(Replying to both.)

This kind of metadata is basically for user info and things like tags.
It should NOT be used to export semantic/mandatory information about
the video stream.

To make it even worse, ffmpeg.c will happily put those tags into other
container/codecs, which means using metadata for this information will
likely produce broken files that can only be read by ffmpeg itself.
