no element "nvv4l2decoder" in Docker

[poett1]

I'm trying to run the detectnet tracking example using docker on Xavier AGX (L4T 35.2.1). It seems like the nvv4l2decoder is not installed in the container.

Gstreamer is unable to find the plugin:

No such element or plugin 'nvv4l2decoder'

Any hints?

Is you run gst-inspect outside container, can nvv4l2decoder be found? These plug-ins get mounted into container by gstreamer

Outside the container everything looks good so far.

Hmm, does your /etc/nvidia-container-runtime/host-files-for-container.d/l4t.csv file look like this?

No, its different.

I'm having the same issue, @poett1 did you manage to make it work?

[poett1]

I solved it by setting /etc/docker/daemon.json to:

{
    "runtimes": {
        "nvidia": {
            "path": "/usr/bin/nvidia-container-runtime",
            "runtimeArgs": []
        }
    },
	"default-runtime": "nvidia"
}

Otherwise the Nividia libraries are not mounted into the container.
