vp8enc only supports I420, not AYUV. That might be one problem :)

On the receiver side, first of all check if you can receive any RTP
packets at all with something like
gst-launch-1.0 -v udpsrc multicast-group=127.0.0.1 port=5011 ! fakesink silent=false

This should tell you if packets arrive. If they don't there's something
wrong on the sender already. If they do iteratively build the pipeline
to check from which point things go wrong.
