(You mentioned programs, as said, I may have 
misunderstand.)
In transport streams, audio and video streams 
typically belong to a program, see ffmpeg -i file.ts for 
an example.

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 
for more information.

See http://ffmpeg.org/doxygen/trunk/avformat_8h_source.html 
for the sources in question.
