Can't access nvhost-msenc inside a container

Running the following docker run command:
sudo docker run -it --net=host --device=/dev/nvhost-msenc --runtime=nvidia 428205b27ec4

With the following gstreamer command:
gst-launch-1.0 videotestsrc is-live=1 num-buffers=600 ! video/x-raw,width=320,height=240,framerate=60/1 ! nvvidconv ! ‘video/x-raw(memory:NVMM), width=(int)3840, height=(int)2160, format=(string)NV12’ ! nvv4l2h265enc ! h265parse ! qtmux ! filesink location=filename_h265.mp4 -e

I get the following error regarding nvv4l2e265enc:
ERROR: from element /GstPipeline:pipeline0/nvv4l2h265enc:nvv4l2h265enc0: Could not open device ‘/dev/nvhost-msenc’ for reading and writing.
Additional debug info:

system error: No such file or directory

Anyone have an idea of what is wrong here?

Hi,

Could you share where the command comes from?
Thanks.

Do you mean the gstreamer pipeline? I took a random pipeline command from NVIDIA forums.
This error persist on every pipeline I’m trying.

Hi,

No, we want to know the docker command comes from.

The GStreamer command works well.
We tested it within a base container, the h265 mp4 file can generate without error.
Please give it a try.

$ export DISPLAY=:0
$ xhost +
$ sudo docker run -it --rm --net=host --runtime nvidia -e DISPLAY=$DISPLAY -v /tmp/.X11-unix/:/tmp/.X11-unix nvcr.io/nvidia/l4t-base:35.3.1

Hi, thanks for your reply.

When I run xhost + I get this error:
user@user-desktop:~$ export DISPLAY=:0
user@user-desktop:~$ xhost +
Invalid MIT-MAGIC-COOKIE-1 keyxhost: unable to open display “:0”

When I run the docker and then the GStreamer command, the pipline runs however I get the following errors(Bolded):

Hi,

Do you have a display device connected to the Jetson?
If not, could you try unset DISPLAY to see if it helps?

Thanks.
