<ubitux> i can't even contribute to that
<ubitux> except saying "don't"
<ubitux> should i send revert patches?
<DonDiego> no, you should shut up or go away
<DonDiego> if you want to influence this project, contribute
<DonDiego> if you don't want to contribute, don't complain

They can. No one is banned there. Just follow FFmpeg development like most of

We keep API synchronized the better we can already. Libav doesn't care, and
doesn't want to care except if it can breaks compat. I can quote IRC if needed.

Yes, of course ffmpeg is for hacks.
