i suggest you some RTFM of docs/tech/libmpcodecs.txt

your codec implementation is messy at several points, misuse flags and so
on. it's on my TODO to reimplement/fix but i'm busy with G2 nowdays.

the best would be if theora codec could decode into memory allocated by
mplayer core, hopefully in Xv or video card's memory area.
