This is not the first decoder to output YCoCg, I have H.264 files with
that as well. Just because swscale cannot convert that doesn't mean we
should be doing anything but non-native output from a decoder. My
playback chain can support that just fine.
Feel free to contribute YCoCg conversion to swscale to resolve this
for "the users".
