My fix for HW encoding. Symlink for ffmpeg.

[blumoreno]

I am running the latest version at this time, running docker compose in Ubuntu with a GTX1080. I had trouble getting HW encoding working and hope my solution could be added to the official image.

When running ffmpeg -version inside the container, I got "ffmpeg: command not found", but I know it is included with the image. I found the location of ffmpeg with find / -name ffmpeg 2>/dev/null

ffmpeg was in /usr/lib/jellyfin-ffmpeg/ffmpeg but not where is should be: /usr/bin/ffmpeg My resolution was creating a symlink by running ln -s /usr/lib/jellyfin-ffmpeg/ffmpeg /usr/bin/ffmpeg

My jellyfin is now successfully transcoding, and nvidia-smi on the host shows ffmpeg in GPU utilization.

My docker compose:

  jellyfin:
    image: lscr.io/linuxserver/jellyfin:latest
    runtime: nvidia
