Apart from endianness-aware ARGB64, what other formats would be good to have
for CineForm? Are there any worth being added to GStreamer for example?

Is CineForm always internally operating on some kind of (A)RGB, or can it also
operate on some kind of (A)YUV without the conversion between the two?
