The fact is unless you maintain these mappings by hand (unreasonable),
or use lavf (we're not), or your demuxer returns a lavc-friendly ID,
you simply cannot use libavcodec.
I think the best idea would be to have a more generic API for getting
various codec mapping tables, rather than a per-demuxer function. I
think you suggested this earlier.
Would you be against this?
