YV12 will help for most users, but not for me :(

See my test results:

This is the only case, when ff wins.
                                                                   ^^^^^^^
still not acceptable for 16.6 seconds of a movie


if still in 32 bpp but using -bpp 24

now it's slower (yes, not too much difference) (and same as above ff)

things get worse in real 24 bpp

well, my time is up and I saw, that jkeil commited some optimization to
libavcodec, so I'll recompile mplayer, rerun my tests and after weekend
I'll publish them :)

Bye
Tibcu

and have a nice weekend at Balaton, Arpi! :)
