{{x264}} is the most popular open source video compression software in the world, used worldwide for applications such as web video, television broadcast, and Blu-ray authoring. It outclasses practically all commercial implementations both speed and compression-wise. While not actually part of VLC or ffmpeg, it is a major library used by both, licensed under the GPL. Due to its popularity in the commercial world (for example, Youtube and Facebook rely on it), many companies have offered bounties in the past for features and improvements that they found useful.

Google Summer of Code 2010.

This wiki page covers the attempt by the VideoLAN project to act as a mentoring organization for Google Summer of Code, in order to improve VLC media player, x264, the H.264 video encoder, and VLMC. The accepted projects are seen on a separate page.


Introduction & Information

This wiki page covers the attempt by the VideoLAN project to act as a mentoring organization for Google Summer of Code, in order to improve VLC media player and x264, the H.264 video encoder.

VideoLAN was a mentoring organization in 2007, 2008 and 2009.

  • This page list the ideas for VLC.
  • There is also a separate page for project ideas for x264: SoC x264 2010.

If you are a student, please read the rules and advice.

VLC media player

VLC media player 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 media player is downloaded at an approximate monthly rate of 5 millions from the main website and that's not including third-party distributions (Linux)!

You can find more information on VLC on Wikipedia or on this wiki.

x264

x264 is probably the most popular open source video compression software, used worldwide for applications such as web video, television broadcast, and Blu-ray authoring. It outclasses practically all commercial implementations both speed and compression-wise. While not actually part of VLC or ffmpeg, it is a major library used by both, licensed under the GPL. Due to its popularity in the commercial world (for example, Youtube and Facebook rely on it), many companies have offered bounties in the past for features and improvements that they found useful.

Summer of Code

If selected and developed, SoC projects for VLC will be included in later releases; SoC projects for x264 will be included in the main tree of the project.

All projects are covered by the GPL licence. (v2+)

Ideas for VLC and VLMC

Read this

This page is split in three lists of ideas:

  1. The main ideas are what seem to be key projects for VLC and should be more thrilling than the other ones; we have assigned a potential mentor to each of these.
  2. Phonon ideas, for KDE/Phonon work.
  3. The other ideas are less detailed but could be good ideas too.
  4. VLMC ideas
  5. Mini_Projects are short-span projects which can be given as Qualification tasks or extended to be Full Summer of Code project.
  • Original good ideas will be valued. Last year, half of the ideas were given by students. We don't want to impose anything. This is free and Open Source software.

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

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

Ideas for x264

For x264 ideas, please see SoC x264 2010.

Key VLC projects

Shader support for DirectX/OpenGL

A lot of video post-processing such as RGB-YUV conversion can be accelerated by using GPU and Shaders. Implement support for this in the DirectX and OpenGL drivers for Windows and OpenGL for other platforms. (coding in C and custom shader creation).

Proposed mentor: Fenrir

Rewrite Matroska demuxer

This project is for advanced multimedia coders.

If you are well introduced in muxers/demuxers and know pretty well how matroska is done, this is for you.

You will very likely need to use an existing open source demuxer, for example the libavformat demuxer (written in C)

If you are fast enough, the muxer side would be cool.

Code will be in C.

Proposed mentor: Fenrir

Audio Filters

We are looking for a skilled audiophile that knows a lot about audio theory and practice:

  • to create or implement new algorithms, like SRS WoW or other 3D effects
  • to work on channels mixing,
  • to work on tracks mixing,
  • to create 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 will be interesting.

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

Proposed mentor: 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 Personnal 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: dionoea

Enhanced DVD Audio support

This project is quite simple, it speaks about supporting DVD-Audio.

VLC already decodes .aob files, but doesn't handle the DVD-Audio extensions, nor the decryption.

The student should be passionate about Audio and have already one DVD-Audio Disc.

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

Proposed mentor: jpsaman

Interface for VLC on Mobile phones

VLC uses Qt for its main interfaces on desktop systems.

It would be nice to have an UI for embedded systems like Windows Mobile.

Using Qt or EFL would be a good idea.

This project is a code project, require knowledge of C or C++.

Proposed mentor: ILEoo

Blu-ray enhancements

We need Menu/Navigation support. VLC Currently supports Bluray chapter playback but still needs menu support.

BD-Live and BD-Java support would be interesting.

Proposed mentor: jb

RTMPdump

Integrate the RTMPdump library to play rtmp and rtmpe streams.

Proposed mentor: jpsaman or ivoire

UPNP DLNA Server and Client

Provide SD module for DLNA shares being compliant with DLNA specification as well as software (say, mediatomb, xbmc, etc) and hardware implementations.

Provide DLNA plugin for DLNA server compliant with opensource (xbmc, djmount, etc) and proprietary (PS3, xbox360, etc) DLNA clients.

Be smart enough to provide "presets" for known DLNA media clients with limited features (PS3, for instance) which require additional quirks or hacks or items to be transcoded.

Proposed mentor: ivoire or Meuuh

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.
  • memcpy implementations in SSE* and MMX (see modules/misc/memcpy/fastmemcpy.h)
  • 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.

Proposed mentor: jb

Set of lua extensions

With VLC 1.1, extensions can be written for VLC in lua.

This project deals with writing many new extensions (between 20 and 30) during the summer for the most interesting features we can find on the Net.

Proposed mentor: jpeg

Phonon ideas

High-Level Capture API for Phonon (read: Webcam Support)

Phonon is a multimedia abstraction layer, developed by the KDE project.

It features multiple backends, including VLC.

The goal of this project would be to create an API to allow Phonon application to display and access input devices, like webcams. The API would then be implemented in phonon-vlc and other backends, such as phonon-gst, as time permits.

Proposed mentor: Ian Monroe

Phonon-VLC improvements and test

This project would be about improving the long-term quality of the Phonon-VLC backend:

  • Improving VLC Phonon backend, implementing lacking API,
  • Fixing the Phonon CTest-based tests,
  • Implement more tests,
  • Run the tests on windows,
  • Implement cool features like DVD-Audio or Blu-Ray support (should be pretty easy),

Proposed mentor: Ian Monroe

Phonon API for implementing effects in applications

This would be about fleshing out an API for letting applications make their own effects (get data out, and push data back). Might be useful to use AudioDataOutput.

VLMC (VideoLAN Movie Creator) ideas

Add Jack support

This is an often request features.

It would be nice to be abble to export VLMC sound output to another program, or reading from another program output instead or reading from an audio file.

This project includes core VLMC programming, to allow the selection of an audio input/output, as VLMC only supports file input, and doesn't really deals with output. Once this is done, it will require some GUI programming, to create some configuration widgets.

Proposed mentor: chouquette

Adding custom widgets

Many widgets are not good enough right now. Correcting those widgets, provide alternative widget so VLMC better fits with the video editing needs.

Many widgets can be rewritten : Import, Library, Clip property... be creative ! Proposed mentor: etix

Youtube integration

As VLC can read a Youtube input, so does VLMC. However, this is not implemented at this time. This project would consist in : importing media from youtube , allowing direct export to youtube, directly export to youtube, instead of a file.

Proposed mentor: chouquette
