Libav contains a set of libraries with extensive (Doxygen) documentation for programmers. However, that documentation is spotty and incomplete in parts. Go read the code, understand it and fill in some of the missing bits and pieces.

This task is considered complete in those cases:

- A set of 15 function is throughly documented

- 2 codecs or demuxers get documented and put in the right group

- You provide a custom layout for doxygen so it looks more in line with the rest of libav.org website.
