':
The work will consist of the following tasks:
* documentation on the [http://upnp.org/resources/documents/UPnP_AV_tutorial_July2014.pdf UPnP renderer] protocol and on the libupnp APIs,
* implementation of the detection/discovery of the supported devices,
* implementation of the protocol to discuss with the device,
* modify the control of the device in order to transcode on demand,
* polish and release.

'''Advice''':
Please have a look at the following files: {{file|modules/stream_out/chromecast/chromecast_ctrl.cpp|Chromecast}} {{file|include/vlc_renderer_discovery.h|renderer API}}
A motivated and fast enough student could pair this task with the Airplay renderer!

'''Requirements''':
This project requires '''C''' knowledge and access to some connected TV supporting this protocol.

''Proposed mentor: tguillem''

== Advanced Audio Filters ==

'''Project Description''':
We are looking for a skilled audiophile that knows a lot about audio theory and practice to work on new audio filters for VLC.

'''Tasks to do''':
* SRS WoW like or other 3D effects;
* channels mixing, notably upmixing, like Prologic-II;
* tracks mixing, and transitions;
* scriptable new audio filters in lua and enable users to create whatever audio filtering function they want in a Lua script;
* LADSPA or other libraries integration.

'''Requirements''':
This project needs some good audio knowledge and good C experience.

'''Qualification task:'''
Port any audio filter from MPlayer

''Proposed mentor: geal ''

== libVLC VR support ==
'''Project Description''':
libVLC is able to play most 2D and 360 videos, but the support of VR is very limited.

Because of 360 and VR support, the attention about '''VR''' is getting very popular those days. We need to support that in libVLC, with an Oculus, a Vive, or a similar headset.

'''Tasks to do''':
* understand the different types of 360, 360-stereo, VR movie types and the different headsets types,
* integrate a new headset view in a libvlccore module,
* integrate a new headset control in a libvlccore module, to get rotation,
* integrate the control UI with the headset,
* optionaly code a VR theater mode inside the OpenGL or D3D module.

'''Requirements''':
This project requires '''C''' knowledge and access to a VR headset.

''Proposed mentor: adrien''

== VLC Qt interface redesign ==
'''Project Description''':
The VLC interface is quite outdated on Linux and Windows. It has a lot of features, but some are not properly exposed.

This project for the summer is to rework heavily this interface to make it beautiful and useful again.

'''Scope of the tasks to do''':

The idea is to get closer to what the WinRT/UWP interface looks like ''(search on google image to get an idea)'', but other ideas are welcome.

The WinRT interface is simpler, more user friendly, and has a better "media center" feel into it.

It would require integration with the media library and with the current interface.

Qml is the preferred way of improving the current UI.

'''Requirements''':
This project requires '''Qt/C++''' knowledge.

''Proposed mentor: J-B''

== VLC macOS interface redesign ==
'''Project Description''':
The VLC interface is quite outdated on macOS.

This project for the summer is to rework heavily this interface to make it beautiful and useful again.

'''Scope of the tasks to do''':

The idea is to get closer to what the Apple TV/iOS interface looks like ''(search on google image to get an idea)'', but other ideas are welcome.

The iOS/AppleTV interface is simpler, more user friendly, and has a better "media center" feel into it.

It would require integration with the media library and with the current interface.

Starting from the current UI is a requirement.

'''Requirements''':
This project requires '''Obj-C''' knowledge.

''Proposed mentor: David Fuhrmann, Felix Paul Kühne''

== VLCKit Testsuite ==
'''Project Description''':
VLCKit is the wrapper framework around libvlc that powers VLC for iOS and the respective tvOS app.
The framework is furthermore used by thousands of Apps all over the world and subject to everyday change.

Sadly it currently doesn't have any tests that ensure the stability of playback and deterministic behavior.
This frequently leads to regressions that are noticed too late and unexpected behavior that sometimes even make it into the Appstore.

The project for this summer is to build a Testsuite around VLCKit to ensure that the framwork becomes and stays stable.
This indirectly has a huge impact on the stability of the macOS app since iOS and macOS share a code base.

'''Tasks to do''':

*Get an overview of the current behavior of the Framework.
*Write a suite with different testtargets to ensure the correct behavior of every single class
*Use so called "stubbing" and "mocking" of classes for testing purposes
*Make sure that the testtarget runs once every day on jenkins to ensure that no regressions have been introduced.

'''Requirements''':
This project requires '''Obj-C''' knowledge and ideally knowledge of writing tests for iOS but this can be learned.

''Proposed mentor: Carola Nitz, Felix Paul Kühne''

== VLC cryptographic updates ==
'''Project Description''':
VLC is already using '''GPG signatures''' to achieve secure updates on the Windows platform.

But the updates are currently signed
with a single master key which is pinned into the source code and VLCs in the wild aren't able to check for revocations of this key.

'''Tasks to do''':

Therefore we would like to improve this situation by:

* being able to sign developers' keys that can sign VLC binaries on behalf of this master key
* support revocations of these developer's key
* provide a master key upgrade path

'''Requirements''':
This project requires solid notions of '''C and Crypto'''.

''Proposed mentor: geal''

== Move VLC build system to Meson Build ==
'''Project Description''':
VLC Currently uses autotools but using Meson would make it easier to use it with IDEs and use a more modern language.

This project for the summer is to build the core VLC, its modules and libvlc with Meson Build on Linux, Windows, MacOS and possibly Android, iOS and Universal Windows.

'''Scope of the tasks to do''':

Building VLC can be tricky because of all the dependencies and reliance on autotools. Using a meta-build system like [http://mesonbuild.com/ Meson Build] would make things easier. Because we support a lot of platforms it can also be tricky to handle all the configurations where VLC can be built.

Integration in XCode and Visual Studio should help with such a meta-build system. It would also help the integration of other languages like Rust in the whole project.

Building some of the contribs with Meson Build would be a good plus.

'''Requirements''':
This project requires '''Python''', '''autotools''' and '''bash''' knowledge.

''Proposed mentor: Steve Lhomme''

== GPU shader filters ==
'''Project Description''':
VLC is using OpenGL and Direct3D11 on modern machines. It is now possible to do all kinds of video processing that was done in the CPU directly in the GPU.

This project for the summer is to port some of the existing CPU filters to the GPU using shaders.

'''Scope of the tasks to do''':

The first task will be to identify all the video filters in VLC and identify the ones that could be done as shaders. Then implement them. Either in OpenGL shaders, Direct3D11 shaders, both and maybe Vulkan.

'''Requirements''':
This project requires '''OpenGL''' or '''Direct3D11''' shaders knowledge as well as knowledge on video filters in general.

''Proposed mentor: Steve Lhomme''

== libplacebo integration and improvement ==
'''Project Description''':
libplacebo (https://github.com/haasn/libplacebo) is a new library for GPU-accelerated video/image rendering primitives.

VLC is using OpenGL and Direct3D11 on modern machines via its own plugins. We plan to use future graphics library (Metal and Vulkain) via libplacebo (that will implements them).
libplacebo also handle colorimetry via shaders (only OpenGL for now) or via future graphic library API.
It will or already support HDR, jinc scaling, debanding...

This project for the summer is to add Metal/OpenGL/Direct3D support inside libplacebo, improve libplacebo and integrate it inside VLC as modules.

'''Scope of the tasks to do''':

1. Implement vulkan context creation inside VLC using libplacebo or direct Vulkan API calls

2. Implement a new libplacebo video output module

3. Add the missing features to libplacebo and make it production-ready (needs lots of testing)

4. Implement support for more graphics APIs: OpenGL, Direct3D 11, Metal (via MoltenVK ?)

Tasks 1/2 and 3/4 can be done by 2 students in parallel.

'''Requirements''':
This project requires '''C''', '''OpenGL''', '''Vulkan''', '''Metal''', or '''generic image processing''' knowledge as well as knowledge on VLC vout display/window plugins.

More information about missing features and Metal support on the following discussion: https://mailman.videolan.org/pipermail/vlc-devel/2018-March/118229.html

''Proposed mentor: Thomas Guillem''

= Ideas for VLMC =

== Port to Android ==

'''Project Description''':
VLMC is now working on the desktop. It would be nice to port it also to the mobile world, starting by Android.

This project would require to adapt to smaller screens, and simplify the UI to fit the Android workflow.

'''Tasks to do''':
# Fix the VLMC build for Android. As libVLC works fine on Android, this is more focused on compiling the Qt part for Android.
# Split more parts of the UI in components that are reusable on mobile.
# Change the components to fit the small resolutions of the Android devices.
# Rewrite some UI components in QML.
# Write a simpler timeline widget for Mobile workflows.

'''Requirements''': This project requires '''C++/Qt/qml''' knowledge, and access to Android devices.

''Proposed mentors: Geoffrey/Hugo''

== Port to iOS ==

'''Project Description''':
VLMC is now working on the desktop. It would be nice to port it also to the mobile world, also on iOS.

This project would require to adapt to smaller screens, and simplify the UI to fit the iOS workflow.

'''Tasks to do''':
# Fix the VLMC build for iOS. As libVLC works fine on iOS, this is more focused on compiling the Qt part for iOS.
# Split more parts of the UI in components that are reusable on mobile.
# Change the components to fit the small resolutions of the iOS devices.
# Rewrite some UI components in QML.
# Write a simpler timeline widget for Mobile workflows.

'''Requirements''': This project requires '''C++/Qt/qml''' knowledge, and access to Android devices.

''Proposed mentors: Felix/Hugo''

== Media Workflow rework ==

'''Project Description''':
VLMC is now working on the desktop, but the media workflow is quite slow and is missing some common use cases.

This should be fixed in [https://github.com/mltframework/mlt MLT] framework backend for libVLC and is the continuation from the work from the previous Summer of Code.

'''Tasks to do''':
# Understand the MLT libVLC backend codebase,
# Clean the backend and port it to a cleaner code state in C++,
# Benchmark the code and make it more efficient,
# Work to merge this backend upstream,
# Implement all the missing features in libVLC.

'''Requirements''': This project requires '''C/C++''' knowledge, and understanding of multimedia concepts is a good positive point.

''Proposed mentors: Hugo''

== Workflow audio filters ==

'''Project Description''':
VLMC is now working on the desktop, but we need to have a good setup of audio filters to make it usable for most people.

'''Tasks to do''':
# Understand the VLMC and MLT codebase interactions,
# Add audio filters on the MLT framework backend using the [https://en.wikipedia.org/wiki/LADSPA LADSPA]/[http://lv2plug.in/ LV2] library or a similar open source library,
# Code the interface corresponding to those filters, and their options,
# Prepare visualizations, and notably for soundwave filters,
# Integrate those inside the timeline UI,
# Optimize.

'''Requirements''': This project requires '''C++/Qt/qml''' knowledge, and enough understanding of audio.

''Proposed mentors: J-B''

== Workflow video filters ==

'''Project Description''':
VLMC is now working on the desktop, but we need to have a good setup of video filters to make it usable for most people.

'''Tasks to do''':
# Understand the VLMC and MLT codebase interactions,
# Add video filters on the MLT framework backend using the [https://git.sesse.net/?p=movit;a=summary movit] library or a similar open source library,
# Code the interface corresponding to those filters, and their options,
# Add transitions between clips
# Code the interface to manage those transitions,
# Optimize the code.

'''Requirements''': This project requires '''C/C++''' knowledge.

''Proposed mentors: Felix''

== Improve multiplatform support ==
VLMC is aiming at being fully cross platform, but drifted a bit from that goal. While most VLMC's code is cross platform, and can be easily built targeting platforms, some dependencies might prove more difficult to build or compose with VLMC.

'''Tasks to do''':
# Fix MLT cross compilation for Windows (This will most likely require patching directly inside MLT, all contributions must be sent upstream).
# Fix medialibrary code & build process on macOS (and potentially iOS). The medialibrary misses some platform specific code to be able to list all connected drives (hard drives & USB removable storage, mostly) along with filesystem browsing
# Update the documentation along the way
# Create jenkins build configuration to have nightly builds on jenkins.videolan.org & nightlies.videolan.org for all supported platforms

'''Requirements''': This project requires buildsystems/toolchains knowledge, basic system programming on macOS & Windows

''Proposed mentors: Hugo''

== Remote UI ==

We would like to have a way to use VLMC from a web browser. You can easily imagine having a nice, shiny & simple UI for minimal movie edition, which would go hand in hand with the cloud storage feature.

'''Tasks to do''':
This task aims toward the uncoupling of the rendering backend & UI, as the renderer will run server side, while the UI runs on the client side.

The idea is to be able to have a UI interacting with the renderer without having to be in the same process, or even machine.

'''Requirements''': This project requires '''C++''' and '''JS''' knowledge.

''Proposed mentor'': jb, chouquette, fkuehne

= Ideas for VLC dependencies =

== libmicrodns refactoring ==

Our current mDNS discoverer is working, but is not so respectful of the RFC.
Possible improvements include:
* Device TTL support
* Device removal detection
* Better request pacing
* Delegate socket interactions to the caller
* Unit testing
* Fuzzing

'''Requirements''': This project require '''C''' knowledge, as well as system programming skills

''Proposed mentor'': chouquette, tguillem

== libdsm SMBv2/3 support ==

libdsm works great for SMBv1, but doesn't support later version of the protocol. This will become a problem soon, and we need to fix it.

Possible improvements include:
* SMBv2 support
* SMBv3 support
* Unit testing
* Fuzzing

'''Requirements''': This project require '''C''' knowledge, as well as system programming skills

''Proposed mentor'': chouquette, tguillem

= Other ideas for VLC & libVLC =

Those ideas are not detailed, but they are ideas that we could help to spring new ideas.

* Integrate Rust inside VLC, as a demuxer or a parser
* Improve the SMB/Samba share library
* Work on Vulkan output for VLC
* VLC javascript work
* Improve fast-seek in MP4 and WMV demuxers
* Improve id3 tag parsing.

* Provide setups for popular streaming services / sout templates (ui ?)
* Bridge module for GMI'C or other video filters
* Automated Testing Environment like ffmpeg Fate (port ?) for demuxing, non hw decoding

Finally, there is our IRC channel ''#videolan'' (for libVLC) and ''#vlmc'' on the ''Freenode'' network. It's open to any kind of discussion. Usage issues, questions how to compile VLC/VLMC, getting to know the fellow developers, etc.

= Ideas for VLC & libVLC =

== libVLC AirPlay support ==

'''Project Description''':
libVLC is now able to send video to the ChromeCast devices. We want to be able to do the same using the Airplay protocol, for Apple devices.

We want to be able to cast from any device, including Android or Windows machines, on all support Airplay devices, like Apple TV, iOS devices and audio amplificators.

This will use the new renderer APIs added in libVLC 3.0. Those APIs will need to be extended to allow the renderer to kick in during the playback.

'''Tasks to do''':
The work will consist of the following tasks:
* documentation on the [https://nto.github.io/AirPlay.html AirPlay protocol],
* documentation on the '''RAOP''' VLC module,
* implementation of the detection/discovery of the supported devices,
* implementation of the protocol to discuss with the device,
* modify the device control in order to transcode on demand,
* polish and release.

'''Advice'''
Please have a look at the following files: {{file|modules/stream_out/chromecast/chromecast_ctrl.cpp|Chromecast}} {{file|include/vlc_renderer_discovery.h|renderer API}}
A motivated and fast enough student could pair this task with the UPnP renderer!

'''Requirements''':
This project requires '''C''' knowledge and access to some Airplay devices.

''Proposed mentor: steve''

=== Bonus: AirPlay target ===

See https://trac.videolan.org/vlc/ticket/5752

== libVLC UPnP renderer support ==

== Advanced Audio Filters ==

'''Project Description''':
We are looking for a skilled audiophile that knows a lot about audio theory and practice to work on new audio filters for VLC.

'''Tasks to do''':
* SRS WoW like or other 3D effects;
* channels mixing, notably upmixing, like Prologic-II;
* tracks mixing, and transitions;
* scriptable new audio filters in lua and enable users to create whatever audio filtering function they want in a Lua script;
* LADSPA or other libraries integration.

'''Requirements''':
This project needs some good audio knowledge and good C experience.

'''Qualification task:'''
Port any audio filter from MPlayer

''Proposed mentor: geal ''

== libVLC VR support ==
'''Project Description''':
libVLC is able to play most 2D and 360 videos, but the support of VR is very limited.

Because of 360 and VR support, the attention about '''VR''' is getting very popular those days. We need to support that in libVLC, with an Oculus, a Vive, or a similar headset.

'''Tasks to do''':
* understand the different types of 360, 360-stereo, VR movie types and the different headsets types,
* integrate a new headset view in a libvlccore module,
* integrate a new headset control in a libvlccore module, to get rotation,
* integrate the control UI with the headset,
* optionaly code a VR theater mode inside the OpenGL or D3D module.

'''Requirements''':
This project requires '''C''' knowledge and access to a VR headset.

''Proposed mentor: adrien''

== VLC Qt interface redesign ==
'''Project Description''':
The VLC interface is quite outdated on Linux and Windows. It has a lot of features, but some are not properly exposed.

This project for the summer is to rework heavily this interface to make it beautiful and useful again.

