No Hardware Transcode with Nvidia GPU.

[adamzvolanek]

Having set the docker parameters for the --runtime-nvidia, nvidia GPU's ID, and parameters, I am unable to transcode using the GTX 1660. The logs are citing a "no device available for decoder".

Expected Behavior

The ffmpeg to show transcoding behavior. Activity listed in the nvidia-smi however it is empty.

Current Behavior

FFmpeg fails to find a device and nvidia-smi remains empty from activity.

Steps to Reproduce

1. Setup JellyFin docker per instructions
2. Select 4k HEVC SDR or 4K HEVC HDR video to transcode
3. View ffmpeg logs and observe error.

Environment

• OS: Linux/Unraid
• Virtualization: Docker
• Clients: Browser, Android, iOS
• Browser: Firefox 72, Chrome OS
• Jellyfin Version: 10.7
• Playback: Transcode
• Installed Plugins: none.
• Reverse Proxy: nginx
• Base URL: local for now.
• Networking: Bridge
• Storage: Unraid NFS

Command used to create docker container (run/create/compose/screenshot)

root@localhost:# /usr/local/emhttp/plugins/dynamix.docker.manager/scripts/docker run -d --name='jellyfin' --net='bridge' -e TZ="America/Chicago" -e HOST_OS="Unraid" -e 'NVIDIA_VISIBLE_DEVICES'='GPU-201c0321-0f64-c185-4e78-ded96ed40231' -e 'PUID'='99' -e 'PGID'='100' -p '8096:8096/tcp' -p '8920:8920/tcp' -p '1900:1900/udp' -v '/mnt/user/Entertainment/Movies/':'/movies':'rw' -v '/mnt/user/Entertainment/TV Shows/':'/tv':'rw' -v '/mnt/user/Entertainment/Music/':'/music':'rw' -v '/mnt/user/appdata/jellyfin':'/config':'rw' --runtime=nvidia

container is missing libs.... run in container

apt-get install libnvidia-encode-460-server libnvidia-decode-460-server

and all works...

Apologies for not closing this previously. Another reboot (count 2) after installing the nvidia drivers plugin for Unraid, has this bug solved.
