''VideoLAN tries to be a mentoring organization''

== 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 {{VLC}}.


=== VLC media player ===
{{VLC}} is a cross-platform Multimedia player, and encoding and streaming 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 4 millions from the main website (not including third-party distributions (Linux)), which means about 30 million people have downloaded VLC 0.8.5 from the main website!

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

=== Summer of Code ===

If selected and developed, SoC ideas will be included in the VLC 0.9.1 or any later version release, and covered by the GPL licence.

=== Ideas ===

'''''Read this'''''

We (the VideoLAN team, and [[User:J-b|jb]], the author of this page) have split this page in three lists of ideas:
* The ''main ideas'' are the ones we would like to focus on, and seem to be key projects for VLC and a lot 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.
* Original good ideas will be valued. Last year, half of the ideas were given by students. [[Mini_Projects]] has some ideas too.

We don't want to impose anything. This is free and Open Source software. Last year, many projects were external ideas.

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

And on IRC channel, you can have even more ideas.

== Main ideas ==

=== Fullscreen Controller ===
This project is easy to describe, it would provide a fullscreen controller for Linux/Unix and Windows, as {{VLC}} already has on Mac OS X version since 0.8.6.

It should be draggable, clickable and support the classical control buttons to control VLC playback in fullscreen mode.

With this project, which is not too long, there should be some related work on Vout (Making sure the video output does not close and reopen between files for example...)

This project needs basic C++ knowledge. Qt knowledge would be a plus.

=== 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 some knowledge of C

=== MTP Device Service Discovery ===
This projects consists of adding support for finding and reading content from attached USB MTP (Media Transfer Protocol) devices,
such as the Apple iPod, as a Service Discovery and input plugins for VLC.

This project might need improvements in the Service Discovery subsystem for hotplug.

=== QuickTimeVR Playing ===
This project deals with integration QuickTimeVR inside VLC using work from FreePV (SoC 2007).
This project will require some modification on image handling inside VLC.

=== UPnP media service ===
This project involves adding support for advertizing the stream on the LAN using Universal Plug'n'Play A/V  / DLNA.

== Other Ideas SoC 2008 ==

=== QTKit access ===
QTKit-based access module for OS X (allowing input from USB / FireWire cameras, audio devices, camcorders, tape recorders [, ...your favourite here] ). GUI Integration.

''Proposed mentor: BigBen'' (backup feepk)

=== Leopard integration ===
- a QuickLook-plugin for OS X Leopard 
- Video Output animations
- VLC_app (VLCKit based) improvements.
- VLCKit oneclick-Streaming Server implementation.

=== iPhone / iPod touch port ===
Now that the SDK is approaching, we might consider the port of VLC to the iPhone / iPod touch platform. Obviously, this project requires the student to own such a device.

=== Matroska (mkv) muxing ===

This project is about writing a mkv muxer for VLC with advanced support (chapters, multiple audio and multiple subtitles, etc...) like when you need to rip or archive a DVD.

FFMPEG project has a similar project, and we could use the libavformat muxer and adapt ourselves, but we are not sure if we will be able to use therefore all the advanced features.

''robUx4 can do the mentoring. He has already wrote the demux and has worked for matroska, so knows it very well.''

=== WinCE port ===
The WinCE port has been broken for some time now before 0.8.4. Repairing the builds of all the external libraries build and making VLC build and work should take some time :D

Then a rework of the interface should happen.

''Proposed mentor: djc.''

=== Automated threading error detection ===
VLC is heavily multithreaded.
This project would involve extending the VLC threading APIs to provide better run-time consistency checks, and possibly proof of correctness. This could be similar to the lock consistency checking in the Linux kernel, albeit more simple - VLC does not have to deal with interruptions neither atomic operation and has fewer thread and synchronisation constructs.

This project requires working knowledge of the C programming language and POSIX threads.

''mentoring would be done by courmisch''

===  GUI interfaces for the browsers plug-ins ===
This project focuses on adding interfaces to our browser plug-ins, in order to have, in the web pages embedded mode, buttons to control {{VLC}} as in WMP or Youtube player. These buttons need to be cross-platform and cross-browsers.

The second part of this project aims to provide a replacement for all preconfigured media players embedded in web pages, if possible.
 
For example, when a webpage asks for WMP embedded plugin, youtube player, quicktime player or any other, VLC would detect the stream and display it. This would mean less CPU needed than Flash based players...

This project may need to work in concert with some improvements on the cache handling module access.

The look of the interface should not be a problem (it can be added later on).

''Proposed mentor: dionoea''

=== Vista acceleration and DirectX improvements ===
Current versions of {{VLC}} have a lot of problems on Windows Vista (check the forums for specifics).

We need support for the new EVR (enhanced video renderer) in Windows Vista, and make it the default Video Output module for that OS.

See [http://download.microsoft.com/download/5/b/9/5b97017b-e28a-4bae-ba48-174cf47d23cd/MED134_WH06.ppt Windows Vista Video Pipeline Architecture And Implementation] and [http://msdn2.microsoft.com/en-us/library/ms788119.aspx DirectShow Improvements in Vista]

Some rework and enhancements of the DirectX and Direct3D Video Output modules may also be necessary.