'''Scope of the tasks to do''':

The idea is to get closer to what the WinRT/UWP interface looks like ''(search on google image to get an idea)'', but other ideas are welcome.

The WinRT interface is simpler, more user friendly, and has a better "media center" feel into it.

It would require integration with the media library and with the current interface.

Qml is the preferred way of improving the current UI.

'''Requirements''':
This project requires '''Qt/C++''' knowledge.

''Proposed mentor: J-B''

== VLC macOS interface redesign ==
'''Project Description''':
The VLC interface is quite outdated on macOS.

This project for the summer is to rework heavily this interface to make it beautiful and useful again.

'''Scope of the tasks to do''':

The idea is to get closer to what the Apple TV/iOS interface looks like ''(search on google image to get an idea)'', but other ideas are welcome.

The iOS/AppleTV interface is simpler, more user friendly, and has a better "media center" feel into it.

It would require integration with the media library and with the current interface.

Starting from the current UI is a requirement.

'''Requirements''':
This project requires '''Obj-C''' knowledge.

''Proposed mentor: David F''

== VLC cryptographic updates ==
'''Project Description''':
VLC is already using '''GPG signatures''' to achieve secure updates on the Windows platform.

But the updates are currently signed
with a single master key which is pinned into the source code and VLCs in the wild aren't able to check for revocations of this key.

'''Tasks to do''':

Therefore we would like to improve this situation by:

* being able to sign developers' keys that can sign VLC binaries on behalf of this master key
* support revocations of these developer's key
* provide a master key upgrade path

'''Requirements''':
This project requires solid notions of '''C and Crypto'''.

''Proposed mentor: geal''

== Move VLC build system to Meson Build ==
'''Project Description''':
VLC Currently uses autotools but using Meson would make it easier to use it with IDEs and use a more modern language.

This project for the summer is to build the core VLC, its modules and libvlc with Meson Build on Linux, Windows, MacOS and possibly Android, iOS and Universal Windows.

'''Scope of the tasks to do''':

Building VLC can be tricky because of all the dependencies and reliance on autotools. Using a meta-build system like [http://mesonbuild.com/ Meson Build] would make things easier. Because we support a lot of platforms it can also be tricky to handle all the configurations where VLC can be built.

Integration in XCode and Visual Studio should help with such a meta-build system. It would also help the integration of other languages like Rust in the whole project.

Building some of the contribs with Meson Build would be a good plus.

'''Requirements''':
This project requires '''Python''', '''autotools''' and '''bash''' knowledge.

''Proposed mentor: Steve Lhomme''

== GPU shader filters ==
'''Project Description''':
VLC is using OpenGL and Direct3D11 on modern machines. It is now possible to do all kinds of video processing that was done in the CPU directly in the GPU.

This project for the summer is to port some of the existing CPU filters to the GPU using shaders.

'''Scope of the tasks to do''':

The first task will be to identify all the video filters in VLC and identify the ones that could be done as shaders. Then implement them. Either in OpenGL shaders, Direct3D11 shaders, both and maybe Vulkan.

'''Requirements''':
This project requires '''OpenGL''' or '''Direct3D11''' shaders knowledge as well as knowledge on video filters in general.

''Proposed mentor: Steve Lhomme''

= Ideas for VLMC =

== Port to Android ==

'''Project Description''':
VLMC is now working on the desktop. It would be nice to port it also to the mobile world, starting by Android.

This project would require to adapt to smaller screens, and simplify the UI to fit the Android workflow.

'''Tasks to do''':
# Fix the VLMC build for Android. As libVLC works fine on Android, this is more focused on compiling the Qt part for Android.
# Split more parts of the UI in components that are reusable on mobile.
# Change the components to fit the small resolutions of the Android devices.
# Rewrite some UI components in QML.
# Write a simpler timeline widget for Mobile workflows.

'''Requirements''': This project requires '''C++/Qt/qml''' knowledge, and access to Android devices.

''Proposed mentors: Geoffrey/Hugo''

== Port to iOS ==

'''Project Description''':
VLMC is now working on the desktop. It would be nice to port it also to the mobile world, also on iOS.

This project would require to adapt to smaller screens, and simplify the UI to fit the iOS workflow.

'''Tasks to do''':
# Fix the VLMC build for iOS. As libVLC works fine on iOS, this is more focused on compiling the Qt part for iOS.
# Split more parts of the UI in components that are reusable on mobile.
# Change the components to fit the small resolutions of the iOS devices.
# Rewrite some UI components in QML.
# Write a simpler timeline widget for Mobile workflows.

'''Requirements''': This project requires '''C++/Qt/qml''' knowledge, and access to Android devices.

''Proposed mentors: Felix/Hugo''

== Media Workflow rework ==

'''Project Description''':
VLMC is now working on the desktop, but the media workflow is quite slow and is missing some common use cases.

This should be fixed in [https://github.com/mltframework/mlt MLT] framework backend for libVLC and is the continuation from the work from the previous Summer of Code.

'''Tasks to do''':
# Understand the MLT libVLC backend codebase,
# Clean the backend and port it to a cleaner code state in C++,
# Benchmark the code and make it more efficient,
# Work to merge this backend upstream,
# Implement all the missing features in libVLC.

'''Requirements''': This project requires '''C/C++''' knowledge, and understanding of multimedia concepts is a good positive point.

''Proposed mentors: Hugo''

== Workflow audio filters ==

'''Project Description''':
VLMC is now working on the desktop, but we need to have a good setup of audio filters to make it usable for most people.

'''Tasks to do''':
# Understand the VLMC and MLT codebase interactions,
# Add audio filters on the MLT framework backend using the [https://en.wikipedia.org/wiki/LADSPA LADSPA]/[http://lv2plug.in/ LV2] library or a similar open source library,
# Code the interface corresponding to those filters, and their options,
# Prepare visualizations, and notably for soundwave filters,
# Integrate those inside the timeline UI,
# Optimize.

'''Requirements''': This project requires '''C++/Qt/qml''' knowledge, and enough understanding of audio.

''Proposed mentors: J-B''

== Workflow video filters ==

'''Project Description''':
VLMC is now working on the desktop, but we need to have a good setup of video filters to make it usable for most people.

'''Tasks to do''':
# Understand the VLMC and MLT codebase interactions,
# Add video filters on the MLT framework backend using the [https://git.sesse.net/?p=movit;a=summary movit] library or a similar open source library,
# Code the interface corresponding to those filters, and their options,
# Add transitions between clips
# Code the interface to manage those transitions,
# Optimize the code.

'''Requirements''': This project requires '''C/C++''' knowledge.

''Proposed mentors: Felix''

== Improve multiplatform support ==
VLMC is aiming at being fully cross platform, but drifted a bit from that goal. While most VLMC's code is cross platform, and can be easily built targeting platforms, some dependencies might prove more difficult to build or compose with VLMC.

'''Tasks to do''':
# Fix MLT cross compilation for Windows (This will most likely require patching directly inside MLT, all contributions must be sent upstream).
# Fix medialibrary code & build process on macOS (and potentially iOS). The medialibrary misses some platform specific code to be able to list all connected drives (hard drives & USB removable storage, mostly) along with filesystem browsing
# Update the documentation along the way
# Create jenkins build configuration to have nightly builds on jenkins.videolan.org & nightlies.videolan.org for all supported platforms

'''Requirements''': This project requires buildsystems/toolchains knowledge, basic system programming on macOS & Windows

''Proposed mentors: Hugo''

== Remote UI ==

We would like to have a way to use VLMC from a web browser. You can easily imagine having a nice, shiny & simple UI for minimal movie edition, which would go hand in hand with the cloud storage feature.

'''Tasks to do''':
This task aims toward the uncoupling of the rendering backend & UI, as the renderer will run server side, while the UI runs on the client side.

The idea is to be able to have a UI interacting with the renderer without having to be in the same process, or even machine.

'''Requirements''': This project requires '''C++''' and '''JS''' knowledge.

* Device removal detection
* Better request pacing
* Delegate socket interactions to the caller
* Unit testing
* Fuzzing

'''Requirements''': This project require '''C''' knowledge, as well as system programming skills

''Proposed mentor'': chouquette, tguillem

== libdsm SMBv2/3 support ==

libdsm works great for SMBv1, but doesn't support later version of the protocol. This will become a problem soon, and we need to fix it.

Possible improvements include:
* SMBv2 support
* SMBv3 support
* Unit testing
* Fuzzing

'''Requirements''': This project require '''C''' knowledge, as well as system programming skills

{{DISPLAYTITLE:Google Summer of Code 2018}}


https://developers.google.com/open-source/gsoc/images/gsoc2016-sun-373x373.png


This page summarize the current list of ideas for VideoLAN project, for [https://summerofcode.withgoogle.com Google Summer Of Code 2018].

The list is not exhaustive, and is not limitative. Feel free to apply with '''your own idea!'''

== Introduction & Information ==
[[File:Asterix VLC.svg|frameless|right]]

This wiki page covers the attempt by the [[VideoLAN]] project to act as a mentoring organization for [http://code.google.com/soc/ Google Summer of Code], in order to improve [[VLMC]] and [[VLC]] (or the [[libVLC]] engine).

=== Summer of Code ===

Google Summer of Code is a way for '''university students''' to have a paid '''internship''' by '''Google''' to work on open source projects and become top developers!

[[VideoLAN]] was a ''Google Summer of Code'' mentoring organization in [[SoC 2007|2007]], [[SoC 2008|2008]], [[SoC 2009|2009]], [[SoC 2010|2010]], [[SoC 2011|2011]], [[SoC 2013|2013]], [[SoC 2016|2016]] and [[Soc_2017|2017]].

This page list some ideas for Summer of Code projects on VLMC, libVLC and {{VLC}}.

=== VLC & libVLC ===

{{VLC}} is a cross-platform multimedia player, encoder and streamer application. It is one of the most successful open-source projects without any professional structure underneath.

{{VLC}} is downloaded at an approximate monthly rate of 23 millions from the main website and that's not including third-party distributions (Linux)!

You can find more information on [http://en.wikipedia.org/wiki/VLC_media_player VLC on Wikipedia] or on this [[Main Page|wiki]].

The engine of VLC is '''libVLC''', and is used by '''VLMC'''.

=== VideoLAN Movie Creator ===
[[VLMC]] is a cross-platform non-linear video editing software based on libVLC technology. It was started as a final year student project at the French IT school [http://www.epitech.eu EPITECH].

[[VLMC]] currently awaits a transition to the current libvlc API and it's actual 1.0 release!

=== Summer of Code ===

If selected and developed, SoC projects for VLMC and VLC will be included in later releases.

All projects are covered by the GPL (v2+) or LGPL (v2.1+) licenses depending on the module.

== How to Start ==
=== Find an idea ===
First, you need to find an idea.

This current page gives you a list of ideas. Those ideas are '''NOT exhaustive''': you can bring your own idea! Some of the best ideas we've ever had were '''custom''' ideas!

=== Submit your idea ===
You need to submit your idea on the ''Google Summer of Code'' platform.

You should do so, very quickly, even before having finished compilation and the next steps, so that we can give you early feedback.

=== Compile libVLC or VLMC ===
This may sound trivial, but it's harder than many expect. See https://wiki.videolan.org/Category:Building/ for more informations.

You should come on [[IRC]] to get help to compile.

=== Provide a small patch ===
To demonstrate your skills, share a small patch with us. This will let you become familiar with [[Git]], in case you don't know it already and our process on [[Sending Patches VLC|merging patches]].

=== Let's get in touch ===

If you have a doubt, are not sure about anything or want clarification, please get in touch with us.

We have 3 major communication channels: Our [https://mailman.videolan.org/mailman/listinfo mailing-lists] to discuss patches and further development related topics. Furthermore, we have our [http://forum.videolan.org web forums] for VLC-related end-user support - a VLMC section will be created once the product is published. Finally, there is our IRC channel ''#videolan'' (for libVLC) and ''#vlmc'' on the ''Freenode'' network. It's open to any kind of discussion. Usage issues, questions how to compile VLC/VLMC, getting to know the fellow developers, etc.

VLMC is aiming at being fully cross platform, but drifted a bit from that goal. While most VLMC's code is cross platform, and can be easily built targeting platforms, some dependencies might prove more difficult to build or compose with VLMC.

'''Tasks to do''':
# Fix MLT cross compilation for Windows (This will most likely require patching directly inside MLT, all contributions must be sent upstream).
# Fix medialibrary code & build process on macOS (and potentially iOS). The medialibrary misses some platform specific code to be able to list all connected drives (hard drives & USB removable storage, mostly) along with filesystem browsing
# Update the documentation along the way
# Create jenkins build configuration to have nightly builds on jenkins.videolan.org & nightlies.videolan.org for all supported platforms

'''Requirements''': This project requires buildsystems/toolchains knowledge, basic system programming on macOS & Windows

''Proposed mentors: Hugo''

== Remote UI ==

We would like to have a way to use VLMC from a web browser. You can easily imagine having a nice, shiny & simple UI for minimal movie edition, which would go hand in hand with the cloud storage feature.

'''Tasks to do''':
This task aims toward the uncoupling of the rendering backend & UI, as the renderer will run server side, while the UI runs on the client side.

The idea is to be able to have a UI interacting with the renderer without having to be in the same process, or even machine.

'''Requirements''': This project requires '''C++''' and '''JS''' knowledge.

== libmicrodns refactoring ==

Our current mDNS discoverer is working, but is not so respectful of the RFC.
Possible improvements include:
* Device TTL support
* Device removal detection
* Better request pacing
* Delegate socket interactions to the caller
* Unit testing
* Fuzzing

'''Requirements''': This project require '''C''' knowledge, as well as system programming skills

''Proposed mentor'': chouquette, tguillem

== libdsm SMBv2/3 support ==

libdsm works great for SMBv1, but doesn't support later version of the protocol. This will become a problem soon, and we need to fix it.

Possible improvements include:
* SMBv2 support
* SMBv3 support
* Unit testing
* Fuzzing

'''Requirements''': This project require '''C''' knowledge, as well as system programming skills

Chouquette: /* Summer of Code */

{{DISPLAYTITLE:Google Summer of Code 2018}}


https://developers.google.com/open-source/gsoc/images/gsoc2016-sun-373x373.png


This page summarize the current list of ideas for VideoLAN project, for [https://summerofcode.withgoogle.com Google Summer Of Code 2018].

The list is not exhaustive, and is not limitative. Feel free to apply with '''your own idea!'''

== Introduction & Information ==
[[File:Asterix VLC.svg|frameless|right]]

This wiki page covers the attempt by the [[VideoLAN]] project to act as a mentoring organization for [http://code.google.com/soc/ Google Summer of Code], in order to improve [[VLMC]] and [[VLC]] (or the [[libVLC]] engine).

=== Summer of Code ===

Google Summer of Code is a way for '''university students''' to have a paid '''internship''' by '''Google''' to work on open source projects and become top developers!

[[VideoLAN]] was a ''Google Summer of Code'' mentoring organization in [[SoC 2007|2007]], [[SoC 2008|2008]], [[SoC 2009|2009]], [[SoC 2010|2010]], [[SoC 2011|2011]], [[SoC 2013|2013]], [[SoC 2016|2016]] and [[Soc 2017|2017]].

This page list some ideas for Summer of Code projects on VLMC, libVLC and {{VLC}}.

=== VLC & libVLC ===

{{VLC}} is a cross-platform multimedia player, encoder and streamer application. It is one of the most successful open-source projects without any professional structure underneath.

{{VLC}} is downloaded at an approximate monthly rate of 23 millions from the main website and that's not including third-party distributions (Linux)!

You can find more information on [http://en.wikipedia.org/wiki/VLC_media_player VLC on Wikipedia] or on this [[Main Page|wiki]].

The engine of VLC is '''libVLC''', and is used by '''VLMC'''.

=== VideoLAN Movie Creator ===
[[VLMC]] is a cross-platform non-linear video editing software based on libVLC technology. It was started as a final year student project at the French IT school [http://www.epitech.eu EPITECH].

[[VLMC]] currently awaits a transition to the current libvlc API and it's actual 1.0 release!

=== Summer of Code ===

If selected and developed, SoC projects for VLMC and VLC will be included in later releases.

All projects are covered by the GPL (v2+) or LGPL (v2.1+) licenses depending on the module.

== How to Start ==
=== Find an idea ===
First, you need to find an idea.

This current page gives you a list of ideas. Those ideas are '''NOT exhaustive''': you can bring your own idea! Some of the best ideas we've ever had were '''custom''' ideas!

=== Submit your idea ===
You need to submit your idea on the ''Google Summer of Code'' platform.

You should do so, very quickly, even before having finished compilation and the next steps, so that we can give you early feedback.

=== Compile libVLC or VLMC ===
This may sound trivial, but it's harder than many expect. See https://wiki.videolan.org/Category:Building/ for more informations.

You should come on [[IRC]] to get help to compile.

=== Provide a small patch ===
To demonstrate your skills, share a small patch with us. This will let you become familiar with [[Git]], in case you don't know it already and our process on [[Sending Patches VLC|merging patches]].

