The notion of "this stream needs to be combined with another one for
presentation" seems more general than just tiling video, could just as
well describe a set of audio tracks to be mixed together.
That's why i stated it's for video. For audio there's
AV_DISPOSITION_DEPENDENT.
And since we're running out of easily usable disposition bits, we
shouldn't waste them. How about AV_DISPOSITION_SUBSTREAM?
Maybe we could redefine and reuse AV_DISPOSITION_DEPENDENT for this?
