Playing UDP multicast video generated by gstreamer

kunice
I am using gstreamer to generate a flow:
RPORT=11841
RCLIENT_IP=239.255.0.1

PORT=5000
CLIENT_IP=239.255.0.1

gst-launch-1.0 udpsrc multicast-group=${RCLIENT_IP} port=${RPORT} ! tsdemux name=demux demux. ! mpeg4videoparse ! omxmpeg4videodec ! nvvidconv ! 'video/x-raw(memory:NVMM), format=(string)I420' ! omxh265enc control-rate=2 bitrate=10000000 ! 'video/x-h265, stream-format=(string)byte-stream' ! h265parse ! rtph265pay mtu=1400 ! udpsink host=$CLIENT_IP port=${PORT} sync=false async=false

I start VLC and open the network stream "udp://@239.255.0.1:5000" and nothing plays. Can someone tell me what I am missing?

Does VLC expect MPEG TS, MPEG TS over RTP here ? I really doubt it
accepts single element stream in raw RTP.
