RTP is live, so when you PAUSE such a pipeline bad things will happen.
Take a look at rtspsrc for a way of how you can implement pausing
nonetheless. It requires two-way communication with the sender though.

However the easiest solution in your case would be to just put a valve
element into your pipeline, and whenever you want to "pause", you would
make it drop all packets.
