Well, it doesn't support gamma yet, and without that it will look real crappy.
Adding that with the yuv=4 method is tricky, and yuv=3 is working badly for me for reasons I don't understand.
Plus, it does not have RGB support, so more changes are needed to support that first.
After that, it should be just a matter of copy-pasting the shader that running with yuv=3 -v -v prints.
