RTSP Could not open resource for reading

steven.sparks · June 1, 2023, 3:45pm

Orin Jetpack 5.0.2
Setting up RTSP server with:

$ ./test-launch “v4l2src device=/dev/video0 ! video/x-raw, width=640,height=480,format=(string)YUY2,framerate=30/1 ! queue ! nvvidconv ! video/x-raw(memory:NVMM),width=640,height=480,format=(string)NV12 ! nvv4l2h264enc bitrate=912000 ! video/x-h264, stream-format=(string)byte-stream ! rtph264pay name=pay0 pt=96”
stream ready at rtsp://127.0.0.1:8554/test

Note: I’m not seeing the blue lights on the camera that I normally see. However, when I run
the jetson-inference video-viewer, camera works as I expected:
$ video-viewer /dev/video0 rtsp://127.0.0.1:8554 --input-codec=mjpeg --output-codec=mjpeg --bitrate=1000000

Check network to ensure test-launch process is running:

$sudo ss -ltnp
State        Recv-Q   Send-Q      Local Address:Port    Peer Address:Port    Process  
LISTEN       0        5           127.0.0.1:8554        0.0.0.0:*            users:(("test-launch",pid=8748,fd=4))

Reading from port:

steven@development-orin:~$ gst-launch-1.0 rtspsrc location=rtsp://127.0.0.1:8554/test latency=0 ! rtph264depay ! h264parse ! nvv4l2decoder ! nvvidconv ! xvimagesink sync=0

Any ideas? Thanks!!!

May be because you’re streaming RTPH264 but you’re trying to read as if it was RTPH265.
Try on receivert side:

st-launch-1.0 rtspsrc location=rtsp://127.0.0.1:8554/test latency=0 ! rtph264depay ! h264parse ! nvv4l2decoder ! nvvidconv ! xvimagesink sync=0

If this doesn’t work out, post the formats of your camera with:

# v4l2-ctl is provided by apt package v4l-utils
v4l2-ctl --list-formats-ext

Modified previous entry with code change to 264, still has issue. Thanks for the help.

Honey_Patouceul · June 1, 2023, 4:09pm

With H264 format, you may try:
./test-launch “v4l2src device=/dev/video0 ! video/x-h264, width=640, height=480, framerate=30/1 ! queue ! h264parse ! rtph264pay name=pay0 pt=96”

Note that you omitted the double quotes for test-launch.

First try to read camera feed and display (assuming you have a local monitor and GUI running on Jetson).
Try the following command and post the output of the first failing one if any.

gst-launch-1.0 -v v4l2src device=/dev/video0 ! fakesink

gst-launch-1.0 -v v4l2src device=/dev/video0 ! video/x-h264, width=640, height=480, framerate=30/1 ! fakesink

gst-launch-1.0 -v v4l2src device=/dev/video0 ! video/x-h264, width=640, height=480, framerate=30/1 ! h264parse ! nvv4l2decoder ! nvvidconv ! autovideosink

steven.sparks · June 1, 2023, 4:38pm

Re-ran test-launch with double quotes. Result seems the same. But I will include for now on.

Ran the 3 tests. All functioned correctly. The last one displayed video on my screen.

Honey_Patouceul · June 1, 2023, 4:43pm

That’s good news. Now try:

gst-launch-1.0 -v v4l2src device=/dev/video0 ! video/x-h264, width=640, height=480, framerate=30/1 ! h264parse ! rtph264pay name=pay0 pt=96 ! fakesink

If this runs, you may have the server running in one terminal:

./test-launch "v4l2src device=/dev/video0 ! video/x-h264, width=640, height=480, framerate=30/1 ! h264parse ! rtph264pay name=pay0 pt=96"

and in second terminal run the client:

gst-play-1.0 rtsp://127.0.0.1:8554/test

When client connects, post errors if any from the first terminal (server) and from second terminal (client).

steven.sparks · June 1, 2023, 4:59pm

The first test was successful
When I ran the 2nd test I received the standard “stream ready at rtsp://127.0.0.1:8554/test”
The 3rd test had issues:

steven@development-orin:~$ gst-play-1.0 rtsp://127.0.0.1:8554/test
Press 'k' to see a list of keyboard shortcuts.
Now playing rtsp://127.0.0.1:8554/test

steven.sparks · June 1, 2023, 5:56pm

@DaneLLL Are you aware of a bug preventing ORIN RTSP?
Any suggestions?

Thanks!

steven.sparks · June 5, 2023, 5:40pm

I set
$ export GST_DEBUG=“*:6” then
re-ran
$ ./test.launch “pipeline” 2>err.text

Reviewed the output, nothing eventful shows. I didn’t mention this before, the camera lights show during the gst-launch-1.0 test but not when using ./test.launch.

I submitted a question at freedesktop.org forum 1016 and submitted the error output. I was initially asked to upgrade gstreamer.
I investigated on the Nvidia forums on the process, but seems going past Gstreamer 1.16.3 is not supported.

steven.sparks · June 5, 2023, 11:49pm

Works now.

I had changed the receiving object name in test-launch from “test” to “my_stream”. Once I changed back and re-compiled, then ran both, a window with video appeared.
