For the record, I was noted that people were previously against adding
HEVC to riff.c's lists as that would end up supporting HEVC in AVI,
which we would prefer not to see in the wild.

Thus I think the proper way of doing this would be to have the IVF
demuxer to have its own AVCodecTag list instead of using the global
RIFF list. This could be shared between the demuxer and muxer so it
doesn't get duplicated.

Best regards,
Jan
