Jetson Inference - Could not open DRM module (NULL) - gstreamer - 5.10.104-tegra

Hello everyone,

I am using the jetson inference repo from @dustynv (GitHub - dusty-nv/jetson-inference: Hello AI World guide to deploying deep-learning inference networks and deep vision primitives with TensorRT and NVIDIA Jetson.) with the Neousys Technology NRU-110V. To map ROS functionalities, I have flashed the system to Jetpack 5.1 according to the manufacturer’s instructions. As an example pipeline, I use the following gstreamer instructions outside the Docker container:

GST_DEBUG=3 gst-launch-1.0 v4l2src device=/dev/video0 ! video/x-raw,width=1280,height=720,format=UYVY ! autovideosink

Outside the container, the pipeline works without errors. As soon as I want to run the pipeline inside the container, I get the following error message:

*root@tegra-ubuntu:/# GST_DEBUG=3 gst-launch-1.0  v4l2src device=/dev/video0 ! video/x-raw,width=1280,height=720,format=UYVY ! autovideosink*

I have already been able to narrow down the cause field to possibly missing authorizations or unrecognized DRM drivers via other posts. My goal is ultimately to use the functionalities of the repository, but these give me similar error messages. Therefore, the basic gstreamer pipeline should run first.

Here is my info from jtop. I did not install the missing libraries due to limited memory space. The nvidia docker container toolkit is installed. If further information is required, I will be happy to provide it:

I would be grateful for any help.
Thanks a lot!

Hi,
Please follow this and share which sink is picked:
Gstream not work in AGX Orgin But ok in Xavier NX - #5 by DaneLLL

And possible reasons that display fails in docker:
"No EGL Display" error coming while running deepstream python app inside a docker - #9 by vino_mm
Unable to display images using Open CV when using docker container - #3 by AastaLLL

Hi DaneLLL,

outside docker: xvimagesink
based on the debug output > inside docker: nv3dsink

Following these steps No xvimagesink on deepstream-l4t - #12 by pvmilk
Im able to use videotestsrc and get a window. Nevertheless the window content with the real pipeline is just a black screen.

As an addition to the previous post: I start both containers with -v /lib/modules/5.10.104-tegra:/lib/modules/5.10.104-tegra to avoid getting modprobe errors. I got the info according to a comment from #1556.

Do you have further suggestions?

Thanks for your help!

I have the same problem. Video is just a black screen. Any known solutions to this?