=== Let's get in touch ===

If you have a doubt, are not sure about anything or want clarification, please get in touch with us.

We have 3 major communication channels: Our [https://mailman.videolan.org/mailman/listinfo mailing-lists] to discuss patches and further development related topics. Furthermore, we have our [http://forum.videolan.org web forums] for VLC-related end-user support - a VLMC section will be created once the product is published. Finally, there is our IRC channel ''#videolan'' (for libVLC) and ''#vlmc'' on the ''Freenode'' network. It's open to any kind of discussion. Usage issues, questions how to compile VLC/VLMC, getting to know the fellow developers, etc.

= Ideas for VLC & libVLC =

== libVLC AirPlay support ==

'''Project Description''':
libVLC is now able to send video to the ChromeCast devices. We want to be able to do the same using the Airplay protocol, for Apple devices.

We want to be able to cast from any device, including Android or Windows machines, on all support Airplay devices, like Apple TV, iOS devices and audio amplificators.

This will use the new renderer APIs added in libVLC 3.0. Those APIs will need to be extended to allow the renderer to kick in during the playback.

'''Tasks to do''':
The work will consist of the following tasks:
* documentation on the [https://nto.github.io/AirPlay.html AirPlay protocol],
* documentation on the '''RAOP''' VLC module,
* implementation of the detection/discovery of the supported devices,
* implementation of the protocol to discuss with the device,
* modify the device control in order to transcode on demand,
* polish and release.

'''Advice'''
Please have a look at the following files: {{file|modules/stream_out/chromecast/chromecast_ctrl.cpp|Chromecast}} {{file|include/vlc_renderer_discovery.h|renderer API}}
A motivated and fast enough student could pair this task with the UPnP renderer!

'''Requirements''':
This project requires '''C''' knowledge and access to some Airplay devices.

''Proposed mentor: steve''

=== Bonus: AirPlay target ===

See https://trac.videolan.org/vlc/ticket/5752

== libVLC UPnP renderer support ==

'''Project Description''':
libVLC is now able to send video to the ChromeCast devices. We want to be able to do the same using the UPnP Renderer protocol, for all the connected TV devices that support this protocol.

We want to be able to do that from any device, including Android, iOS or Windows machines.

This will use the new renderer APIs added in libVLC 3.0. Those APIs will need to be extended to allow the renderer to kick in during the playback.

'''Tasks to do''':
The work will consist of the following tasks:
* documentation on the [http://upnp.org/resources/documents/UPnP_AV_tutorial_July2014.pdf UPnP renderer] protocol and on the libupnp APIs,
* implementation of the detection/discovery of the supported devices,
* implementation of the protocol to discuss with the device,
* modify the control of the device in order to transcode on demand,
* polish and release.

'''Advice''':
Please have a look at the following files: {{file|modules/stream_out/chromecast/chromecast_ctrl.cpp|Chromecast}} {{file|include/vlc_renderer_discovery.h|renderer API}}

'''Requirements''':
This project requires '''C''' knowledge and access to some connected TV supporting this protocol.

''Proposed mentor: tguillem''

== Advanced Audio Filters ==

'''Project Description''':
We are looking for a skilled audiophile that knows a lot about audio theory and practice to work on new audio filters for VLC.

'''Tasks to do''':
* SRS WoW like or other 3D effects;
* channels mixing, notably upmixing, like Prologic-II;
* tracks mixing, and transitions;
* scriptable new audio filters in lua and enable users to create whatever audio filtering function they want in a Lua script;
* LADSPA or other libraries integration.

'''Requirements''':
This project needs some good audio knowledge and good C experience.

'''Qualification task:'''
Port any audio filter from MPlayer

''Proposed mentor: geal ''

== libVLC VR support ==
'''Project Description''':
libVLC is able to play most 2D and 360 videos, but the support of VR is very limited.

Because of 360 and VR support, the attention about '''VR''' is getting very popular those days. We need to support that in libVLC, with an Oculus, a Vive, or a similar headset.

'''Tasks to do''':
* understand the different types of 360, 360-stereo, VR movie types and the different headsets types,
* integrate a new headset view in a libvlccore module,
* integrate a new headset control in a libvlccore module, to get rotation,
* integrate the control UI with the headset,
* optionaly code a VR theater mode inside the OpenGL or D3D module.

'''Requirements''':
This project requires '''C''' knowledge and access to a VR headset.

''Proposed mentor: adrien''

== VLC Qt interface redesign ==
'''Project Description''':
The VLC interface is quite outdated on Linux and Windows. It has a lot of features, but some are not properly exposed.

This project for the summer is to rework heavily this interface to make it beautiful and useful again.

'''Scope of the tasks to do''':

The idea is to get closer to what the WinRT/UWP interface looks like ''(search on google image to get an idea)'', but other ideas are welcome.

The WinRT interface is simpler, more user friendly, and has a better "media center" feel into it.

It would require integration with the media library and with the current interface.

Qml is the preferred way of improving the current UI.

'''Requirements''':
This project requires '''Qt/C++''' knowledge.

''Proposed mentor: J-B''

== VLC macOS interface redesign ==
'''Project Description''':
The VLC interface is quite outdated on macOS.

This project for the summer is to rework heavily this interface to make it beautiful and useful again.

'''Scope of the tasks to do''':

The idea is to get closer to what the Apple TV/iOS interface looks like ''(search on google image to get an idea)'', but other ideas are welcome.

The iOS/AppleTV interface is simpler, more user friendly, and has a better "media center" feel into it.

It would require integration with the media library and with the current interface.

Starting from the current UI is a requirement.

'''Requirements''':
This project requires '''Obj-C''' knowledge.

''Proposed mentor: David F''

== VLC cryptographic updates ==
'''Project Description''':
VLC is already using '''GPG signatures''' to achieve secure updates on the Windows platform.

But the updates are currently signed
with a single master key which is pinned into the source code and VLCs in the wild aren't able to check for revocations of this key.

'''Tasks to do''':

Therefore we would like to improve this situation by:

* being able to sign developers' keys that can sign VLC binaries on behalf of this master key
* support revocations of these developer's key
* provide a master key upgrade path

'''Requirements''':
This project requires solid notions of '''C and Crypto'''.

''Proposed mentor: geal''

== Move VLC build system to Meson Build ==
'''Project Description''':
VLC Currently uses autotools but using Meson would make it easier to use it with IDEs and use a more modern language.

This project for the summer is to build the core VLC, its modules and libvlc with Meson Build on Linux, Windows, MacOS and possibly Android, iOS and Universal Windows.

'''Scope of the tasks to do''':

Building VLC can be tricky because of all the dependencies and reliance on autotools. Using a meta-build system like [http://mesonbuild.com/ Meson Build] would make things easier. Because we support a lot of platforms it can also be tricky to handle all the configurations where VLC can be built.

Integration in XCode and Visual Studio should help with such a meta-build system. It would also help the integration of other languages like Rust in the whole project.

Building some of the contribs with Meson Build would be a good plus.

'''Requirements''':
This project requires '''Python''', '''autotools''' and '''bash''' knowledge.

''Proposed mentor: Steve Lhomme''

== GPU shader filters ==
'''Project Description''':
VLC is using OpenGL and Direct3D11 on modern machines. It is now possible to do all kinds of video processing that was done in the CPU directly in the GPU.

This project for the summer is to port some of the existing CPU filters to the GPU using shaders.

'''Scope of the tasks to do''':

The first task will be to identify all the video filters in VLC and identify the ones that could be done as shaders. Then implement them. Either in OpenGL shaders, Direct3D11 shaders, both and maybe Vulkan.

'''Requirements''':
This project requires '''OpenGL''' or '''Direct3D11''' shaders knowledge as well as knowledge on video filters in general.

''Proposed mentor: Steve Lhomme''

= Ideas for VLMC =

== Port to Android ==

'''Project Description''':
VLMC is now working on the desktop. It would be nice to port it also to the mobile world, starting by Android.

This project would require to adapt to smaller screens, and simplify the UI to fit the Android workflow.

'''Tasks to do''':
# Fix the VLMC build for Android. As libVLC works fine on Android, this is more focused on compiling the Qt part for Android.
# Split more parts of the UI in components that are reusable on mobile.
# Change the components to fit the small resolutions of the Android devices.
# Rewrite some UI components in QML.
# Write a simpler timeline widget for Mobile workflows.

'''Requirements''': This project requires '''C++/Qt/qml''' knowledge, and access to Android devices.

''Proposed mentors: Geoffrey/Hugo''

== Port to iOS ==

'''Project Description''':
VLMC is now working on the desktop. It would be nice to port it also to the mobile world, also on iOS.

This project would require to adapt to smaller screens, and simplify the UI to fit the iOS workflow.

'''Tasks to do''':

'''Requirements''': This project requires '''C++/Qt/qml''' knowledge, and access to Android devices.

''Proposed mentors: Felix/Hugo''

== Media Workflow rework ==

'''Project Description''':
VLMC is now working on the desktop, but the media workflow is quite slow and is missing some common use cases.

This should be fixed in [https://github.com/mltframework/mlt MLT] framework backend for libVLC and is the continuation from the work from the previous Summer of Code.

'''Tasks to do''':
# Understand the MLT libVLC backend codebase,
# Clean the backend and port it to a cleaner code state in C++,
# Benchmark the code and make it more efficient,
# Work to merge this backend upstream,
# Implement all the missing features in libVLC.

'''Requirements''': This project requires '''C/C++''' knowledge, and understanding of multimedia concepts is a good positive point.

''Proposed mentors: Hugo''

== Workflow audio filters ==

'''Project Description''':
VLMC is now working on the desktop, but we need to have a good setup of audio filters to make it usable for most people.

'''Tasks to do''':
# Understand the VLMC and MLT codebase interactions,
# Add audio filters on the MLT framework backend using the [https://en.wikipedia.org/wiki/LADSPA LADSPA]/[http://lv2plug.in/ LV2] library or a similar open source library,

This project for the summer is to rework heavily this interface to make it beautiful and useful again.

'''Scope of the tasks to do''':

The idea is to get closer to what the Apple TV/iOS interface looks like ''(search on google image to get an idea)'', but other ideas are welcome.

The iOS/AppleTV interface is simpler, more user friendly, and has a better "media center" feel into it.

It would require integration with the media library and with the current interface.

Starting from the current UI is a requirement.

'''Requirements''':
This project requires '''Obj-C''' knowledge.

== VLC cryptographic updates ==
'''Project Description''':
VLC is already using '''GPG signatures''' to achieve secure updates on the Windows platform.

But the updates are currently signed
with a single master key which is pinned into the source code and VLCs in the wild aren't able to check for revocations of this key.

'''Tasks to do''':

Therefore we would like to improve this situation by:

* being able to sign developers' keys that can sign VLC binaries on behalf of this master key
* support revocations of these developer's key
* provide a master key upgrade path

'''Requirements''':
This project requires solid notions of '''C and Crypto'''.

'''Project Description''':
VLMC is now working on the desktop. It would be nice to port it also to the mobile world, starting by Android.

This project would require to adapt to smaller screens, and simplify the UI to fit the Android workflow.

'''Tasks to do''':
# Fix the VLMC build for Android. As libVLC works fine on Android, this is more focused on compiling the Qt part for Android.
# Split more parts of the UI in components that are reusable on mobile.
# Change the components to fit the small resolutions of the Android devices.
# Rewrite some UI components in QML.
# Write a simpler timeline widget for Mobile workflows.

== Media Workflow rework ==

'''Project Description''':
VLMC is now working on the desktop, but the media workflow is quite slow and is missing some common use cases.

This should be fixed in [https://github.com/mltframework/mlt MLT] framework backend for libVLC and is the continuation from the work from the previous Summer of Code.

'''Tasks to do''':
# Understand the MLT libVLC backend codebase,
# Clean the backend and port it to a cleaner code state in C++,
# Benchmark the code and make it more efficient,
# Work to merge this backend upstream,
# Implement all the missing features in libVLC.

'''Requirements''': This project requires '''C/C++''' knowledge, and understanding of multimedia concepts is a good positive point.

''Proposed mentors: Hugo''

== Workflow audio filters ==

'''Project Description''':
VLMC is now working on the desktop, but we need to have a good setup of audio filters to make it usable for most people.

'''Tasks to do''':
# Understand the VLMC and MLT codebase interactions,
# Add audio filters on the MLT framework backend using the [https://en.wikipedia.org/wiki/LADSPA LADSPA]/[http://lv2plug.in/ LV2] library or a similar open source library,
# Code the interface corresponding to those filters, and their options,
# Prepare visualizations, and notably for soundwave filters,
# Integrate those inside the timeline UI,
# Optimize.

'''Requirements''': This project requires '''C++/Qt/qml''' knowledge, and enough understanding of audio.

''Proposed mentors: J-B''

== Workflow video filters ==

'''Project Description''':
VLMC is now working on the desktop, but we need to have a good setup of video filters to make it usable for most people.

'''Tasks to do''':
# Understand the VLMC and MLT codebase interactions,
# Add video filters on the MLT framework backend using the [https://git.sesse.net/?p=movit;a=summary movit] library or a similar open source library,
# Code the interface corresponding to those filters, and their options,
# Add transitions between clips
# Code the interface to manage those transitions,
# Optimize the code.

'''Requirements''': This project requires '''C/C++''' knowledge.

''Proposed mentors: Felix''

== Improve multiplatform support ==
VLMC is aiming at being fully cross platform, but drifted a bit from that goal. While most VLMC's code is cross platform, and can be easily built targeting platforms, some dependencies might prove more difficult to build or compose with VLMC.

'''Tasks to do''':
# Fix MLT cross compilation for Windows (This will most likely require patching directly inside MLT, all contributions must be sent upstream).
# Fix medialibrary code & build process on macOS (and potentially iOS). The medialibrary misses some platform specific code to be able to list all connected drives (hard drives & USB removable storage, mostly) along with filesystem browsing
# Update the documentation along the way
# Create jenkins build configuration to have nightly builds on jenkins.videolan.org & nightlies.videolan.org for all supported platforms

'''Requirements''': This project requires buildsystems/toolchains knowledge, basic system programming on macOS & Windows

''Proposed mentors: Hugo''

== Remote UI ==

We would like to have a way to use VLMC from a web browser. You can easily imagine having a nice, shiny & simple UI for minimal movie edition, which would go hand in hand with the cloud storage feature.

'''Tasks to do''':
This task aims toward the uncoupling of the rendering backend & UI, as the renderer will run server side, while the UI runs on the client side.

The idea is to be able to have a UI interacting with the renderer without having to be in the same process, or even machine.

'''Requirements''': This project requires '''C++''' and '''JS''' knowledge.

{{DISPLAYTITLE:Google Summer of Code 2018}}


https://developers.google.com/open-source/gsoc/images/gsoc2016-sun-373x373.png


This page summarize the current list of ideas for VideoLAN project, for [https://summerofcode.withgoogle.com Google Summer Of Code 2018].

The list is not exhaustive, and is not limitative. Feel free to apply with '''your own idea!'''

== Introduction & Information ==
[[File:Asterix VLC.svg|frameless|right]]

This wiki page covers the attempt by the [[VideoLAN]] project to act as a mentoring organization for [http://code.google.com/soc/ Google Summer of Code], in order to improve [[VLMC]] and [[VLC]] (or the [[libVLC]] engine).

=== Summer of Code ===

Google Summer of Code is a way for '''university students''' to have a paid '''internship''' by '''Google''' to work on open source projects and become top developers!

[[VideoLAN]] was a ''Google Summer of Code'' mentoring organization in [[SoC 2007|2007]], [[SoC 2008|2008]], [[SoC 2009|2009]], [[SoC 2010|2010]], [[SoC 2011|2011]], [[SoC 2013|2013]] and [[SoC 2016|2016]].

This page list some ideas for Summer of Code projects on VLMC, libVLC and {{VLC}}.

=== VLC & libVLC ===

{{VLC}} is a cross-platform multimedia player, encoder and streamer application. It is one of the most successful open-source projects without any professional structure underneath.

{{VLC}} is downloaded at an approximate monthly rate of 23 millions from the main website and that's not including third-party distributions (Linux)!

You can find more information on [http://en.wikipedia.org/wiki/VLC_media_player VLC on Wikipedia] or on this [[Main Page|wiki]].

The engine of VLC is '''libVLC''', and is used by '''VLMC'''.

=== VideoLAN Movie Creator ===
[[VLMC]] is a cross-platform non-linear video editing software based on libVLC technology. It was started as a final year student project at the French IT school [http://www.epitech.eu EPITECH].

[[VLMC]] currently awaits a transition to the current libvlc API and it's actual 1.0 release!

=== Summer of Code ===

If selected and developed, SoC projects for VLMC and VLC will be included in later releases.

All projects are covered by the GPL (v2+) or LGPL (v2.1+) licenses depending on the module.

== How to Start ==
=== Find an idea ===
First, you need to find an idea.

This current page gives you a list of ideas. Those ideas are '''NOT exhaustive''': you can bring your own idea! Some of the best ideas we've ever had were '''custom''' ideas!

=== Submit your idea ===
You need to submit your idea on the ''Google Summer of Code'' platform.

