changing rtp capabilities

[Saurabh Sabnis]

I mentioned *clock-rate* by mistake, I was actually talking about only the
random properties such as *seqnum-base* and *ssrc* which according to RTP
should be random but I want to do something for which I require them to be
a particular value that I can assign.
I tried using gst_caps_new_simple and then link_filtered to
