Sounds like something that would need to be investigated in some more
detail, maybe there's a bug somewhere. In this setup h264parse shouldn't
really need to modify anything, it should be able to just pass through
the data as it comes in (assuming things are negotiated right and the
depayloader outputs byte-stream).
