Is this a necessary thing for some deep reason? Or can it be easily
changed? (Not asking you in particular but the list as a whole)

If the change to the codecs is not easily possible, would it be good
enough to check out which codec is in use and then disable/enable the
workaround based on that?

This problem is really sort of inconsequential for "playback" -vo's but
for the streaming -vo's it's ugly.
