What makes you think this will be set correctly with -ovc copy?
Also that still seems very unlikely to me to be what most people
want when they use -ovc copy, so what is really the point of adding such
a hack?
And lastly, such a change would break the only case where -ovc copy
_can_ work perfectly, namely all-keyframe video (e.g. MJPEG).
