Your are RTP-payloading the MPEG-TS stream from mpegtsmux. That's fine,
but not strictly required. You can also send the MPEG-TS stream
directly without RTP payloading (in which case use mpegtsmux
alignment=7).

If you RTP payload the stream, the receiver side should look something
like:

  udpsrc ! rtpjitterbuffer ! rtpmp2tdepay ! tsdemux ...

and if you don't RTP payload the stream, something like:

  udpsrc ! queue ! tsdemux ! ...  should work.

Cheers
 Tim
