Jetson opencv to rtsp stream

Hi,

I’m stuck trying to stream video from opencv python to rtsp

In python I’ve the following code to capture from the camera and convert to h265

framerate = 25.0
out = cv2.VideoWriter("appsrc ! videoconvert ! omxh265enc preset-level=3 ! rtph265pay name=pay0 pt=96 ! udpsink host=127.0.0.1 port=5555", 0, framerate, (624, 352))

In the command line I start the test-launch app with the following line

/test-launch --gst-debug-level 3 "udpsrc port=5555 ! application/x-rtp ! rtph265depay ! rtph265pay name=pay0 pt=96"

But when I open vlc rtsp://localhost:8554/test I cannot view the video and get this warning