You should do so, very quickly, even before having finished compilation and the next steps, so that we can give you early feedback.

=== Compile libVLC or VLMC ===
This may sound trivial, but it's harder than many expect. See https://wiki.videolan.org/Category:Building/ for more informations.

You should come on [[IRC]] to get help to compile.

=== Provide a small patch ===
To demonstrate your skills, share a small patch with us. This will let you become familiar with [[Git]], in case you don't know it already and our process on [[Sending Patches VLC|merging patches]].

=== Let's get in touch ===

If you have a doubt, are not sure about anything or want clarification, please get in touch with us.

We have 3 major communication channels: Our [https://mailman.videolan.org/mailman/listinfo mailing-lists] to discuss patches and further development related topics. Furthermore, we have our [http://forum.videolan.org web forums] for VLC-related end-user support - a VLMC section will be created once the product is published. Finally, there is our IRC channel ''#videolan'' (for libVLC) and ''#vlmc'' on the ''Freenode'' network. It's open to any kind of discussion. Usage issues, questions how to compile VLC/VLMC, getting to know the fellow developers, etc.

= Ideas for VLC & libVLC =

== libVLC AirPlay support ==

'''Project Description''':
libVLC is now able to send video to the ChromeCast devices. We want to be able to do the same using the Airplay protocol, for Apple devices.

We want to be able to cast from any device, including Android or Windows machines, on all support Airplay devices, like Apple TV, iOS devices and audio amplificators.

This will use the new renderer APIs added in libVLC 3.0. Those APIs will need to be extended to allow the renderer to kick in during the playback.

'''Tasks to do''':
The work will consist of the following tasks:
* documentation on the [https://nto.github.io/AirPlay.html AirPlay protocol],
* documentation on the '''RAOP''' VLC module,
* implementation of the detection/discovery of the supported devices,
* implementation of the protocol to discuss with the device,
* modify the device control in order to transcode on demand,
* polish and release.

'''Advice'''
Please have a look at the following files: {{file|modules/stream_out/chromecast/chromecast_ctrl.cpp|Chromecast}} {{file|include/vlc_renderer_discovery.h|renderer API}}
A motivated and fast enough student could pair this task with the UPnP renderer!

'''Requirements''':
This project requires '''C''' knowledge and access to some Airplay devices.

''Proposed mentor: steve''

=== Bonus: AirPlay target ===

See https://trac.videolan.org/vlc/ticket/5752

== libVLC UPnP renderer support ==

'''Project Description''':
libVLC is now able to send video to the ChromeCast devices. We want to be able to do the same using the UPnP Renderer protocol, for all the connected TV devices that support this protocol.

We want to be able to do that from any device, including Android, iOS or Windows machines.

This will use the new renderer APIs added in libVLC 3.0. Those APIs will need to be extended to allow the renderer to kick in during the playback.

'''Tasks to do''':
The work will consist of the following tasks:
* documentation on the [http://upnp.org/resources/documents/UPnP_AV_tutorial_July2014.pdf UPnP renderer] protocol and on the libupnp APIs,
* implementation of the detection/discovery of the supported devices,
* implementation of the protocol to discuss with the device,
* modify the control of the device in order to transcode on demand,
* polish and release.

'''Advice''':
Please have a look at the following files: {{file|modules/stream_out/chromecast/chromecast_ctrl.cpp|Chromecast}} {{file|include/vlc_renderer_discovery.h|renderer API}}
A motivated and fast enough student could pair this task with the Airplay renderer!

'''Requirements''':
This project requires '''C''' knowledge and access to some connected TV supporting this protocol.

''Proposed mentor: tguillem''

== Advanced Audio Filters ==

'''Project Description''':
We are looking for a skilled audiophile that knows a lot about audio theory and practice to work on new audio filters for VLC.

'''Tasks to do''':
* SRS WoW like or other 3D effects;
* channels mixing, notably upmixing, like Prologic-II;
* tracks mixing, and transitions;
* scriptable new audio filters in lua and enable users to create whatever audio filtering function they want in a Lua script;
* LADSPA or other libraries integration.

'''Requirements''':
This project needs some good audio knowledge and good C experience.

'''Qualification task:'''
Port any audio filter from MPlayer

''Proposed mentor: geal ''

== libVLC VR support ==
'''Project Description''':
libVLC is able to play most 2D and 360 videos, but the support of VR is very limited.

Because of 360 and VR support, the attention about '''VR''' is getting very popular those days. We need to support that in libVLC, with an Oculus, a Vive, or a similar headset.

'''Tasks to do''':
* understand the different types of 360, 360-stereo, VR movie types and the different headsets types,
* integrate a new headset view in a libvlccore module,
* integrate a new headset control in a libvlccore module, to get rotation,
* integrate the control UI with the headset,
* optionaly code a VR theater mode inside the OpenGL or D3D module.

'''Requirements''':
This project requires '''C''' knowledge and access to a VR headset.

== VLC Qt interface redesign ==
'''Project Description''':
The VLC interface is quite outdated on Linux and Windows. It has a lot of features, but some are not properly exposed.

This project for the summer is to rework heavily this interface to make it beautiful and useful again.

'''Scope of the tasks to do''':

The idea is to get closer to what the WinRT/UWP interface looks like ''(search on google image to get an idea)'', but other ideas are welcome.

The WinRT interface is simpler, more user friendly, and has a better "media center" feel into it.

It would require integration with the media library and with the current interface.

Qml is the preferred way of improving the current UI.

'''Requirements''':
This project requires '''Qt/C++''' knowledge.

''Proposed mentor: J-B''

== VLC macOS interface redesign ==
'''Project Description''':
The VLC interface is quite outdated on macOS.

This project for the summer is to rework heavily this interface to make it beautiful and useful again.

'''Scope of the tasks to do''':

The idea is to get closer to what the Apple TV/iOS interface looks like ''(search on google image to get an idea)'', but other ideas are welcome.

The iOS/AppleTV interface is simpler, more user friendly, and has a better "media center" feel into it.

It would require integration with the media library and with the current interface.

Starting from the current UI is a requirement.

'''Requirements''':
This project requires '''Obj-C''' knowledge.

== VLC cryptographic updates ==
'''Project Description''':
VLC is already using '''GPG signatures''' to achieve secure updates on the Windows platform.

But the updates are currently signed
with a single master key which is pinned into the source code and VLCs in the wild aren't able to check for revocations of this key.

'''Tasks to do''':

Therefore we would like to improve this situation by:

* being able to sign developers' keys that can sign VLC binaries on behalf of this master key
* support revocations of these developer's key
* provide a master key upgrade path

'''Requirements''':
This project requires solid notions of '''C and Crypto'''.

'''Requirements''': This project requires buildsystems/toolchains knowledge, basic system programming on macOS & Windows

''Proposed mentors: Hugo''

== Remote UI ==

We would like to have a way to use VLMC from a web browser. You can easily imagine having a nice, shiny & simple UI for minimal movie edition, which would go hand in hand with the cloud storage feature.

'''Tasks to do''':
This task aims toward the uncoupling of the rendering backend & UI, as the renderer will run server side, while the UI runs on the client side.

The idea is to be able to have a UI interacting with the renderer without having to be in the same process, or even machine.

VLC command-line help

2017-07-12T15:18:36Z

Chouquette: Reverting the revert. The original intent was to go back to an earlier version to fix a log, that didn't work too well. Sorry about that

:''See also [[Command line]], [[Console|Console interfaces]]''
Running the command
vlc --help
will create a .TXT file containing all the command-line options.

You can also use this to get more exhaustive list:
vlc -H

If you look for help, on a particular module, you can also use
vlc -p module --advanced

To view this without leaving the command-line in Windows, use the following command (assuming you installed it in the default folder):
more "C:\Program Files\VideoLAN\VLC\vlc-help.txt"
This trick uses the command-line command <code>more</code> to show the file screen-by-screen. Pressing spacebar will advance the output a screen at a time, and pressing enter will advance the output one line at a time.

Undocumented option:
<pre style="white-space: pre-wrap;"><nowiki>-vv "Verbose verbose". Verbose output (debug infos can be displayed by selecting "Debug logging" interface under View->Add Interface menu)</nowiki></pre>

Here's the output of ''vlc -H'' of the stable 2.1.3 under Windows. If you are looking for 0.8.6 help, go [[VLC-0-8-6_command-line_help]]. If you are looking for 0.9.x help, go [[VLC-0-9-x_command-line_help]]. If you are looking for 1.0.x help, go [[VLC-1-0-x_command-line_help]]. If you are looking for 1.1.x help, go [[VLC-1-1-x_command-line_help]]
Note: This has been formatted for enhanced readability.

<pre style="white-space: pre-wrap;"><nowiki>
Usage: vlc [options] [stream] ...
You can specify multiple streams on the commandline.
They will be enqueued in the playlist.
The first item specified will be played first.

Options-styles:
--option A global option that is set for the duration of the program.
-option A single letter version of a global --option.
:option An option that only applies to the stream directly before it
and that overrides previous settings.

Stream MRL syntax:
[[access][/demux]://]URL[#[title][:chapter][-[title][:chapter]]]
[:option=value ...]

Many of the global --options can also be used as MRL specific :options.
Multiple :option=value pairs can be specified.

URL syntax:
file:///path/file Plain media file
http://host[:port]/file HTTP URL
ftp://host[:port]/file FTP URL
mms://host[:port]/file MMS URL
screen:// Screen capture
dvd://[device] DVD device

--sout-x264-keyint=<integer [-2147483648 .. 2147483647]>
Maximum GOP size
Sets maximum interval between IDR-frames.Larger values save bits, thus improving quality for a given bitrate at the cost of seeking precision. Use -1 for infinite.
--sout-x264-min-keyint=<integer [-2147483648 .. 2147483647]>
Minimum GOP size
Sets minimum interval between IDR-frames. In H.264, I-frames do not necessarily bound a closed GOP because it is allowable for a P-frame to be predicted from more frames than just the one frame before it (also see reference frame option). Therefore, I-frames are not necessarily seekable. IDR-frames restrict subsequent P-frames from referring to any frame prior to the IDR-frame. If scenecuts appear within this interval, they are still encoded as I-frames, but do not start a new GOP.

--sout-x264-scenecut=<integer [-1 .. 100]>
Extra I-frames aggressivity
Scene-cut detection. Controls how aggressively to insert extra I-frames. With small values of scenecut, the codec often has to force an I-frame when it would exceed keyint. Good values of scenecut may find a better location for the I-frame. Large values use more I-frames than necessary, thus wasting bits. -1 disables scene-cut detection, so I-frames are inserted only every other keyint frames, which probably leads to ugly encoding artifacts. Range 1 to 100.

VLC command-line help

2017-07-12T15:07:08Z

Chouquette: Undo revision 33404 by Ninja (talk)

:''See also [[Command line]], [[Console|Console interfaces]]''
Running the command
vlc --help
will create a .TXT file containing all the command-line options.

You can also use this to get more exhaustive list:
vlc -H

If you look for help, on a particular module, you can also use
vlc -p module --advanced

To view this without leaving the command-line in Windows, use the following command (assuming you installed it in the default folder):
more "C:\Program Files\VideoLAN\VLC\vlc-help.txt"
This trick uses the command-line command <code>more</code> to show the file screen-by-screen. Pressing spacebar will advance the output a screen at a time, and pressing enter will advance the output one line at a time.

Undocumented option:
<pre style="white-space: pre-wrap;"><nowiki>-vv "Verbose verbose". Verbose output (debug infos can be displayed by selecting "Debug logging" interface under View->Add Interface menu)</nowiki></pre>

Here's the output of ''vlc -H'' of the stable 2.1.3 under Windows. If you are looking for 0.8.6 help, go [[VLC-0-8-6_command-line_help]]. If you are looking for 0.9.x help, go [[VLC-0-9-x_command-line_help]]. If you are looking for 1.0.x help, go [[VLC-1-0-x_command-line_help]]. If you are looking for 1.1.x help, go [[VLC-1-1-x_command-line_help]]
Note: This has been formatted for enhanced readability.

<pre style="white-space: pre-wrap;"><nowiki>
Usage: vlc [options] [stream] ...
You can specify multiple streams on the commandline.
They will be enqueued in the playlist.

Options-styles:
--option A global option that is set for the duration of the program.
-option A single letter version of a global --option.
:option An option that only applies to the stream directly before it
and that overrides previous settings.

Stream MRL syntax:
[[access][/demux]://]URL[#[title][:chapter][-[title][:chapter]]]
[:option=value ...]

Many of the global --options can also be used as MRL specific :options.
Multiple :option=value pairs can be specified.

URL syntax:
file:///path/file Plain media file
http://host[:port]/file HTTP URL
ftp://host[:port]/file FTP URL
mms://host[:port]/file MMS URL
screen:// Screen capture
dvd://[device] DVD device
vcd://[device] VCD device
cdda://[device] Audio CD device

--sout-x264-keyint=<integer [-2147483648 .. 2147483647]>
Maximum GOP size
Sets maximum interval between IDR-frames.Larger values save bits, thus improving quality for a given bitrate at the cost of seeking precision. Use -1 for infinite.
--sout-x264-min-keyint=<integer [-2147483648 .. 2147483647]>
Minimum GOP size
Sets minimum interval between IDR-frames. In H.264, I-frames do not necessarily bound a closed GOP because it is allowable for a P-frame to be predicted from more frames than just the one frame before it (also see reference frame option). Therefore, I-frames are not necessarily seekable. IDR-frames restrict subsequent P-frames from referring to any frame prior to the IDR-frame. If scenecuts appear within this interval, they are still encoded as I-frames, but do not start a new GOP.

--sout-x264-scenecut=<integer [-1 .. 100]>
Extra I-frames aggressivity
Scene-cut detection. Controls how aggressively to insert extra I-frames. With small values of scenecut, the codec often has to force an I-frame when it would exceed keyint. Good values of scenecut may find a better location for the I-frame. Large values use more I-frames than necessary, thus wasting bits. -1 disables scene-cut detection, so I-frames are inserted only every other keyint frames, which probably leads to ugly encoding artifacts. Range 1 to 100.

VLC command-line help

2017-07-11T18:12:32Z

Chouquette: Improve readability & a few grammar/punctuation fixes - courtesy of ninja_kirby@hotmail.com

:''See also [[Command line]], [[Console|Console interfaces]]''
Running the command
vlc --help
will create a .TXT file containing all the command-line options.

You can also use this to get more exhaustive list:
vlc -H

If you look for help, on a particular module, you can also use
vlc -p module --advanced

To view this without leaving the command-line in Windows, use the following command (assuming you installed it in the default folder):
more "C:\Program Files\VideoLAN\VLC\vlc-help.txt"
This trick uses the command-line command <code>more</code> to show the file screen-by-screen. Pressing spacebar will advance the output a screen at a time, and pressing enter will advance the output one line at a time.

Undocumented option:
<pre style="white-space: pre-wrap;"><nowiki>-vv "Verbose verbose". Verbose output (debug infos can be displayed by selecting "Debug logging" interface under View->Add Interface menu)</nowiki></pre>

Here's the output of ''vlc -H'' of the stable 2.1.3 under Windows. If you are looking for 0.8.6 help, go [[VLC-0-8-6_command-line_help]]. If you are looking for 0.9.x help, go [[VLC-0-9-x_command-line_help]]. If you are looking for 1.0.x help, go [[VLC-1-0-x_command-line_help]]. If you are looking for 1.1.x help, go [[VLC-1-1-x_command-line_help]]
Note: This has been formatted for enhanced readability.

<pre style="white-space: pre-wrap;"><nowiki>

--sout-x264-keyint=<integer [-2147483648 .. 2147483647]>
Maximum GOP size
Sets maximum interval between IDR-frames.Larger values save bits, thus improving quality for a given bitrate at the cost of seeking precision. Use -1 for infinite.
--sout-x264-min-keyint=<integer [-2147483648 .. 2147483647]>
Minimum GOP size
Sets minimum interval between IDR-frames. In H.264, I-frames do not necessarily bound a closed GOP because it is allowable for a P-frame to be predicted from more frames than just the one frame before it (also see reference frame option). Therefore, I-frames are not necessarily seekable. IDR-frames restrict subsequent P-frames from referring to any frame prior to the IDR-frame. If scenecuts appear within this interval, they are still encoded as I-frames, but do not start a new GOP.
--sout-x264-opengop, --no-sout-x264-opengop

--sout-x264-scenecut=<integer [-1 .. 100]>
Extra I-frames aggressivity
Scene-cut detection. Controls how aggressively to insert extra I-frames. With small values of scenecut, the codec often has to force an I-frame when it would exceed keyint. Good values of scenecut may find a better location for the I-frame. Large values use more I-frames than necessary, thus wasting bits. -1 disables scene-cut detection, so I-frames are inserted only every other keyint frames, which probably leads to ugly encoding artifacts. Range 1 to 100.
--sout-x264-bframes=<integer [0 .. 16]>
B-frames between I and P
Number of consecutive B-frames between I and P-frames. Range 1 to 16.

Win32Compile

2017-03-21T13:48:58Z

Chouquette: /* Configure */

This page will help you to compile {{VLC}} for [[Windows]].

