if only teh codec changes, it's easier, if the filemormat too, then it's
more difficult.

one way is just restaring the playback process at codec changes (like you
have multiple files in a playlist) but it may have visual effect/flicker
depending on the vo driver being used.

for using multiple codecs for constant demuxer, and switching between them
in-stream, you should init all the codecs at the beginning and make some
switching when the decoder function is called.

the libmpcodecs part should be reentrant (maybe except the win32 codecs)
but i'm afraid the others, especialy the mplayer.c code needs some design
changes.
