I checked your pipelines and they indeed will not work:
You sender pipeline:


is missing a demultiplexer element, e.g. qtdemux:


When running this pipeline, as said before, you will find the correct
application/x-rtp caps shown at stdout. You have to copy these caps over to
the receiver pipeline. Otherwise, the receiver pipeline has no means to
figure out what it is receiving.



Btw, you could have used gst-inspect-1.0 fdsrc to see that fdsrc does not
have a caps property.

Example of rtp h264 caps:
"application/x-rtp, media=(string)video, clock-rate=(int)90000,
encoding-name=(string)H264, packetization-mode=(string)1,
profile-level-id=(string)42c01e,
sprop-parameter-sets=(string)"Z0LAHtwLQ9sBEAAAAwAQAAADAyhA\,aM48gA\=\=",
payload=(int)96, ssrc=(uint)2323517954, timestamp-offset=(uint)2162767804,
seqnum-offset=(uint)16555, a-framerate=(string)25"
