Definitely. YV12 and I420 should be supported, since this is what almost
all codecs output. YUY2 will trigger a YUV 4:2:0 -> YUV 4:2:2
conversion.

I would recommend to build a list of formats, the X11 driver can handle and
use gavl_pixelformat_get_best() to choose the one with the lowest conversion
overhead.

BTW are you planning to support OpenGL playback as well?