== Building Methods ==

If you want to build VLC from source, you have several choices:

{| class="wikitable"
|-
! Method
! Documentation
! Notes
|-
| '''MinGW on Linux'''
| [[Win32Compile#Obtaining_the_toolchain|Obtaining the toolchain]]
| '''Preferred''' method involving cross-compilation from Linux. On computers running Microsoft Windows, a virtual machine is necessary to run Linux.
|-
| '''[http://www.mingw.org MSYS+MinGW]''' on Windows
| [[Win32CompileMSYS|Compile with MSys]]
| '''Native''' compilation method. MSYS is a minimal build environment to compile Unix-style projects directly on Microsoft Windows. This is '''not officially supported''' by VideoLAN. Best of luck.
|-
| '''Cygwin''' on Windows
| [[Win32CompileCygwinNew|Compile with Cygwin]]
| Cygwin method. Cygwin emulates a POSIX environment to compile on Microsoft Windows. This is '''error'''-prone and '''slow''' and therefore not recommended.
|}

== Obtaining the cross-compilation toolchain ==
All this howto is focused on '''Debian/Ubuntu'''. For other distribution, please find the related package names, but they should be very similar.

'''Ubuntu 14.04''' is too old to compile VLC.

=== Host triplet ===
A number of commands below include the toolchain identifier, called the ''host triplet''.

This value is '''essential''': it instructs the build system to use the correct toolchain and compile the program for Windows.
Without the value, the build system will perform a native compilation for Linux (or whatever your computer runs). With an incorrect value, the build will fail.

The exact value depends on your installation of the toolchain.

Notably on Debian/Ubuntu, these values must be used:
* ''i686-w64-mingw32'' for Windows 32-bits, using the Mingw-w64 toolchain
* ''x86_64-w64-mingw32'' for Windows 64-bits, using the Mingw-w64 toolchain

Please make sure that you replace the keywords ''HOST-TRIPLET'' with either ''i686-w64-mingw32'' or ''x86_64-w64-mingw32'' adapted to your target Windows version (32-bit or 64-bit, respectively)

=== Compiler and binary toolchain ===

==== Mingw-w64 ====
To compile VLC for Windows (32-bits or 64-bits), the Mingw-w64 toolchain is required:

For the 32-bit version, run this:
# apt-get install gcc-mingw-w64-i686 g++-mingw-w64-i686 mingw-w64-tools

For the 64-bit version, this becomes:
# apt-get install gcc-mingw-w64-x86-64 g++-mingw-w64-x86-64 mingw-w64-tools

'''NB:''' you need mingw-w64 version 5.0.1 to compile it.

=== Development tools ===
You will also need:
* lua (5.2)
* all autotools: libtool, automake, autoconf, autopoint, make, gettext, pkg-config
* qt4-dev-tools, qt5-default (or qt4-default if qt plugin build fails)
* git, subversion cmake, cvs if you want to rebuild contribs
* wine-dev for creating Win32 packages
* zip [for creating .zip package], p7zip [for .7z package], nsis [for .exe auto-installer], bzip2 [for 'make prebuild]

'''Run:'''
# apt-get install lua5.2 libtool automake autoconf autopoint make gettext pkg-config
# apt-get install qt4-dev-tools qt5-default git subversion cmake cvs
# apt-get install wine64-development-tools zip p7zip nsis bzip2
# apt-get install yasm ragel ant default-jdk protobuf-compiler dos2unix

== Get the source code ==
$ git clone http://git.videolan.org/git/vlc.git vlc

See [[Git]] for more information.

== Go into the VLC directory ==
$ cd vlc

== Prepare [[Contrib Status|3rd party libraries]] ==

VLC depends on a sizable number of third party libraries. Before compiling VLC, you need to obtain compiled versions of those. There are two ways to achieve that:
* The ''prebuilt'' approach is much faster and easier, but only works with a narrow set of VLC versions.
* The ''manual build'' approach takes a lot of time and disk space, and somewhat error-prone.

Please note that the prebuilt library versions are intended for the latest current ''stable release'' of VLC. It is not compatible with old VLC versions, nor with newer or future versions.

At the time of writing (late 2016), the prebuilt libraries work with VLC 2.2.x '''only'''. To compile the VLC 3.0.x development branch, '''DO NOT USE''' the prebuilt libraries.

=== Prebuilt (fast) ===
$ mkdir -p contrib/win32
$ cd contrib/win32
$ ../bootstrap --host=HOST-TRIPLET
$ make prebuilt

=== Manually built (slow) ===
Or, if you want to compile the contribs yourself and are feeling adventurous and have lots of time to burn:
# apt-get install subversion yasm cvs cmake ragel autopoint

$ mkdir -p contrib/win32
$ cd contrib/win32
$ ../bootstrap --host=HOST-TRIPLET
$ make fetch
$ make

=== Linux 64-bit ===

If you are on Linux '''64-bit''', you '''SHOULD''' remove some files, or install the lib32 packages (ia32-libs, multilibs, etc...)

$ rm -f ../i686-w64-mingw32/bin/moc ../i686-w64-mingw32/bin/uic ../i686-w64-mingw32/bin/rcc

=== Fix your contrib path ===

If your host triplet is not '''i686-w64-mingw32''' (you are ''not'' compiling for Debian or Ubuntu), create a symlink to contribs:
$ ln -sf ''''HOST-TRIPLET'''' ../i686-w64-mingw32
Notice that there is no <code>../</code> before the host triplet. This is intentional, and if done properly, you should see a functioning symbolic link created in the parent directory (try <code>ls -l ..</code> and you should see <code>i686-w64-mingw32 -> x86_64-w64-mingw32/</code>).

=== Go Back ===

Go back to the VLC source directory:

$ cd -

== Configuring the build ==

=== Bootstrap ===
First, prepare the tree:
$ ./bootstrap

=== Configure ===
Then you can to configure the build with the <code>./configure</code> script.

Create a subfolder:
$ mkdir win32 && cd win32

Set your PKG_CONFIG_LIBDIR (Adapt the path to reflect your local setup)
$ export PKG_CONFIG_LIBDIR=$HOME/vlc/contrib/HOST-TRIPLET/lib/pkgconfig
$ export PKG_CONFIG_PATH_CUSTOM=$PKG_CONFIG_LIBDIR (for Archlinux only)

Execute the build configuration script:
$ ../extras/package/win32/configure.sh --host=HOST-TRIPLET --build=x86_64-pc-linux-gnu

'''N.B.''':
Use the host and build tuples respectively corresponding to '''your''' cross-compilation toolchain and build system respectively. The example above assumes you are compiling for ''Windows'' OS and ''Intel 686'' architecture, and the build system is ''GNU/Linux'' OS and ''x86 64-bits'' architecture. See [[#Host_triplet|above]] for list of common values.

Also, if you have a problem here (such as an error about Library dvdread), see the [[Talk:Win32Compile|Talk]] page.

Alternatively, you can run configure manually:
$ ../configure --host=HOST-TRIPLET --build=x86_64-pc-linux-gnu
See <code>'../configure --help'</code> for more information.

== Building VLC ==

Once configured, to build VLC, just run:
$ make

== Packaging VLC ==
Once the compilation is done, you can build self-contained VLC packages with the following <code>make</code> rules:

{| class="wikitable"
|-
! Command
! Description
|-
| <code>make package-win-common</code>
| Creates a subdirectory named <code>vlc-x.x.x</code> with all the binaries. You can run VLC directly from this directory.
|-
| <code>make package-win-strip</code>
| Same as above but will create 'stripped' binaries (that is, smallest size, unusable with a debugger).
|-
| <code>make package-win32-7zip</code>
| Same as above but will package the directory in a 7z file.
|-
| <code>make package-win32-zip</code>
| Same as above but will package the directory in a zip file.
|-
| <code>make package-win32</code>
| Same as above but will also create an auto-installer package. You must have NSIS installed in its default location for this to work.
|}

'''''Well done—you're ready to use VLC!'''''

== Extra information ==

=== Static compilation of plugins ===
You might want to use the following script to enforce static compilation.
Run as root, and use at your own risk.

#!/bin/sh

# This script enforces statically linking of libgcc, libstdc++-6, and libpthread,
# without needing to rebuild gcc and mingw-w64 from scratch.
# -static-libgcc -static-libstdc++ flags can not be used in a libtool build system,
# as libtool removes flags that it doesn't understand.

move() {
[ -f $1 ] || return 1
mkdir -p old/
mv -v $* old/
return 0
}

for x in i686 x86_64
do
library_path_list=`$x-w64-mingw32-gcc -v /dev/null 2>&1 | grep ^LIBRARY_PATH|cut -d= -f2|sort|uniq`
IFS=':'
for i in $library_path_list
do
cd $i
move libstdc++-6.dll libstdc++.dll.a libgcc_s.a libgcc_s_sjlj-1.dll && ln -s libgcc_eh.a libgcc_s.a
move libpthread.dll.a libwinpthread.dll.a
move libwinpthread-1.dll
[ -d ../bin ] && cd ../bin && move libwinpthread-1.dll
done
done

exit 0

=== Mingw32 ===
Up to versions 2.0.x, VLC was compiled with the older mingw32 toolchain, which only supports 32-bits Windows. If you have problems with mingw-w64, you can try mingw32 instead:

* '''Debian/Ubuntu''': run <code>apt-get install gcc-mingw32 mingw32-binutils</code>. Note that at least version 3.17 of Mingw32 is required, which Debian does not provide. You may obtain mingw32-runtime-3.17 [http://people.videolan.org/~jb/debian/mingw32-runtime_3.17.0-0videolan_all.deb here].
* '''Gentoo''' users can <code>emerge crossdev && crossdev mingw32</code>
* '''ArchLinux''' users can <code>pacman -S mingw32-gcc</code>
* '''Fedora''' users should read [[Win32Compile Under Fedora]]
* Other '''Linux''' systems may attempt http://www.mingw.org/wiki/LinuxCrossMinGW

Chouquette: /* Ideas for VLMC */

{{DISPLAYTITLE:Google Summer of Code 2017}}

This page summarize the current list of ideas for VideoLAN project, for [https://summerofcode.withgoogle.com Google Summer Of Code 2017].

The list is not exhaustive, and is not limitative. Feel free to apply with '''your own idea!'''

== Introduction & Information ==

This wiki page covers the attempt by the [[VideoLAN]] project to act as a mentoring organization for [http://code.google.com/soc/ Google Summer of Code], in order to improve [[VLMC]] and the [[libVLC]] engine.

[[VideoLAN]] was a mentoring organization in [[SoC 2007|2007]], [[SoC 2008|2008]], [[SoC 2009|2009]], [[SoC 2010|2010]], [[SoC 2011|2011]], [[SoC 2013|2013]] and [[SoC 2016|2016]].

This page list the ideas for VLMC, libVLC and VLC.

=== VideoLAN Movie Creator ===
[[VLMC]] is a cross-platform non-linear video editing software based on libVLC technology. It was started as a final year student project at the French IT school [http://www.epitech.eu EPITECH].

[[VLMC]] currently awaits a transition to the current libvlc API and it's actual 1.0 release!

=== libVLC ===

{{VLC}} is a cross-platform multimedia player, encoder and streamer application. It is one of the most successful open-source projects without any professional structure underneath.

{{VLC}} is downloaded at an approximate monthly rate of 23 millions from the main website and that's not including third-party distributions (Linux)!

You can find more information on [http://en.wikipedia.org/wiki/VLC_media_player VLC on Wikipedia] or on this [[Main Page|wiki]].

The engine of VLC is libVLC, and is used by VLMC.

=== Summer of Code ===

If selected and developed, SoC projects for VLMC and VLC will be included in later releases.

All projects are covered by the GPL (v2+) or LGPL (v2.1+) licenses depending on the module.

=== Compile libVLC or VLMC ===
This may sound trivial, but it's harder than many expect. See https://wiki.videolan.org/Category:Building/ for more informations.

=== Provide a small patch ===
To demonstrate your skills, share a small patch with us. This will let you become familiar with [[Git]], in case you don't know it already and our process on [[Sending Patches VLC|merging patches]].

=== Let's get in touch ===

If you have a doubt, are not sure about anything or want clarification, please get in touch with us.

We have 3 major communication channels: Our [https://mailman.videolan.org/mailman/listinfo mailing-lists] to discuss patches and further development related topics. Furthermore, we have our [http://forum.videolan.org web forums] for VLC-related end-user support - a VLMC section will be created once the product is published. Finally, there is our IRC channel ''#videolan'' (for libVLC) and ''#vlmc'' on the ''Freenode'' network. It's open to any kind of discussion. Usage issues, questions how to compile VLC/VLMC, getting to know the fellow developers, etc.

= Ideas for VLMC =

== Port to Android ==

'''Project Description''':
VLMC is now working on the desktop. It would be nice to port it also to the mobile world, starting by Android.

This project would require to adapt to smaller screens, and simplify the UI to fit the Android workflow.

'''Tasks to do''':
# Fix the VLMC build for Android. As libVLC works fine on Android, this is more focused on compiling the Qt part for Android.
# Split more parts of the UI in components that are reusable on mobile.
# Change the components to fit the small resolutions of the Android devices.
# Rewrite some UI components in QML.
# Write a simpler timeline widget for Mobile workflows.

'''Requirements''': This project requires '''C++/Qt/qml''' knowledge, and access to Android devices.

''Proposed mentors: Geoffrey/Hugo''

== Media Workflow rework ==

'''Project Description''':
VLMC is now working on the desktop, but the media workflow is quite slow and is missing some common use cases.

This should be fixed in [https://github.com/mltframework/mlt MLT] framework backend for libVLC and is the continuation from the work from the previous Summer of Code.

'''Tasks to do''':
# Understand the MLT libVLC backend codebase,
# Clean the backend and port it to a cleaner code state in C++,
# Benchmark the code and make it more efficient,
# Work to merge this backend upstream,
# Implement all the missing features in libVLC.

'''Requirements''': This project requires '''C/C++''' knowledge, and understanding of multimedia concepts is a good positive point.

''Proposed mentors: Hugo''

== Workflow audio filters ==

'''Project Description''':
VLMC is now working on the desktop, but we need to have a good setup of audio filters to make it usable for most people.

'''Tasks to do''':
# Understand the VLMC and MLT codebase interactions,
# Add audio filters on the MLT framework backend using the [https://en.wikipedia.org/wiki/LADSPA LADSPA]/[http://lv2plug.in/ LV2] library or a similar open source library,
# Code the interface corresponding to those filters, and their options,
# Prepare visualizations, and notably for soundwave filters,
# Integrate those inside the timeline UI,
# Optimize.

'''Requirements''': This project requires '''C++/Qt/qml''' knowledge, and enough understanding of audio.

''Proposed mentors: J-B''

== Workflow video filters ==

'''Project Description''':
VLMC is now working on the desktop, but we need to have a good setup of video filters to make it usable for most people.

'''Tasks to do''':
# Understand the VLMC and MLT codebase interactions,
# Add video filters on the MLT framework backend using the [https://git.sesse.net/?p=movit;a=summary movit] library or a similar open source library,
# Code the interface corresponding to those filters, and their options,
# Add transitions between clips
# Code the interface to manage those transitions,
# Optimize the code.

'''Requirements''': This project requires '''C/C++''' knowledge.

''Proposed mentors: Felix''

== Improve multiplatform support ==
VLMC is aiming at being fully cross platform, but drifted a bit from that goal. While most VLMC's code is cross platform, and can be easily built targeting platforms, some dependencies might prove more difficult to build or compose with VLMC.

'''Tasks to do''':
# Fix MLT cross compilation for Windows (This will most likely require patching directly inside MLT, all contributions must be sent upstream).
# Fix medialibrary code & build process on macOS (and potentially iOS). The medialibrary misses some platform specific code to be able to list all connected drives (hard drives & USB removable storage, mostly) along with filesystem browsing
# Update the documentation along the way
# Create jenkins build configuration to have nightly builds on jenkins.videolan.org & nightlies.videolan.org for all supported platforms

'''Requirements''': This project requires buildsystems/toolchains knowledge, basic system programming on macOS & Windows

''Proposed mentors: Hugo''

= Key ideas for libVLC =

== Fuzz libVLC with LibFuzzer ==

'''Project Description''':
libFuzzer ((http://llvm.org/docs/LibFuzzer.html).) is a library for coverage-guided fuzz testing.

'''Tasks to do''':
* The first step of this GSoC project is to implement Fuzz Targets (http://llvm.org/docs/LibFuzzer.html#fuzz-target) to test various parts of the libVLC project. The non exhaustive parts will be the following libVLC modules API: "decoder", "encoder, "access", "packetizer", "demuxer". For each parts, the student will have to understand the module API in order to effectively implement the target.

* The second step is to find valid corpus (http://llvm.org/docs/LibFuzzer.html#corpus) for every module types and for every modules (mkv input for mkv demuxer, mp4 input for mp4 demuxer, h264 input for h264 decoder...).

* The third step is to host and run the fuzzer. It's not decided yet if the fuzzer will be hosted by google (https://github.com/google/oss-fuzz) or by the VideoLan association.

