yes, i understood. and i like the idea! implement it!
some hints:
when seeking, you should call seeking function of the sub-demuxers.
call first the video one, then get back its position and seek the audio to
thet position. why? audio sterams are usually seekable to any position,
while video depends on keyframes.

i had similar idea, but i wanted to make a demuxer stream, a stream type
which reads from a second demuxer instead of a real stream.

so: stream -> demuxer1 -> stream -> demuxer2 -> decoders

i need it for mpeg-TS support (mpeg-PS muxed into mpeg-TS format)
