Gst_rtsp_server error and VLC not playing stream

Hi,

I cloned the gst_rtsp_server at https://gitlab.freedesktop.org/gstreamer/gst-rtsp-server onto my TX2 and am trying to stream from an nvarguscamerasrc.

However, when we run this using the test-launch:
./test-launch "nvarguscamerasrc ! ‘video/x-raw(memory:NVMM),width=(int)320,height=(int)240,format=(string)NV12,framerate=(fraction)15/1’ ! omxh264enc name=omxh264enc control-rate=1 ! video/x-h264,profile=baseline,stream-format=(string)byte-stream ! h264parse ! rtph264pay name=pay0"

we get the output that the stream is ready at rtsp://127.0.0.1:8554/test

However, when we try to access the stream at rtsp://(TX2 IP):8554/test, we get this on the TX2 side:
(test-launch:7038): GStreamer- **CRITICAL** **: 22:21:01.773: gst_element_make_from_uri: assertion 'gst_uri_is_valid (uri)' failed

and this on the client machine side:
gst-launch-1.0 rtspsrc location=rtsp://10.137.88.33:8554/test latency=100 ! queue ! rtph264depay ! h264parse ! avdec_h264 ! videoconvert ! videoscale ! video/x-raw,width=640,height=480 ! autovideosink

The bizarre thing is a few months ago, this pipeline was working (or somehow I was able to get the RTSP stream on my host machine using the same process). Does anyone have any advice on what could be going on?

GStreamer core version (TX2): 1.14.5
GStreamer core version (client machine): 1.16.2
rtsp-server repo checkout: 1.14

Thank you so much!

Hi,
You may try nvv4l2h264enc. Please refer to

You may replace videotestsrc with nvarguscamerasrc and try.

Hi, when we run this pipeline with nvarguscamerasrc, we get this result:

./test-launch 'nvarguscamerasrc ! nvvidconv ! nvv4l2h264enc ! h264parse ! queue ! rtph264pay name=pay0 pt=96 audiotestsrc ! voaacenc ! queue ! rtpmp4apay pt=97 name=pay1'

And when we run this pipeline on the client machine, we only get a gray screen (when we run VLC, we don’t get anything at all - no errors, but also no video popping up).

gst-launch-1.0 rtspsrc location=rtsp://10.137.88.33:8554/test latency=100 ! queue ! rtph264depay ! h264parse ! avdec_h264 ! videoconvert ! videoscale ! video/x-raw,width=640,height=480 ! autovideosink

Do you have any advice?

Thank you so much!

Hi, thanks again for your help! I have an update:

We actually got the RTSP stream to work using gstreamer and not the gst-rtsp-server.

On the camera end:
gst-launch-1.0 nvarguscamerasrc ! 'video/x-raw(memory:NVMM), width=1920, height=1080, framerate=30/1' ! omxh264enc control-rate=2 bitrate=4000000 ! video/x-h264, stream-format=byte-stream ! rtph264pay mtu=1400 ! udpsink host=$CLIENT_IP port=8554 sync=false async=false

On the client end:
gst-launch-1.0 udpsrc port=8554 ! application/x-rtp,encoding-name=H264,payload=96 ! rtph264depay ! h264parse ! queue ! avdec_h264 ! autovideosink sync=false async=false -e

It’s now streaming with very little latency and looks great on the client end.

Thanks again!