* If there is enough time, the fourth and final step is to fix the issues that has emerged during the previous steps.

'''Requirements''':
This project requires '''C''' and '''C++''' knowledge.

''Proposed mentor: tguillem''

== libVLC AirPlay support ==

'''Project Description''':
libVLC is now able to send video to the ChromeCast devices. We want to be able to do the same using the Airplay protocol, for Apple devices.

We want to be able to cast from any device, including Android or Windows machines, on all support Airplay devices, like Apple TV, iOS devices and audio amplificators.

This will use the new renderer APIs added in libVLC 3.0. Those APIs will need to be extended to allow the renderer to kick in during the playback.

'''Tasks to do''':
The work will consist of the following tasks:
* documentation on the [https://nto.github.io/AirPlay.html AirPlay protocol],
* documentation on the '''RAOP''' VLC module,
* implementation of the detection/discovery of the supported devices,
* implementation of the protocol to discuss with the device,
* modify the device control in order to transcode on demand,
* polish and release.

'''Advice'''
Please have a look at the following files: {{file|modules/stream_out/chromecast/chromecast_ctrl.cpp|Chromecast}} {{file|include/vlc_renderer_discovery.h|renderer API}}
A motivated and fast enough student could pair this task with the UPnP renderer!

'''Requirements''':
This project requires '''C''' knowledge and access to some Airplay devices.

''Proposed mentor: steve''

=== Bonus: AirPlay target ===

See https://trac.videolan.org/vlc/ticket/5752

== libVLC UPnP renderer support ==

'''Project Description''':
libVLC is now able to send video to the ChromeCast devices. We want to be able to do the same using the UPnP Renderer protocol, for all the connected TV devices that support this protocol.

We want to be able to do that from any device, including Android, iOS or Windows machines.

This will use the new renderer APIs added in libVLC 3.0. Those APIs will need to be extended to allow the renderer to kick in during the playback.

'''Tasks to do''':
The work will consist of the following tasks:
* documentation on the [http://upnp.org/resources/documents/UPnP_AV_tutorial_July2014.pdf UPnP renderer] protocol and on the libupnp APIs,
* implementation of the detection/discovery of the supported devices,
* implementation of the protocol to discuss with the device,
* modify the control of the device in order to transcode on demand,
* polish and release.

'''Advice''':
Please have a look at the following files: {{file|modules/stream_out/chromecast/chromecast_ctrl.cpp|Chromecast}} {{file|include/vlc_renderer_discovery.h|renderer API}}
A motivated and fast enough student could pair this task with the Airplay renderer!

'''Requirements''':
This project requires '''C''' knowledge and access to some connected TV supporting this protocol.

''Proposed mentor: tguillem''

== VLC web interface modern look ==

'''Project Description''':
The [[Web Interface |Web interface]] of VLC is a very ugly player and we want to improve that quite a bit.

It is often used to control VLC as a remote, and rarely as a remote playback tool. We want to change that.

This can be done in React, RxJS or Vue.JS to achieve a modern look, with transparency and cross-platform support.

'''Tasks to do''':
* Find the correct JS framework and buildsystem to integrate into VLC
* Discuss designs and show proof of concept
* Code the player part of the page,
* Code the playlist and video effects controllers
* Code the transcoding and streaming parts.

'''Requirements''':
This project requires '''JavaScript''' knowledge and experience. The choice of the Framework can be discussed before starting the project, if needed.

''Proposed mentor: David Loiret''

== libVLC 3D video support ==
'''Project Description''':
libVLC is able to play most 2D and Side-By-Side videos, but the support of 3D is very limited.

Because of '''360''' and '''VR''' support, the attention about 3D is getting very popular those days. We need to support that in libVLC.

'''Tasks to do''':
* understand of the usual 3D formats used by different medias
* code the core control of the different viewer points (left-only, right-only, SxS, nVidia 3D, etc...),
* implement those changes inside the OpenGL and Direct3D outputs,
* code the interface to change those viewer points,
* code the video filter corresponding to the OpenGL transformations,

'''Requirements''':
This project requires '''C''' knowledge. OpenGL knowledge and access to a 3D TV are a plus.

''Proposed mentor: adrien''

== libVLC VR support ==
'''Project Description''':
libVLC is able to play most 2D and 360 videos, but the support of VR is very limited.

Because of 360 and VR support, the attention about '''VR''' is getting very popular those days. We need to support that in libVLC, with an Oculus, a Vive, or a similar headset.

'''Tasks to do''':
* understand the different types of 360, 360-stereo, VR movie types and the different headsets types,
* integrate a new headset view in a libvlccore module,
* integrate a new headset control in a libvlccore module, to get rotation,
* integrate the control UI with the headset,
* optionaly code a VR theater mode inside the OpenGL or D3D module.

'''Requirements''':
This project requires '''C''' knowledge and access to a VR headset.

''Proposed mentor: adrien''

== VLC Qt interface redesign ==
'''Project Description''':
The VLC interface is quite outdated on Linux and Windows. It has a lot of features, but some are not properly exposed.

This project for the summer is to rework heavily this interface to make it beautiful and useful again.

'''Scope of the tasks to do''':

The idea is to get closer to what the WinRT/UWP interface looks like ''(search on google image to get an idea)'', but other ideas are welcome.

The WinRT interface is simpler, more user friendly, and has a better "media center" feel into it.

It would require integration with the media library and with the current interface.

Qml is the preferred way of improving the current UI.

'''Requirements''':
This project requires '''Qt/C++''' knowledge.

''Proposed mentor: J-B''

== VLC macOS interface redesign ==
'''Project Description''':
The VLC interface is quite outdated on macOS.

This project for the summer is to rework heavily this interface to make it beautiful and useful again.

'''Scope of the tasks to do''':

The idea is to get closer to what the Apple TV/iOS interface looks like ''(search on google image to get an idea)'', but other ideas are welcome.

The iOS/AppleTV interface is simpler, more user friendly, and has a better "media center" feel into it.

It would require integration with the media library and with the current interface.

Starting from the current UI is a requirement.

'''Requirements''':
This project requires '''Obj-C''' knowledge.

''Proposed mentor: David F''

== VLC cryptographic updates ==
'''Project Description''':
VLC is already using '''GPG signatures''' to achieve secure updates on the Windows platform.

But the updates are currently signed
with a single master key which is pinned into the source code and VLCs in the wild aren't able to check for revocations of this key.

'''Tasks to do''':

Therefore we would like to improve this situation by:

* being able to sign developers' keys that can sign VLC binaries on behalf of this master key
* support revocations of these developer's key
* provide a master key upgrade path

'''Requirements''':
This project requires solid notions of '''C and Crypto'''.

''Proposed mentor: geal''

== VLC crashes server ==
'''Project Description''':
VLC is now moving to [https://chromium.googlesource.com/breakpad/breakpad breakpad] to report the crashes.

But we need a fast server to process the reports, preferably written in Go.

'''Tasks to do''':
* understand breakpad and minidumps
* finish the breakpad integration for Windows
* write a breakpad server similar to the one from libreoffice, in Go,
* write a frontend for statistics and common reports,
* test it for macOS and Windows crashes.

'''Requirements''':
This project requires knowledge of '''Go and Debugging'''.

Chouquette: Clarify mingw-w64 version requirement

This page will help you to compile {{VLC}} for [[Windows]].

== Building Methods ==

If you want to build VLC from source, you have several choices:

{| class="wikitable"
|-
! Method
! Documentation
! Notes
|-
| '''MinGW on Linux'''
| [[Win32Compile#Obtaining_the_toolchain|Obtaining the toolchain]]
| '''Preferred''' method involving cross-compilation from Linux. On computers running Microsoft Windows, a virtual machine is necessary to run Linux.
|-
| '''[http://www.mingw.org MSYS+MinGW]''' on Windows
| [[Win32CompileMSYS|Compile with MSys]]
| '''Native''' compilation method. MSYS is a minimal build environment to compile Unix-style projects directly on Microsoft Windows. This is '''not officially supported''' by VideoLAN. Best of luck.
|-
| '''Cygwin''' on Windows
| [[Win32CompileCygwinNew|Compile with Cygwin]]
| Cygwin method. Cygwin emulates a POSIX environment to compile on Microsoft Windows. This is '''error'''-prone and '''slow''' and therefore not recommended.
|}

== Obtaining the cross-compilation toolchain ==
All this howto is focused on '''Debian/Ubuntu'''. For other distribution, please find the related package names, but they should be very similar.

'''Ubuntu 14.04''' is too old to compile VLC.

=== Host triplet ===
A number of commands below include the toolchain identifier, called the ''host triplet''.

This value is '''essential''': it instructs the build system to use the correct toolchain and compile the program for Windows.
Without the value, the build system will perform a native compilation for Linux (or whatever your computer runs). With an incorrect value, the build will fail.

The exact value depends on your installation of the toolchain.

Notably on Debian/Ubuntu, these values must be used:
* ''i686-w64-mingw32'' for Windows 32-bits, using the Mingw-w64 toolchain
* ''x86_64-w64-mingw32'' for Windows 64-bits, using the Mingw-w64 toolchain

Please make sure that you replace the keywords ''HOST-TRIPLET'' with either ''i686-w64-mingw32'' or ''x86_64-w64-mingw32'' adapted to your target Windows version (32-bit or 64-bit, respectively)

=== Compiler and binary toolchain ===

==== Mingw-w64 ====
To compile VLC for Windows (32-bits or 64-bits), the Mingw-w64 toolchain is required:

For the 32-bit version, run this:
# apt-get install gcc-mingw-w64-i686 g++-mingw-w64-i686 mingw-w64-tools

For the 64-bit version, this becomes:
# apt-get install gcc-mingw-w64-x86-64 g++-mingw-w64-x86-64 mingw-w64-tools

'''NB:''' you need mingw-w64 version 5.0.1 to compile it.

=== Development tools ===
You will also need:
* lua (5.2)
* all autotools: libtool, automake, autoconf, autopoint, make, gettext, pkg-config
* qt4-dev-tools, qt5-default (or qt4-default if qt plugin build fails)
* git, subversion cmake, cvs if you want to rebuild contribs
* wine-dev for creating Win32 packages
* zip [for creating .zip package], p7zip [for .7z package], nsis [for .exe auto-installer], bzip2 [for 'make prebuild]

'''Run:'''
# apt-get install lua5.2 libtool automake autoconf autopoint make gettext pkg-config
# apt-get install qt4-dev-tools qt5-default git subversion cmake cvs
# apt-get install wine64-development-tools zip p7zip nsis bzip2
# apt-get install yasm ragel ant default-jdk protobuf-compiler dos2unix

== Get the source code ==
$ git clone http://git.videolan.org/git/vlc.git vlc

See [[Git]] for more information.

== Go into the VLC directory ==
$ cd vlc

== Prepare [[Contrib Status|3rd party libraries]] ==

VLC depends on a sizable number of third party libraries. Before compiling VLC, you need to obtain compiled versions of those. There are two ways to achieve that:
* The ''prebuilt'' approach is much faster and easier, but only works with a narrow set of VLC versions.
* The ''manual build'' approach takes a lot of time and disk space, and somewhat error-prone.

Please note that the prebuilt library versions are intended for the latest current ''stable release'' of VLC. It is not compatible with old VLC versions, nor with newer or future versions.

At the time of writing (late 2016), the prebuilt libraries work with VLC 2.2.x '''only'''. To compile the VLC 3.0.x development branch, '''DO NOT USE''' the prebuilt libraries.

=== Prebuilt (fast) ===
$ mkdir -p contrib/win32
$ cd contrib/win32
$ ../bootstrap --host=HOST-TRIPLET
$ make prebuilt

=== Manually built (slow) ===
Or, if you want to compile the contribs yourself and are feeling adventurous and have lots of time to burn:
# apt-get install subversion yasm cvs cmake ragel autopoint

$ mkdir -p contrib/win32
$ cd contrib/win32
$ ../bootstrap --host=HOST-TRIPLET
$ make fetch
$ make

=== Linux 64-bit ===

If you are on Linux '''64-bit''', you '''SHOULD''' remove some files, or install the lib32 packages (ia32-libs, multilibs, etc...)

$ rm -f ../i686-w64-mingw32/bin/moc ../i686-w64-mingw32/bin/uic ../i686-w64-mingw32/bin/rcc

=== Fix your contrib path ===

If your host triplet is not '''i686-w64-mingw32''' (you are ''not'' compiling for Debian or Ubuntu), create a symlink to contribs:
$ ln -sf ''''HOST-TRIPLET'''' ../i686-w64-mingw32
Notice that there is no <code>../</code> before the host triplet. This is intentional, and if done properly, you should see a functioning symbolic link created in the parent directory (try <code>ls -l ..</code> and you should see <code>i686-w64-mingw32 -> x86_64-w64-mingw32/</code>).

=== Go Back ===

Go back to the VLC source directory:

$ cd -

== Configuring the build ==

=== Bootstrap ===
First, prepare the tree:
$ ./bootstrap

=== Configure ===
Then you can to configure the build with the <code>./configure</code> script.

Create a subfolder:
$ mkdir win32 && cd win32

Set your PKG_CONFIG_LIBDIR
$ export PKG_CONFIG_LIBDIR=$HOME/vlc/contrib/HOST-TRIPLET/lib/pkgconfig
$ export PKG_CONFIG_PATH_CUSTOM=$PKG_CONFIG_LIBDIR (for Archlinux only)

Execute the build configuration script:
$ ../extras/package/win32/configure.sh --host=HOST-TRIPLET --build=x86_64-pc-linux-gnu

'''N.B.''':
Use the host and build tuples respectively corresponding to '''your''' cross-compilation toolchain and build system respectively. The example above assumes you are compiling for ''Windows'' OS and ''Intel 686'' architecture, and the build system is ''GNU/Linux'' OS and ''x86 64-bits'' architecture. See [[#Host_triplet|above]] for list of common values.

Also, if you have a problem here (such as an error about Library dvdread), see the [[Talk:Win32Compile|Talk]] page.

Alternatively, you can run configure manually:
$ ../configure --host=HOST-TRIPLET --build=x86_64-pc-linux-gnu
See <code>'../configure --help'</code> for more information.

== Building VLC ==

Once configured, to build VLC, just run:
$ make

== Packaging VLC ==
Once the compilation is done, you can build self-contained VLC packages with the following <code>make</code> rules:

{| class="wikitable"
|-
! Command
! Description
|-
| <code>make package-win-common</code>
| Creates a subdirectory named <code>vlc-x.x.x</code> with all the binaries. You can run VLC directly from this directory.
|-
| <code>make package-win-strip</code>
| Same as above but will create 'stripped' binaries (that is, smallest size, unusable with a debugger).
|-
| <code>make package-win32-7zip</code>
| Same as above but will package the directory in a 7z file.
|-
| <code>make package-win32-zip</code>
| Same as above but will package the directory in a zip file.
|-
| <code>make package-win32</code>
| Same as above but will also create an auto-installer package. You must have NSIS installed in its default location for this to work.
|}

'''''Well done—you're ready to use VLC!'''''

== Extra information ==

=== Static compilation of plugins ===
You might want to use the following script to enforce static compilation.
Run as root, and use at your own risk.

#!/bin/sh

# This script enforces statically linking of libgcc, libstdc++-6, and libpthread,
# without needing to rebuild gcc and mingw-w64 from scratch.
# -static-libgcc -static-libstdc++ flags can not be used in a libtool build system,
# as libtool removes flags that it doesn't understand.

move() {
[ -f $1 ] || return 1
mkdir -p old/
mv -v $* old/
return 0
}

for x in i686 x86_64
do
library_path_list=`$x-w64-mingw32-gcc -v /dev/null 2>&1 | grep ^LIBRARY_PATH|cut -d= -f2|sort|uniq`
IFS=':'
for i in $library_path_list
do
cd $i
move libstdc++-6.dll libstdc++.dll.a libgcc_s.a libgcc_s_sjlj-1.dll && ln -s libgcc_eh.a libgcc_s.a
move libpthread.dll.a libwinpthread.dll.a
move libwinpthread-1.dll
[ -d ../bin ] && cd ../bin && move libwinpthread-1.dll
done
done

exit 0

=== Mingw32 ===
Up to versions 2.0.x, VLC was compiled with the older mingw32 toolchain, which only supports 32-bits Windows. If you have problems with mingw-w64, you can try mingw32 instead:

* '''Debian/Ubuntu''': run <code>apt-get install gcc-mingw32 mingw32-binutils</code>. Note that at least version 3.17 of Mingw32 is required, which Debian does not provide. You may obtain mingw32-runtime-3.17 [http://people.videolan.org/~jb/debian/mingw32-runtime_3.17.0-0videolan_all.deb here].
* '''Gentoo''' users can <code>emerge crossdev && crossdev mingw32</code>
* '''ArchLinux''' users can <code>pacman -S mingw32-gcc</code>
* '''Fedora''' users should read [[Win32Compile Under Fedora]]
* Other '''Linux''' systems may attempt http://www.mingw.org/wiki/LinuxCrossMinGW

Building VLMC

2016-03-11T11:03:21Z

Chouquette: /* Building VLMC from source */

== Building VLMC from source ==

This wiki page has information on building [[VideoLAN Movie Creator]], VLMC from source.
VLMC (VideoLAN Movie Creator) is a free video editing software,
offering features to realize semi-professional quality movies,
but with the aim to stays simple and user-friendly.

