By default the videotestsrc will generate data indefinitely, but if the num-buffers property is non-zero it will instead generate a fixed number of video frames and then send EOS.

This code seems fine but it doesn't relate to the console output you posted. Try testing your pipeline piece by piece with the command line gst-launch: gst-launch-1.0 -e -v videotestsrc ! udpsink host="127.0.01". connected to a fakesink first and then swapping in the udp sink, once you have it working in the command line mirror the command in code.
