Nope, you can't access the HW in OSX. SDL uses the "Quartz"
engine, and the "QuickTime" stuff for YUV overlay. Similar
in spirit to X11 and Xv, respectively.

Except that libSDL doen't handle 2VUY (or I don't understand
the code :-), so you have to let QT do the translation.

MPlayerOSX is a GUI wrapper around a regular mplayer binary.

I've never found a way to display anything with mplayer
on MacOSX except with -vo sdl. Even X11 doesn't work
as 'RGB32 is not supported on Big-Endian System'. Not that
it's of any importance, as it would be much slower than
YUV overlay in SDL anyway.
