I remember the last time I played around with the libmpeg3 video
provider, it always returned YUY2 as the required pixel format. How
about in the case of invoking mplayer for playback?

The CLE266 driver's default pixel format is YUY2. But I remembered that
I could not render an image of type RGB to a YUY2 surface. I have to
request an ARGB surface to do that. So, can surfaces with different
pixel formats coexist?

Forgive me that I am lost :-)
I'll try to read more and ask later if I still have problems.
