Can't communicate with camera in Docker

I’m trying to use camera in Docker container on my Jetson Nanpo. Without Docker container everything looks ok:

  1. I can take pictures
  2. gst-launch-1.0 nvarguscamerasrc ! fakesink gives me normal output:
Setting pipeline to PAUSED ...

However if I try to communicate with camera in docker, I have this message for gst-launch-1.0 nvarguscamerasrc ! fakesink:

How can I fix this?
My docker container configuration:

  1. Base image is nvcr.io/nvidia/l4t-base:r36.2.0
  2. Running config is:
    --privileged -v /dev/shm:/dev/shm -v /var/run/avahi-daemon/socket:/var/run/avahi-daemon/socket -v /tmp/argus_socket:/tmp/argus_socket -v /data:/data --network=host --runtime nvidia -v /tmp/.X11-unix/:/tmp/.X11-unix -v /dev/:/dev/
  3. Before running gst-launch-1.0 nvarguscamerasrc ! fakesink I always export env variable: export LD_PRELOAD=${LD_PRELOAD}:/usr/lib/aarch64-linux-gnu/libGLdispatch.so

Hello @lelikk2002,

You might find this interesting:

But I don’t have display, that’s why I don’t export DISPLAY variable

If I do what was listed in your link, I get this:

duckie@duckie06:~$ export DISPLAY=:0
duckie@duckie06:~$ xhost +
No protocol specified
xhost:  unable to open display ":0"

And I don’t use deepstream

@lelikk2002,

Thanks for getting back with more details.

Got it, yeah.

Can you try adding -e DISPLAY=$DISPLAY to your Docker run flags ?

I’ve added nothing changed. The reason is that I don’t have DISPLAY variable in my shell, setting it to 0 as it was written in guide you’ve sent also didn’t bring any new results

@lelikk2002,

Thanks for running the test.

That is weird.
We do understand that you don’t have a display connected, we have a similar setup for one of our customers.
However, we are able to capture with nvarguscamerasrc.

But checking your flags, its seems like you are using the same as ours.

We will try to do more research over here.
