mpegvideoparse is missing timestamps on mpeg frames. This is needed if you want
to send this unstamped mpeg2 streams via rtp. (rtp timing goes corrupt)

Attached file can be used to demonstrate this problem. Decoders can succesfully
decode (and timestamp) this stream, so all necesary information is available.
