Gstreamer gstsrc

Hi all.

I have been looking thro the web for an examples that I could learn on but I guess I do not know how to ask google with correct question. And I have just started with gst (I have done several simple pipelines).
I would like to receive multiple connections (from different ip addresses) on udpsrc (or similar). I would like to get sender ip address of the connection along with the stream and direct each (ip, stream) pair in separate processes. So each process will have IP info and stream. I would appreciate any knowledge you can spareā€¦

Best regards HD
