yuv422p9le, gbrp, gbrp9be, gbrp9le, gbrp10be, gbrp10le, gbrp16be,
gbrp16le

don't have a corresponding fourcc, so for example cannot be stored in
the NUT container (and the output created by the lavfi test can't be
properly read), unless we add some specific fourccs for them, like we
did in the past.
