Since it is set for e.g. webm muxer we should make it possible to test such streams with framecrc, too. Though the primary reason is that this allows the H.264 tests to not run into this check when fixing raw video encode to pass pts values on. Signed-off-by: Reimar Döffinger <Reimar.Doeffinger@gmx.de>
