In theory it can work with any demuxer / stream. But in the real world
there is sowe limitations :(( Some stream (mainly dvd and vcd) use a
global var to enable themself so for the second stream it will just reopen
the same stream again.
There is sometimes the same problem with the demuxers, that's why i changed
rawaudio to enable itself only if the user forced the demuxer type (and
changed the on option to set the demuxer type instead of his dedicated var).
Finnaly the demuxer must be able to perfectly handle the 'demux only the
audio stream' case to be used as audio stream, and it must be 100%
reentrant if you need 2 time the same demuxer.

So as you see that's a lot of if but all well made stream / demuxer
should just work. If you find some demuxer combination that doesn't
work i can take a look it.
