Hi,
It is not clear about building a media server. You may share more information about what you would like to do. A general case is to launch RTSP server through test-launch. You may refer to

We are deprecating omx plugins and you can run

./test-launch “videotestsrc ! nvvidconv ! nvv4l2h265enc ! h265parse ! rtph265pay name=pay0 pt=96”

Hi,

GStreamer Daemon uses server/client model to be executed. make sure to run first gstd and then gstd-client in separated terminal

Example:

Terminal 1

gstd -D

Terminal 2

gstd-client

Go to the GStreamer Daemon documentation for more information

Hi,
RTSP server cannot be launched in gst-launch-1.0 command. You would need to build and run test-launch application.

Hi

Could you share your pipeline please?

Seems there is something missing in it.

Thanks

HI9 aphillopso,

thanks for your replay , i want to test this
:GstInterpipe - RidgeRun Developer Connection

the pipeline for creating the camera : gst-client pipeline_delete camera
gst-client pipeline_create camera
nvarguscamerasrc ! video/x-raw(memory:NVMM),width=1920,height=1080,format=I420,framerate=30/1 !
nvvidconv ! video/x-raw !
interpipesink name=camera sync=false

And for playing is :gst-client pipeline_play camera

Hi

nvarguscamerasrc only support NV12 on Jetpack 4.3. You can try using that format.

Thanks
