(You mentioned programs, as said, I may have 
In transport streams, audio and video streams

avconv contains several hundred known bugs not present in 
FFmpeg, some of them security-relevant, please understand 
that we cannot support it here.
See http://blog.pkh.me/p/13-the-ffmpeg-libav-situation.html
