	libavformat is the interface of FFmpeg that is responsible for splitting apart encoded audio and video data from multimedia files (demuxing) and putting it together in new multimedia files (muxing). While libavcodec -- the FFmpeg component that encodes and decodes audio and video data -- enjoys [http://ffmpeg.~~sourceforge~~.~~net~~/projects.~~php~~ widespread use among an impressive array of multimedia projects] libavformat has not seen the same level of adoption. This task would entail investigating how to improve the libavformat API, how it interacts with client applications and input layers, developing proof of concept code for a new API and working to port existing muxers and demuxers to the new API.		libavformat is the interface of FFmpeg that is responsible for splitting apart encoded audio and video data from multimedia files (demuxing) and putting it together in new multimedia files (muxing).

Traditionally, top applications are fairly detailed. Look at this application for inspiration [http://vfer.sourceforge.net/cgi-bin/index.cgi?page=writeup].

 == VC-1 ==
 [[VC-1]], a.k.a. Microsoft Windows Media Video 3 or 9, is widely used and should see even wider use due to the introduction of [[HD-DVD]]. The format for this codec is open and known, but so far unimplemented in FFmpeg. This task entails implementing the VC-1 codec based on the emerging [[Understanding VC-1|open specification Wiki document]] and forthcoming roadmap. This is a big task but will have very clearly defined milestones, e.g., the first major goal is to decode I-frames, and to get that point there will be a number of smaller goals, each with its own set of unit tests.

 == AAC ==
 AAC is quickly becoming the new MP3. FFmpeg wants its own independent implementation. This task entails implementing a new, optimized AAC decoder in a similar manner as outlined in the [[FFmpeg Summer Of Code#VC-1|VC-1]] section, based on the emerging [[Understanding AAC|open specification Wiki document]].
