Currently using Gstreamer’s videotestsrc can be tested and shown to be normal, but currently DeepStream is aborted.

Please provide complete information as applicable to your setup.
• Hardware Platform (Jetson / GPU)
• DeepStream Version
• JetPack Version (valid for Jetson only)
• TensorRT Version
• NVIDIA GPU Driver Version (valid for GPU only)
• Issue Type( questions, new requirements, bugs)
• How to reproduce the issue ? (This is for bugs. Including which sample app is using, the configuration files content, the command line used and other details for reproducing)
• Requirement details( This is for new requirement. Including the module name-for which plugin or for which sample application, the function description)
• The pipeline being used

junshengy · July 24, 2023, 1:32am

Are you want display video over x11-forwarding ? DeepStream don’t support it currently.
You can try sink to file or rtsp for display result.

Thanks

229616726 · July 24, 2023, 1:50am

ok, I always thought it could be displayed
How should the image be displayed in docker

junshengy · July 24, 2023, 2:02am

Start docker like below

docker run --gpus "device=0" -it --rm -v /tmp/.X11-unix:/tmp/.X11-unix -e DISPLAY=$DISPLAY -e CUDA_CACHE_DISABLE=0 nvcr.io/nvidia/deepstream:6.2-triton

When your server had monitor plugged, you can see the video.

junshengy · July 24, 2023, 3:07am

What’s the output of xrandr ? Is the value of DISPLAY correct ?

Before run docker, try run this command.

xhost +

229616726 · July 24, 2023, 3:12am

Output DISPLAY
echo $DISPLAY
localhost:10.0

I can’t call xhost +

junshengy · July 24, 2023, 6:22am

run xhost + with root is is required. otherwise it won’t work.

If you don’t have root, I recommend you to sink to file/rtsp/fakesink.

I am currently running under root

There may be some issues with sudo.
try to use root user.
or try replace DISPLAY=$DISPLAY to DISPLAY=localhost:10.0

229616726 · July 24, 2023, 8:22am

This setting is still the above error

junshengy · July 24, 2023, 8:32am

The value of the environment variable looks a bit abnormal.
This value is usually :0 or :1, Close your local x11-server

try export DISPLAY=:0 or export DISPLAY=:1 in you ssh.

ok, it has been confirmed, but when I compile my own development software, I lack cuda_runtime_api.h and other header files. How do I install this?

junshengy · July 24, 2023, 9:32am

Is there any output from nvcc --version command?

If yes, cuda is usually installed to /usr/local/cuda.

If no, deepstream app not be compile too.

you can try jetpack for install it.

If you have more questions. please open a new topic.

Thanks

I used this command today and got an error again : Could not get EGL display connection

run commond echo $DISPLAY
:0

sudo docker run -it --rm --net=host --runtime nvidia -e DISPLAY=$DISPLAY -w /opt/nvidia/deepstream/deepstream-6.2 -v /tmp/.X11-unix/:/tmp/.X11-unix nvcr.io/nvidia/deepstream-l4t:6.2-base

Use root user，don’t use sudo
or you can try DISPLAY=:0
Some environment variables do not take effect under sudo

229616726 · July 25, 2023, 10:00am

I am using the root identity