=== Resources ===

VLMC requires a c++ compiler (g++), cmake, Qt(4.6+), libVLC and frei0r plugins.

To install Qt, refer: http://qt-project.org/downloads

To install libVLC, you are required to compile VLC

To get the current source of VLC player, refer: http://wiki.videolan.org/GetTheSource

For information on using Git, refer: http://wiki.videolan.org/Git

For Information on generic compilation of VLC, refer: http://wiki.videolan.org/Compile_VLC

In case you are interested in mailing list, goto:
http://mailman.videolan.org/listinfo/

We have two VLMC mailing lists:
* vlmc-announce: Official announcements (release, events, ...)
* vlmc-devel: Developers discussions

=== Getting the code ===

You can fetch the current VLMC working tree using Git:
git clone https://code.videolan.org/videolan/vlmc.git

Do the same for VLC (as described in http://wiki.videolan.org/GetTheSource):
git clone git://git.videolan.org/vlc.git

=== Building VLMC on Linux ===

Following is the cleanest way of compiling VLMC (commands for *nix OS)

1. Compile and install libVLC, libVLC is required by VLMC (You can also install VLC using your linux distribution), for example:
cd path_to_vlc_src
./bootstrap
./configure ''--your-options-here (see --help)''
make
sudo make install

2. For Compiling VLMC:
cd path_to_vlmc_src
mkdir build && cd build
cmake ..
make

3. Run VLMC:
./vlmc

==== Building VLMC in developer mode ====

By default, VLMC enables a crash handler, which is responsible for saving a backup of the project in the event of a crash.

While this might be handy for the users, it makes life harder on developers, since a debugger would attach to the daemon process instead of VLMC.

In order to disable this, you'll need a tool such as ccmake, or cmake-gui, to disable the WITH_CRASHHANDLER option.

Alternatively, you can invoke cmake with -DWITH_CRASHHANDLER=OFF flag

=== Cross Compiling VLMC for Windows on Linux ===

VLMC can be cross-compiled for Windows, on Linux using mingw:

cd contribs
sh contribs.sh
cd ..
mkdir win32 && cd win32
cmake -DCMAKE_TOOLCHAIN_FILE=../cmake/toolchain-win32.cmake ..
make

=== Compiling on Mac OS ===

==== Dependencies ====
* Build tools: Xcode command-line tools
* homebrew

==== Get the sources: ====
git clone https://code.videolan.org/videolan/vlmc.git

==== Get the actual dependencies: ====
* brew tap tomahawk-player/tomahawkqt5
* brew install make
* brew install vlc
* brew install qt5
* brew install frei0r

==== Compile vlmc: ====
Now cd to root source directory and build:
mkdir build && cd build
cmake ..
make

This will by default create a Mac Bundle, vlmc.app in /build/bin

==== To create a dmg image: ====
Uncomment #dmg in /src/CMakeLists.txt, at the end of the file.
and follow the build process, the dmg will be created in /build/bin

To create a dmg image, uncomment #dmg in /src/CMakeLists.txt, at the end of the file.
This creates the app/dmg in <build-directory>/bin

=== Packaging VLMC ===

* On Linux, you can create deb/rpm package by using:
make package

* You can create NSIS installer for Windows using cross-compiling on Linux:
make installer

Start hacking ;-)

Outreachy May 2016

2016-02-19T18:05:50Z

Chouquette: /* Key ideas for VLMC */

This wiki page covers the work of the [[VideoLAN]] project as a mentoring organization for [https://wiki.gnome.org/Outreachy Outreachy the successor of the Outreach Program for Women], in order to improve {{VLC}} and [[VLMC]].

To find generic information about the Outreachy program, please see the '''[https://wiki.gnome.org/Outreachy official website]'''.

=== VLC media player ===

{{VLC}} is a cross-platform multimedia player, encoder and streamer application. It is one of the most successful [http://www.videolan.org/videolan/ open-source projects without any professional structure] underneath.

{{VLC}} is downloaded at an approximate monthly rate of 40 millions from the main website and that's not including third-party distributions (like Linux, BSD, Android or iOS)!

You can find more information on [http://en.wikipedia.org/wiki/VLC_media_player VLC on Wikipedia] or on this [[Main Page|wiki]].

=== VideoLAN Movie Creator ===
[[VLMC]] is a cross-platform non-linear video editing software based on VLC technology. It was started as a final year student project at the French IT school [http://www.epitech.eu EPITECH].

[[VLMC]] currently awaits a transition to the current libvlc API and it's actual 1.0 release!

=== Outreachy May 2016 ===

If selected and developed, Outreachy projects for VLC or VLMC will be included in later releases.

All projects are covered by the GPL (v2+) or LGPL (v2.1+) licenses depending on the module.

=== VLC and VLMC Idea categories ===

''''' You should really read this'''''

This page is split in three lists of ideas:

#The ''main ideas'' are what seem to be ''key projects'' for VLC or VLMC and should be more ''thrilling'' than the other ones; we have assigned a potential mentor to each of these.
#The other ideas are less detailed but could be good ideas too.
#[[Mini Projects]] are short-span projects which can be given as Qualification tasks or extended to be a full project.

'''Original good ideas will be valued'''. We don't want to impose anything. This is Free and Open Source software.

If you don't want to apply for Outreachy but want other ideas to develop on, check the [[Mini Projects]] page!

And on the IRC channel ''#videolan'' on the ''Freenode Network'', you can have even more ideas.

== Getting started ==

=== Compile VLC or VLMC ===
This may sound trivial, but it's harder than many expect. VLC's and VLMC's compilation chains are different for every operating system. They don't really use the default toolchains on Windows or OS X, but a simple *nix like ./configure && make doesn't really do the trick either. We have plenty of information available on this wiki and we will happily provide help on our IRC channel.

=== Provide a small patch ===
To demonstrate your skills, share a small patch with us. This will let you become familiar with [[Git]], in case you don't know it already and our process on [[Sending Patches VLC|merging patches]].

=== Let's get in touch ===
We have 3 major communication channels at VideoLAN. Our [https://mailman.videolan.org/mailman/listinfo mailing-lists] to discuss patches and further development related topics. Furthermore, we have our [http://forum.videolan.org web forums] for end-user support. This means 2 things: 1) people using VLC media player on any operating system 2) people using libvlc or the VLC web plugin in their own applications or installations. Finally, there is our IRC channel ''#videolan'' on the ''Freenode'' network. It's open to any kind of discussion. Usage issues, questions how to compile VLC or VLMC, getting to know the fellow developers, etc.

=== How to apply? ===
The application process for the May 2016 rout will open on February 16, 2015 and '''application deadline''' is '''March 22''' (no exceptions!). Please submit your application on the [https://outreachy.gnome.org official program website]. Previously, please check the [https://wiki.gnome.org/Outreachy#Eligibility eligibility requirements] :-)

== Key ideas for VLMC ==

=== Implement a real Audio/Video sync ===

So far, the lip-syncing strategy used by VLMC is pretty much "hope it works".

As you would think, this quite often leads to desync, and thus makes VLMC unusable.

We need to come up with a real synchronization strategy, quite likely based on an abstract clock & PTS

''Proposed mentor: chouquette''

=== Plug-in new libvlcpp & medialibrary ===

VLMC uses a from-sratch C++ binding to libvlc, which is stuck a few years in the past.
Meanwhile, a new binding got written (https://code.videolan.org/videolan/libvlcpp/tree/master), and needs to be plugged in.

We also started working on a cross-platform media library, to replace the low-featured one, present in VLMC.

This media library will handle discovering media for the used, instead of having to manually importing every single file. This should also allow us to kill some of the "Backend" code, as a fair share of it is designed to create thumbnails. This is now done by the medialibrary, and can go away from the VLMC source code.

This probably requires a good C++ knowledge, as both libvlcpp & medialibrary make a heavy use of C++11 & templates meta-programming.

''Proposed mentor: chouquette''

=== Import/Save to/from cloud services ===

It would be a great addition to VLMC to be able to import some medias from a cloud service, and being able to export the result to another.

Since there are so many different cloud providers, we would like to have a "libcloudstorage" that would handle all the boilerplate out of VLMC's source code.

This lib can then easily be used to allow the user to use multiple service.

The cherry on the top would be to integrate this lib cloud storage into the medialibrary project, in order to automatically discover & analyze media stored on the cloud.

''Proposed mentor: jb, chouquette''

=== Remote UI ===

We would like to have a way to use VLMC from a web browser. You can easily imagine having a nice, shiny & simple UI for minimal movie edition, which would go hand in hand with the cloud storage feature.

This task aims toward the uncoupling of the rendering backend & UI, as the renderer will run server side, while the UI runs on the client side.

The idea is to be able to have a UI interacting with the renderer without having to be in the same process, or even machine.

''Proposed mentor: jb, chouquette, fkuehne''

=== Unit tests ===

VLMC is *not* tested.

Well, it is, but manually, which is not good enough. There are many race conditions, crash, deadlocks yet to be discovered.

The UI also has some fairly funky behavior when being stressed out, and that needs to be tested as well.

This task is about writing a unit test suite for both the renderers & the UI. Most likely, this will mean adding some mocking machinery, and therefor hiding all our classes behind an API.

This task is definitely a requirement before we are able to clean & modernize the code base!

''Proposed mentor: chouquette''

== Key ideas for VLC ==

=== Assembly optimizations in VLC ===

If you are fond of writing ASM and you are fluent in MMX/SSE2/SSE4, there are many interesting things in VLC to speed up.

* Profiling VLC
* video filters ASM speedups (see modules/video_filter/blend.c)
* audio filters ASM speedups (see modules/audio_filter/equalizer.c)
* Porting other ASM video filters to VLC.

This project needs some good ASM knowledge and good C experience.

*Stuff to read: http://www.agner.org/optimize/

''Proposed mentor: [[User:J-b|jb]], flx42''

=== Advanced Audio Filters ===

We are looking for a skilled '''audiophile''' that knows a lot about audio theory and practice to work on new audio filters.

Notably:
* SRS WoW like or other 3D effects;
* channels mixing, notably upmixing, like Prologic-II;
* tracks mixing, and transitions;
* scriptable new audio filters in lua and enable users to create whatever audio filtering function they want in a Lua script;
* LADSPA or other libraries integration.

This project needs some good audio knowledge and good C experience.

''Qualification task'': port any audio filter from MPlayer

''Proposed mentor: [[User:Geal|geal]]''

=== VLC Test Suite ===

This project aims at making automatic tests to improve VLC quality.

*Write a series of tests for vlc-internal
*Integrate a framework for automated plugins testing with the automake build system
*Automate the different codec playback/mux/etc tests
*Automate the subtitles tests
*Write tests for the different bindings: Mac OS X Framework/Python Bindings... etc.

This project is a code project, require good knowledge of C

''Proposed mentor: Rémi''

=== VLC Personal Cloud Project 2.0 ===

The personal cloud project is a simple project to allow people to play their media files anywhere in the world.

Through the http interface of VLC, a user can:

*list the medias from the Media Library,
*play those medias,
*those medias get transcoded and streamed in:
**Flash
**Silverlight
**iPhone format
**Android format
**html5
**A VLC webplugin

A good example of the aim is http://www.vodobox.c.la/

This project has to work on the configuration and NAT traversal.

This projects needs knowledge in HTML and JS; it might require C coding.

''Proposed mentor: [[User:J-b|jb]]''

=== Playlist improvements ===

We need to reinforce the media library capabilities and its integration with external metadata sources, notably for TV shows.

''Proposed mentor: ??''

=== AirPlay streaming ===

We need to be able to stream everything to your Google TV, Apple TV or raspberrypi powered shairport service. Airport is an non-open protocol that allows wireless streaming of audio, video, multimedia to supported devices.

The tasks would consist of:
* Understanding how AirPlay works, try with any device if available.
* Configure a test setup using raspberrypi or your own computer or any TV device if available, play with couple of available players who support AirPlay. This is just to get a feel of what it is you will be trying to implement for vlc-android.
* Study couple of opensource implementations like shairport
* Run/test/deploy VLC on simulator or android device
* Implement an AirPlay aout that would stream audio to your AirPlay supported device (shairport with rpi/computer or Apple TV or Google TV)
* Test with couple of android devices if available, ask mentors and community to test, report bugs, suggestions
* Study how video works, vout for vlc works, if have time implement video streaming as well.

''Proposed mentor: ??''

=== VLC Sync Play across devices ===
By leveraging zeroconf and rtsp make possible to decode in sync in multiple devices a video stored in one.
Tasks:
* Implement a simple protocol for discovery and announce
* Implement the discovery system
* At least one of the following
** Provide a UI for Qt (Windows / Linux)
** Provide a UI for Android
** Provide a UI for OS X
''Proposed mentor: lu_zero''

=== Port VLC's NPAPI web plugin to PPAPI ===
We need to support the PPAPI interfaces this summer to keep playback support within Google Chrome, since they dropped the existing NPAPI architecture. A proof-of-concept was developed already, but needs refactoring, polishing and testing.

Requires good C or/and C++ knowledge and a basic understanding of web browser internals. The ability to test on more than one platform would be a very strong plus.

''Proposed Mentor: [[User:Fkuehne|feepk]]''

=== Add Owncloud, MEGA and Yandex.Disk cloud support to VLC for iOS ===
Following the success of our native integration with Google Drive, Dropbox, OneDrive and Box, we want to integrate with Owncloud, MEGA and Yandex.disk, which are the last remaining major cloud services left to add! :)

Requires good Objective-C and optionally swift knowledge as well as a basic understanding of cloud services and network programming. Additionally, requires a Mac running OS X 10.10 or later.

''Proposed Mentor: [[User:Fkuehne|feepk]]''

=== Add proper audio playback UI to VLC for iOS ===
VLC for iOS is a recognized and well known video player. Few people know that it is actually capable of playing music and podcasts, too and there is a reason for that. The UI is not really suitable for it. Make it so!

Requires good Objective-C and optionally swift knowledge as well as basic design skills. Additionally, requires a Mac running OS X 10.10 or later.

''Proposed Mentor: [[User:Fkuehne|feepk]]''

== Other Ideas for VLC ==

=== DVD audio support ===
Very difficult project for Audio fans
''Proposed mentor: [[User:J-b|jb]]''

=== Device synchronisation===
Sync your mp3 player with the media library
''Proposed mentor: ???''

=== HD DVD support ===
Very difficult project for someone having the right hardware
''Proposed mentor: [[User:J-b|jb]]''

=== Multi-Angle DVD support ===
We need multi-angle DVD support

=== Provide a small patch ===
To demonstrate your skills, share a small patch with us. This will let you become familiar with [[Git]], in case you don't know it already and our process on [[Sending Patches VLC|merging patches]].

=== Let's get in touch ===
We have 3 major communication channels: Our [https://mailman.videolan.org/mailman/listinfo mailing-lists] to discuss patches and further development related topics. Furthermore, we have our [http://forum.videolan.org web forums] for end-user support. Finally, there is our IRC channel ''#vlmc'' on the ''Freenode'' network. It's open to any kind of discussion. Usage issues, questions how to compile VLMC, getting to know the fellow developers, etc.

== Key ideas for VLMC ==

=== Implement a real Audio/Video sync ===

So far, the lip-syncing strategy used by VLMC is pretty much "hope it works".

As you would think, this quite often leads to desync, and thus makes VLMC unusable.

We need to come up with a real synchronization strategy, quite likely based on an abstract clock & PTS

''Proposed mentor: chouquette''

=== Plug-in new libvlcpp & medialibrary ===

VLMC uses a from-sratch C++ binding to libvlc, which is stuck a few years in the past.
Meanwhile, a new binding got written (https://code.videolan.org/videolan/libvlcpp/tree/master), and needs to be plugged in.

We also started working on a cross-platform media library, to replace the low-featured one, present in VLMC.

This media library will handle discovering media for the used, instead of having to manually importing every single file. This should also allow us to kill some of the "Backend" code, as a fair share of it is designed to create thumbnails. This is now done by the medialibrary, and can go away from the VLMC source code.

This probably requires a good C++ knowledge, as both libvlcpp & medialibrary make a heavy use of C++11 & templates meta-programming.

''Proposed mentor: chouquette''

=== Import/Save to/from cloud services ===

It would be a great addition to VLMC to be able to import some medias from a cloud service, and being able to export the result to another.

Since there are so many different cloud providers, we would like to have a "libcloudstorage" that would handle all the boilerplate out of VLMC's source code.

This lib can then easily be used to allow the user to use multiple service.

The cherry on the top would be to integrate this lib cloud storage into the medialibrary project, in order to automatically discover & analyze media stored on the cloud.

=== Remote UI ===

We would like to have a way to use VLMC from a web browser. You can easily imagine having a nice, shiny & simple UI for minimal movie edition, which would go hand in hand with the cloud storage feature.

This task aims toward the uncoupling of the rendering backend & UI, as the renderer will run server side, while the UI runs on the client side.

