Your pipeline is incomplete. The source will just receive data and try
to push the data to the next element but there is no next element.

You could try if this works:

  gst-play-1.0 udp://127.0.0.1:1234

This should work if the stream is typefindable (i.e. MPEG-TS over UDP).

For RTP maybe the cam has an in-built RTSP server you can connect to to
set up the streaming?

Otherwise you'll need a manual pipeline, something like

  udpsrc caps=application/x-rtp,media=video,encoding-name=JPEG,clock-
rate=90000 ! rtpjitterbuffer latency=200 ! rtpjpegdepay ! queue !
decodebin ! videoconvert ! videoscale ! autovideosink

Cheers
