yv12 ~= i420, but U,V planes swapped. soit's very easy to convert etween.

hmm. i'll look at it

no no
i don't want to touch codecs.conf...
i had an idea, to make an option: codecs_priority=ffdivx,mpeg12,h263xa,...
so users can force a given order of codecs. it could default to compiletime
setting generated by configure.
