Thanks. > I don't think there's any concise way of checking such conditions... you'll > probably have to do something like a list of "codes" (v410, v210, raw) and > some sort of sanity check for track->par->format to confirm is is YCbCr. > Maybe someone knows better than myself. I see that although it’s mandatory for uncompressed YUV, there’s no constraint to not use it otherwise, so I think I’ll proceed with just a check for MODE_MOV. I just checked ffmbc’s movenc.c and it also only checks for MODE_MOV.
