Well, that makes no sense. It's too limiting in all aspects.
Your problems comes very close to that of titles in a DVD/Bluray:
trailers often have one video, but then the main movie might have
mutli-angle ideo, multi-language subtitles/audiostreams, etc. The
codecs can be different between titles (LPCM for the main concert, but
simple ac3 for the trailers, or whatever; for BR, the video codec
might change also).
The solution to the.problem of "how do I support multiple streams in a
playlist" and "how do I support multiple titles in a DVD/BR disc" is
likely the same, and I don't know if hacking AVFormatContext is the
right way forward...
