Docker: ffdetect_nvencdec Process exited with code 1

[3n8 7]

I've been running Emby with GPU transcoding for multiple years now but if i try to update past version 4.7.6.0 (Linuxserver docker) the container won't even finish the configuration but i can't come here and ask for help with someone elses container so i've been trying to resolve my issues with the official Emby/Embyserver container and i'm hoping for some help

The container start fine but nvidia-smi is not found in the shell and the logs are showing:
ffdetect_nvencdec Process exited with code 1
nCannot load libcuda.so.1\nError loading CUDA functions\n\n","Result":{
Configuration": "--cc=x86_64-emby-linux-gnu-gcc ......
    },
    "Error": {
        "Number": -1,
        "Message": "Operation not permitted"
    },
    "Log": [
        {
            "Level": 16,
            "Category": 0,
            "Message": "Cannot load libcuda.so.1"
        },
        {
            "Level": 16,
            "Category": 0,
            "Message": "Error loading CUDA functions"

And clicking advanced under hardware acceleration gives no options

Host is Arch Linux 6.1.3-arch1-1, I've been trying to see if this works every few months so it has been tried with older kernels through those months.
Emby premiere is enabled
Gpu is a quadro p620p
NVIDIA-SMI 525.78.01
Driver Version: 525.78.01
CUDA Version: 12.0
docker 1:20.10.22-1 (latest)
libnvidia-container 1.5.1-1
libnvidia-container-tools 1.5.1-1
nvidia-container-runtime 3.5.0-2
nvidia-container-toolkit 1.5.1-1

I've previously used the official Emby container without issues but i have never before tried it with hardware encoding
For the purpose of finding the issue i've been testing on a fresh install of the official Emby/Embyserver container from hub.docker with premium enabled
I've tried other media servers to see if hardware encoding works there and it does
I've tried to go backwards with the official Emby docker container but can't seem to find an older version that work with hardware acceleration
I've tried to roll back my drivers to an older version with no luck
nvidia-smi is not found when run from the containers shell

I've seen an issue or two here that resemble mine but they either don't come to a conclusion, Have a different cuda errror or and have not attempted running other containers that requre GPU acceleration, Which works flawlessly for me

docker-compose:

  embytest:
    image: emby/embyserver:latest
    hostname: embytest.docker
    container_name: embytest
    restart: always
    networks:
      - frontend
#    ports:
#      - 9096:9096
#      - 9920:9920
    mem_limit: 4g
    runtime: nvidia
    devices:
      - /dev/dri:/dev/dri
    deploy:
      resources:
        reservations:
          devices:
            - capabilities: [gpu]
    environment:
      - UID=${PUID}
      - GID=${PGID}
      - GIDLIST=985,989
      - NVIDIA_VISIBLE_DEVICES=all
    volumes:
      - ${DOCKER_HOME}/embytest:/config
      - media:/mnt/media
    dns:
      - 1.1.1.1
      - 1.0.0.1

How i configured my host to enable the nvidia-container-runtime

Blacklisted nouveau
added the kernel parameter (systemd.unified_cgroup_hierarchy=false)
edited /etc/nvidia-container-runtime/config.toml (no-cgroups = false)
rebuild the boot image
added: /etc/docker/daemon.json with:
rebooted
{
  "runtimes": {
    "nvidia": {
      "path": "/usr/bin/nvidia-container-runtime",
      "runtimeArgs": []
    }
  }
}

installed the latest good nvidia driver that works with the nvidia patch
patched nvidia
rebooted

gpu acceleration with the linuxserver docker would not work without this added to docker-compose:
    deploy:
      resources:
        reservations:
          devices:
            - capabilities: [gpu]

Hi, have you taken a look at this?

 

[3n8 7]

There was nothing in that post that i'm not aware off.
And like i've written: I don't have an issue with GPU acceleration, nor configuring Emby, I've been using dockers and gpu acceleration for years.
I have an issue with Emby server, Everything else works, I've tried other mediaservers, They work.

It is only emby that is not working
I'm testing with the official Emby/Embyserver container now but it is not working,
but it will work with the linuxserver emby container up to and including emby 4.7.0
