Cannot read from resource - rstp steraming

Autonomous Machines Jetson & Embedded Systems Jetson Nano

Hello !!
I am trying to do realtime video streaming from jetson nano. For streaming, I used this.

~/gst-rtsp-server-1.14.1/examples$ ./test-launch "( nvcamerasrc sensor-id=0 ! video/x-raw(memory:NVMM), width=1920, height=1080, framerate=30/1, format=I420 ! nvvidconv flip-method=4 ! video/x-raw, width=720, height=480, framerate=30/1, 
format=I420 ! timeoverlay ! omxh265enc ! rtph265pay name=pay0 pt=96 )"
stream ready at rtsp://127.0.0.1:8554/test

For Playing, I used this.

gst-launch-1.0 rtspsrc location=rtsp://127.0.0.1:8554/test  ! 'application/x-rtp, media=(string)video' ! decodebin ! videoconvert ! ximagesink

And then I got the following error

Setting pipeline to PAUSED ...
Pipeline is live and does not need PREROLL ...
Progress: (open) Opening Stream
Progress: (connect) Connecting to rtsp://127.0.0.1:8554/test

Could not receive message. (Timeout while waiting for server response)
ERROR: pipeline doesn't want to preroll.

How can I solve that error?
Thanks.

Hi,
nvcamerasrc is deprecated. You shall use nvarguscamerasrc.

<b>nvarguscamerasrc</b> sensor-id=0 ! video/x-raw(memory:NVMM), width=1920, height=1080, framerate=30/1, format=<b>NV12</b>! nvvidconv flip-method=4 ! video/x-raw, width=720, height=480, framerate=30/1, 
format=I420 ! timeoverlay ! omxh265enc ! rtph265pay name=pay0 pt=96

Hello Thank you for your reply.
I changed as you mentioned and I got new error in playing side.

gst-launch-1.0 rtspsrc location=rtsp://127.0.0.1:8554/test  ! 'application/x-rtp, media=(string)video' ! decodebin ! videoconvert ! ximagesink

Hi,
Do you run both server and client on Jetson Nano? If your client is on another PC, you should replace 127.0.0.1 with IP of server.

I run both on same jetson nano.

Hi,
PLease run either

$ gst-launch-1.0 uridecodebin uri=rtsp://127.0.0.1:8554/test ! nvoverlaysink

or

$ gst-launch-1.0 rtspsrc location=rtsp://127.0.0.1:8554/test ! rtph265depay ! h265parse ! nvv4l2decoder ! nvoverlaysink

We have verified both pipelines.
