Just sharing that I’ve been surprized to see that some basic gstreamer pipelines streaming by default to localhost were no longer working in JP5.
Seems localhost is turnt into IPv6 localhost in udpsink, so receiver udpsrc should specify
gst-launch-1.0 videotestsrc ! nvvidconv ! nvv4l2h264enc insert-sps-pps=1 idrinterval=30 insert-vui=1 ! h264parse ! rtph264pay ! udpsink
gst-launch-1.0 udpsrc address=::1 ! application/x-rtp,encoding-name=H264 ! rtph264depay ! h264parse ! nvv4l2decoder ! nvvidconv ! xvimagesink
Or specify host=127.0.0.1 in udpsink for using IPv4.
Hope this helps.
