[Libav-user] How to add proprietary encoder like x264 to the FFmpeg

Thanks for your answer.  
About the x264, I didn't make my point cleary. Sorry about that. 
I have two more questions. 
1. In order to let livavcodec offer a wrapper for my special encoder, what do I need to do?
2. If my special encoder gets a wrapper from livavcodec or is added to livavcodec, 
   do I have to distribute the source code?
Thanks a lot.

There is no legal process, you send your patch to 
the ffmpeg-devel mailing list where it gets reviewed 
and will be committed once the review process is

Yes and no.
x264 is not a part of libavcodec, you may compile 
libavcodec so that it offers a wrapper for x264.

This doesn't sound correct / you are mixing things 
up here.