The idea is to be able to have a UI interacting with the renderer without having to be in the same process, or even machine.

=== Unit tests ===

VLMC is *not* tested.

Well, it is, but manually, which is not good enough. There are many race conditions, crash, deadlocks yet to be discovered.

The UI also has some fairly funky behavior when being stressed out, and that needs to be tested as well.

This task is about writing a unit test suite for both the renderers & the UI. Most likely, this will mean adding some mocking machinery, and therefor hiding all our classes behind an API.

This task is definitely a requirement before we are able to clean & modernize the code base!

Chouquette: vlmc: Add remote UI

This wiki page covers the work of the [[VLMC]] project as a mentoring organization for [https://summerofcode.withgoogle.com Google Summer of Code], in order to improve our VideoLAN Movie Creator ([[VLMC]]).

=== VideoLAN Movie Creator ===
[[VLMC]] is a cross-platform non-linear video editing software based on VLC technology. It was started as a final year student project at the French IT school [http://www.epitech.eu EPITECH].

[[VLMC]] currently awaits a transition to the current libvlc API and it's actual 1.0 release!

=== Google Summer of Code Summer 2016 ===

If selected and developed, GSoC projects for VLMC will be included in the initial release!

All projects are covered by the GPL (v2+) or LGPL (v2.1+) licenses depending on the module.

== Getting started ==

'''Original good ideas will be valued'''. We don't want to impose anything. This is Free and Open Source software.

=== Compile VLMC ===
This may sound trivial, but it's harder than many expect. VLMC's compilation chain is different for every operating system. It doesn't really use the default toolchains on Windows or OS X, but a simple *nix like ./configure && make doesn't really do the trick either. We have plenty of information available on this wiki and we will happily provide help on our IRC channel.

Chouquette: /* Key ideas for VLMC */

This wiki page covers the work of the [[VideoLAN]] project as a mentoring organization for [http://gnome.org/opw/ Outreachy the successor of the Outreach Program for Women], in order to improve {{VLC}} and [[VLMC]].

=== VLC media player ===

{{VLC}} is a cross-platform multimedia player, encoder and streamer application. It is one of the most successful [http://www.videolan.org/videolan/ open-source projects without any professional structure] underneath.

{{VLC}} is downloaded at an approximate monthly rate of 40 millions from the main website and that's not including third-party distributions (like Linux, BSD, Android or iOS)!

You can find more information on [http://en.wikipedia.org/wiki/VLC_media_player VLC on Wikipedia] or on this [[Main Page|wiki]].

All projects are covered by the GPL (v2+) or LGPL (v2.1+) licenses depending on the module.

=== VLC and VLMC Idea categories ===

''''' You should really read this'''''

This page is split in three lists of ideas:

#The ''main ideas'' are what seem to be ''key projects'' for VLC or VLMC and should be more ''thrilling'' than the other ones; we have assigned a potential mentor to each of these.
#The other ideas are less detailed but could be good ideas too.
#[[Mini Projects]] are short-span projects which can be given as Qualification tasks or extended to be a full project.

'''Original good ideas will be valued'''. We don't want to impose anything. This is Free and Open Source software.

If you don't want to apply for Outreachy but want other ideas to develop on, check the [[Mini Projects]] page!

And on the IRC channel ''#videolan'' on the ''Freenode Network'', you can have even more ideas.

== Key ideas for VLC ==

=== Assembly optimizations in VLC ===

If you are fond of writing ASM and you are fluent in MMX/SSE2/SSE4, there are many interesting things in VLC to speed up.

* Profiling VLC
* video filters ASM speedups (see modules/video_filter/blend.c)
* audio filters ASM speedups (see modules/audio_filter/equalizer.c)
* Porting other ASM video filters to VLC.

This project needs some good ASM knowledge and good C experience.

*Stuff to read: http://www.agner.org/optimize/

''Proposed mentor: [[User:J-b|jb]], flx42''

=== Advanced Audio Filters ===

We are looking for a skilled '''audiophile''' that knows a lot about audio theory and practice to work on new audio filters.

Notably:
* SRS WoW like or other 3D effects;
* channels mixing, notably upmixing, like Prologic-II;
* tracks mixing, and transitions;
* scriptable new audio filters in lua and enable users to create whatever audio filtering function they want in a Lua script;
* LADSPA or other libraries integration.

This project needs some good audio knowledge and good C experience.

''Qualification task'': port any audio filter from MPlayer

''Proposed mentor: [[User:Geal|geal]]''

=== VLC Test Suite ===

This project aims at making automatic tests to improve VLC quality.

*Write a series of tests for vlc-internal
*Integrate a framework for automated plugins testing with the automake build system
*Automate the different codec playback/mux/etc tests
*Automate the subtitles tests
*Write tests for the different bindings: Mac OS X Framework/Python Bindings... etc.

This project is a code project, require good knowledge of C

''Proposed mentor: Rémi''

=== VLC Personal Cloud Project 2.0 ===

The personal cloud project is a simple project to allow people to play their media files anywhere in the world.

Through the http interface of VLC, a user can:

*list the medias from the Media Library,
*play those medias,
*those medias get transcoded and streamed in:
**Flash
**Silverlight
**iPhone format
**Android format
**html5
**A VLC webplugin

A good example of the aim is http://www.vodobox.c.la/

This project has to work on the configuration and NAT traversal.

This projects needs knowledge in HTML and JS; it might require C coding.

''Proposed mentor: [[User:J-b|jb]]''

=== Playlist improvements ===

We need to reinforce the media library capabilities and its integration with external metadata sources, notably for TV shows.

''Proposed mentor: ??''

=== AirPlay streaming ===

We need to be able to stream everything to your Google TV, Apple TV or raspberrypi powered shairport service. Airport is an non-open protocol that allows wireless streaming of audio, video, multimedia to supported devices.

The tasks would consist of:
* Understanding how AirPlay works, try with any device if available.
* Configure a test setup using raspberrypi or your own computer or any TV device if available, play with couple of available players who support AirPlay. This is just to get a feel of what it is you will be trying to implement for vlc-android.
* Study couple of opensource implementations like shairport
* Run/test/deploy VLC on simulator or android device
* Implement an AirPlay aout that would stream audio to your AirPlay supported device (shairport with rpi/computer or Apple TV or Google TV)
* Test with couple of android devices if available, ask mentors and community to test, report bugs, suggestions
* Study how video works, vout for vlc works, if have time implement video streaming as well.

''Proposed mentor: ??''

=== VLC Sync Play across devices ===
By leveraging zeroconf and rtsp make possible to decode in sync in multiple devices a video stored in one.
Tasks:
* Implement a simple protocol for discovery and announce
* Implement the discovery system
* At least one of the following
** Provide a UI for Qt (Windows / Linux)
** Provide a UI for Android
** Provide a UI for OS X
''Proposed mentor: lu_zero''

=== XML fast and small implementation ===

The goal of this project is to write a new XML backend, based on a smaller library than the full libxml2. Speed would be nice, but code size matters here. Beware: we need to have a stream-XML based API, not a DOM one.

This project requires good knowledge of C.

''Proposed mentor: [[User:etix|etix]]''

=== Port VLC's NPAPI web plugin to PPAPI ===
We need to support the PPAPI interfaces this summer to keep playback support within Google Chrome, since they dropped the existing NPAPI architecture. A proof-of-concept was developed already, but needs refactoring, polishing and testing.

Requires good C or/and C++ knowledge and a basic understanding of web browser internals. The ability to test on more than one platform would be a very strong plus.

''Proposed Mentor: [[User:Fkuehne|feepk]]''

=== Add Owncloud, MEGA and Yandex.Disk cloud support to VLC for iOS ===
Following the success of our native integration with Google Drive, Dropbox, OneDrive and Box, we want to integrate with Owncloud, MEGA and Yandex.disk, which are the last remaining major cloud services left to add! :)

Requires good Objective-C and optionally swift knowledge as well as a basic understanding of cloud services and network programming. Additionally, requires a Mac running OS X 10.10 or later.

''Proposed Mentor: [[User:Fkuehne|feepk]]''

=== Add proper audio playback UI to VLC for iOS ===
VLC for iOS is a recognized and well known video player. Few people know that it is actually capable of playing music and podcasts, too and there is a reason for that. The UI is not really suitable for it. Make it so!

Requires good Objective-C and optionally swift knowledge as well as basic design skills. Additionally, requires a Mac running OS X 10.10 or later.

''Proposed Mentor: [[User:Fkuehne|feepk]]''

== Other Ideas for VLC ==

=== DVD audio support ===
Very difficult project for Audio fans
''Proposed mentor: [[User:J-b|jb]]''

=== Device synchronisation===
Sync your mp3 player with the media library
''Proposed mentor: ???''

=== HD DVD support ===
Very difficult project for someone having the right hardware
''Proposed mentor: [[User:J-b|jb]]''

=== Multi-Angle DVD support ===
We need multi-angle DVD support

This page is split in three lists of ideas:

#The ''main ideas'' are what seem to be ''key projects'' for VLC or VLMC and should be more ''thrilling'' than the other ones; we have assigned a potential mentor to each of these.
#The other ideas are less detailed but could be good ideas too.
#[[Mini Projects]] are short-span projects which can be given as Qualification tasks or extended to be a full project.

'''Original good ideas will be valued'''. We don't want to impose anything. This is Free and Open Source software.

If you don't want to apply for Outreachy but want other ideas to develop on, check the [[Mini Projects]] page!

And on the IRC channel ''#videolan'' on the ''Freenode Network'', you can have even more ideas.

== Getting started ==

=== Compile VLC or VLMC ===
This may sound trivial, but it's harder than many expect. VLC's and VLMC's compilation chains are different for every operating system. They don't really use the default toolchains on Windows or OS X, but a simple *nix like ./configure && make doesn't really do the trick either. We have plenty of information available on this wiki and we will happily provide help on our IRC channel.

=== Provide a small patch ===
To demonstrate your skills, share a small patch with us. This will let you become familiar with [[Git]], in case you don't know it already and our process on [[Sending Patches VLC|merging patches]].

=== Let's get in touch ===
We have 3 major communication channels at VideoLAN. Our [https://mailman.videolan.org/mailman/listinfo mailing-lists] to discuss patches and further development related topics. Furthermore, we have our [http://forum.videolan.org web forums] for end-user support. This means 2 things: 1) people using VLC media player on any operating system 2) people using libvlc or the VLC web plugin in their own applications or installations. Finally, there is our IRC channel ''#videolan'' on the ''Freenode'' network. It's open to any kind of discussion. Usage issues, questions how to compile VLC or VLMC, getting to know the fellow developers, etc.

== Key ideas for VLMC ==

=== Implement a real Audio/Video sync ===

So far, the lip-syncing strategy used by VLMC is pretty much "hope it works".

As you would think, this quite often leads to desync, and thus makes VLMC unusable.

We need to come up with a real synchronization strategy, quite likely based on an abstract clock & PTS

== Key ideas for VLC ==

=== Assembly optimizations in VLC ===

If you are fond of writing ASM and you are fluent in MMX/SSE2/SSE4, there are many interesting things in VLC to speed up.

* Profiling VLC
* video filters ASM speedups (see modules/video_filter/blend.c)
* audio filters ASM speedups (see modules/audio_filter/equalizer.c)
* Porting other ASM video filters to VLC.

This project needs some good ASM knowledge and good C experience.

*Stuff to read: http://www.agner.org/optimize/

''Proposed mentor: [[User:J-b|jb]], flx42''

=== Advanced Audio Filters ===

We are looking for a skilled '''audiophile''' that knows a lot about audio theory and practice to work on new audio filters.

Notably:
* SRS WoW like or other 3D effects;
* channels mixing, notably upmixing, like Prologic-II;
* tracks mixing, and transitions;
* scriptable new audio filters in lua and enable users to create whatever audio filtering function they want in a Lua script;
* LADSPA or other libraries integration.

This project needs some good audio knowledge and good C experience.

''Qualification task'': port any audio filter from MPlayer

''Proposed mentor: [[User:Geal|geal]]''

=== VLC Test Suite ===

This project aims at making automatic tests to improve VLC quality.

*Write a series of tests for vlc-internal
*Integrate a framework for automated plugins testing with the automake build system
*Automate the different codec playback/mux/etc tests
*Automate the subtitles tests
*Write tests for the different bindings: Mac OS X Framework/Python Bindings... etc.

This project is a code project, require good knowledge of C

=== VLC Personal Cloud Project 2.0 ===

The personal cloud project is a simple project to allow people to play their media files anywhere in the world.

Through the http interface of VLC, a user can:

*list the medias from the Media Library,
*play those medias,
*those medias get transcoded and streamed in:
**Flash
**Silverlight
**iPhone format
**Android format
**html5
**A VLC webplugin

A good example of the aim is http://www.vodobox.c.la/

This project has to work on the configuration and NAT traversal.

This projects needs knowledge in HTML and JS; it might require C coding.

=== Playlist improvements ===

We need to reinforce the media library capabilities and its integration with external metadata sources, notably for TV shows.

''Proposed mentor: ??''

=== AirPlay streaming ===

We need to be able to stream everything to your Google TV, Apple TV or raspberrypi powered shairport service. Airport is an non-open protocol that allows wireless streaming of audio, video, multimedia to supported devices.

The tasks would consist of:
* Understanding how AirPlay works, try with any device if available.
* Configure a test setup using raspberrypi or your own computer or any TV device if available, play with couple of available players who support AirPlay. This is just to get a feel of what it is you will be trying to implement for vlc-android.
* Study couple of opensource implementations like shairport
* Run/test/deploy VLC on simulator or android device
* Implement an AirPlay aout that would stream audio to your AirPlay supported device (shairport with rpi/computer or Apple TV or Google TV)
* Test with couple of android devices if available, ask mentors and community to test, report bugs, suggestions
* Study how video works, vout for vlc works, if have time implement video streaming as well.

=== VLC Sync Play across devices ===
By leveraging zeroconf and rtsp make possible to decode in sync in multiple devices a video stored in one.
Tasks:
* Implement a simple protocol for discovery and announce
* Implement the discovery system
* At least one of the following
** Provide a UI for Qt (Windows / Linux)
** Provide a UI for Android
** Provide a UI for OS X
''Proposed mentor: lu_zero''

=== XML fast and small implementation ===

The goal of this project is to write a new XML backend, based on a smaller library than the full libxml2. Speed would be nice, but code size matters here. Beware: we need to have a stream-XML based API, not a DOM one.

This project requires good knowledge of C.

''Proposed mentor: [[User:etix|etix]]''

=== Port VLC's NPAPI web plugin to PPAPI ===
We need to support the PPAPI interfaces this summer to keep playback support within Google Chrome, since they dropped the existing NPAPI architecture. A proof-of-concept was developed already, but needs refactoring, polishing and testing.

Requires good C or/and C++ knowledge and a basic understanding of web browser internals. The ability to test on more than one platform would be a very strong plus.

=== Add Owncloud, MEGA and Yandex.Disk cloud support to VLC for iOS ===
Following the success of our native integration with Google Drive, Dropbox, OneDrive and Box, we want to integrate with Owncloud, MEGA and Yandex.disk, which are the last remaining major cloud services left to add! :)

Requires good Objective-C and optionally swift knowledge as well as a basic understanding of cloud services and network programming. Additionally, requires a Mac running OS X 10.10 or later.

''Proposed Mentor: [[User:Fkuehne|feepk]]''

=== Add proper audio playback UI to VLC for iOS ===
VLC for iOS is a recognized and well known video player. Few people know that it is actually capable of playing music and podcasts, too and there is a reason for that. The UI is not really suitable for it. Make it so!

Requires good Objective-C and optionally swift knowledge as well as basic design skills. Additionally, requires a Mac running OS X 10.10 or later.

Chouquette: /* Build and Deploy */

This page will help you compile '''VLC for WinRT'''

==Development Environment==

To develop VLC for WinRT, you would need to have:
* Windows 8.1
* Visual Studio 2013 with Update 2 (or Update 3)
* Windows 8.1 SDK (Recommended)
* Latest version of Git
* Lots of patience :D

==Get the source==

You can clone the VLC for WinRT git repository

git clone git://git.videolan.org/vlc-ports/winrt.git

==Get libVLC source==

====Packaged 7zip file====
You can download vlc.7z from [http://people.videolan.org/~hugo/vlc-Win32.7z here]. Extract the contents of vlc.7z and copy the contents to vlc folder of winrt source code

====Cross Compiling====
If you feel adventurous, you can try cross-compiling libVLC for WinRT. Refer to the [https://code.videolan.org/videolan/vlc-winrt README] file in the source folder for more information

==Build and Deploy==
* Open the VLC_WinRT solution in app/VLC_WINRT.sln
* Open Package.appxmanifest, and generate a test certificate. More information can be found in the [https://code.videolan.org/videolan/vlc-winrt/blob/master/README README] file in the source folder
* Click on Build Solution and then Deploy

==Additional Notes==
* If building fails with lots of errors referring to Windows SDK headers, installing Windows 8.1 SDK usually helps
* It helps to right click the specific project (eg: Windows 8.1 project ) and then click deploy rather than trying to deploy the whole solution
