Hi,

extremely in late, hopefully you've already fixed the implementation,
btw here's my pov.

if the server uses a session initiation protocol (I assume you're
using RTP) it may be possible to drop such a requirement.

for the receiving side, you can use uridecodebin:

http://www.gstreamer.net/data/doc/gstreamer/head/gst-plugins-base-plugins/html/gst-plugins-base-plugins-uridecodebin.html

then you can listen for the pad-added signal and dynamically connect
encoder, payloader and rtpbin/udpsink.

In case you want to use a session initiation protocol for the sending
part, you may be lucky and find an already existing implementation
(e.g. http://people.freedesktop.org/~wtay/) or implement it by your
own.
