There's no easy way to find the name of pix formats automatically, but if 
you look for a file named gl.h on your computer, you can find that it 
contains 0x85b9 on the same line as it says #define GL_YCBCR_422_APPLE. I 
suppose that this is what GEM uses when it's in "YUV mode" on OSX. (YCBCR 
is another way to say YUV).

Therefore you need to use [pix_rgba]. (GF doesn't do this automatically.)

I could put a better error message, but I'd rather make it do an 
automatic conversion, when I get to address the issue (probably in 9.12).

It's normal, as the movie decoders are completely different, so, they 
don't necessarily have the same abilities (or at least, not the same 
defaults).
