Google Summer of Code 2008.
- 1 Introduction & Information
- 2 Main ideas
- 3 More Ideas
- 4 Mini Projects - More ideas
- 5 Questions? Contact us?
Introduction & Information
- This page list the ideas for VLC.
- There is also a separate page for project ideas for the x264: SoC x264.
VLC media player
VLC media player 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 media player 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!
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.
We (the VideoLAN team, and 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.
For x264 ideas, please see SoC_x264.
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
Proposed mentor: User:Pdherbemont (backup: courmisch)
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.
This project needs a student to have a MP3 player device...
Proposed mentor: funman (backup jb)
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, before starting.
Proposed mentor: dionoea (backup Yuval Levy)
Interested students: User:Plouj
UPnP media service
This project involves adding support for advertizing the stream on the LAN using Universal Plug'n'Play A/V / DLNA.
Streaming to the PS3 can be one achievement of it.
Using libdlna might be a good idea.
Having a cross platform solution is almost a must.
Proposed mentor: funman
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 media player 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
This project is easy to describe, it would provide a fullscreen controller for Linux/Unix and Windows, as VLC media player already has on Mac OS X version since 0.8.6.
- be draggable,
- be clickable,
- support the classical control buttons to control VLC playback in fullscreen mode,
- have all the VLC functionalities in it.
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.
This project should be doable by any serious student in a summer.
Proposed mentor: jb (backup atmo)
This project means to deal with building a QTKit-based access module for OS X (allowing input from USB / FireWire cameras, audio devices, camcorders, tape recorders [, ...your favourite here] ).
This project needs also GUI Integration.
Proposed mentor: BigBen (backup feepk)
- a QuickLook-plugin for OS X Leopard
- Video Output animations
- VLC_app (VLCKit based) improvements.
- VLCKit oneclick-Streaming Server implementation.
Proposed mentor: pdherbemont, feepk
iPhone / iPod touch port
Port VLC to the iPhone / iPod touch platform.
This project does not necessarily require the student to own such a device due to the availability of a simulator as part of the official SDK, although it is probably helpful.
Proposed mentor: pdherbemont (backup feepk)
Vista acceleration and DirectX improvements
Current versions of VLC media player 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.
Some rework and enhancements of the DirectX and Direct3D Video Output modules may also be necessary.
Proposed mentor: atmo
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
Assembly optimizations in VLC
If you are fond of writing ASM and you are fluent in MMX/SSE2, there are many interesting things in VLC to speed up.
- memcpy implementations in SSE2
- video filters ASM speedups
- audio filters ASM speedups
- Porting other ASM video filters to VLC.
- Profiling VLC.
This project needs some good ASM knowledge and good C experience.
Proposed mentor: jb, Dark_Shikari"
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.
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.
Better video output integration.
Better skin support.
See with jb
Make SVCD's work. Menu selection, navigation and hot spots.
Proposed mentor: rockyb.
Mini Projects - More ideas
Original ideas will be rewarded.
- Visualisation improvements (libprojectM implementation ? )
- Video rework.
