As requested, I’ve posted a new topic with regards to running a CSI camera inside a container. I’m using the following container: nvcr.io/nvidia/l4t-base:r32.3.1
And runnning nvargus-daemon inside the container results in
bash: nvargus-daemon: command not found
Original problem posted here: https://devtalk.nvidia.com/default/topic/1068583/jetson-nano/jetpack-4-3-l4t-r32-3-1-released/post/5423380/#5423380

Thanks jimwormold, can you try launching Docker with these flags?
sudo docker run --net=host --runtime nvidia --rm --ipc=host -v /tmp/.X11-unix/:/tmp/.X11-unix/ -v /tmp/argus_socket:/tmp/argus_socket --cap-add SYS_PTRACE -e DISPLAY=$DISPLAY -it nvcr.io/nvidia/l4t-base:r32.2.1
Note the –ipc=host and -v /tmp/argus_socket:/tmp/argus_socket arguments.
That’s fantastic and I can confirm that this works using the above command from within a container! Thank you
However when I attempt to grab the stream from opencv, it fails. I have built opencv 4.1.2 within the container, using the https://github.com/mdegans/nano_build_opencv script which sets the option to build gstreamer to true, however when I check this with cv2.getBuildProperties() it states that it has not been built with gstreamer.
Installing the following dependencies before running the opencv build script fixes this:
apt install libgstreamer1.0-dev libgstreamer-plugins-base1.0-dev
Thanks for the report. I will try to replicate and add the second package explicitly to the build script.
Edit: looks like it isn’t added by the main -dev package. I will add it later today. Thanks!
HI,
What’s the purpose of /tmp/.X11-unix?

Inside are sockets so you can connect to the local display. You may wish to use a network sink instead of X depending on what you are doing, however. There is a python example in that thread that works. Then you can just EXPOSE a port and connect to it from outside the container (or another host altogether). You can then use gst-play (or probably even vlc) as a remote display client for your camera feed. The osd stuff works as well if you stick it in your pipeline.
Interesting.
Ok, I’ve solved authentication issues, it is basic X system administration.
Xauth set, $Display set, xrandr correct, I can launch xterm in GUI.
What is the meaning of this EGL display connection issue?
I did not manage to get X window output with nvargus.
When I unset DISPLAY I can run some some commands and bypass that error but I do not see anything.
Is openGL incompatible with X11?
Thanks for the details and help.
