March 29, 20251 yr Hello! I recently bought an Nvidia Quadro P400 to upgrade and enable me to use hardware transcoding. The issue I'm running into is a fatal playback error for every piece of media using the HEVC codec and nothing else. What I've tried so far after searching other forums: 1. I switched from using binhex's version to the official version (jellyfin/jellyfin repository) 2. I have added "--device=/dev/dri" to extra parameters. 3. I have downloaded GPU statistics plugin to make sure the gpu is up and running correctly (it is) Everything in the logs seems normal, except the following errors. Google search has not helped me identify what FFmpeg exit code 255 means. [07:20:00] [ERR] [25] MediaBrowser.MediaEncoding.Transcoding.TranscodeManager: FFmpeg exited with code 255 [07:20:00] [ERR] [25] Jellyfin.Api.Middleware.ExceptionMiddleware: Error processing request. URL GET /videos/8ac33a65-a9e6-b34c-7acc-4d0a9881772e/hls1/main/-1.mp4. MediaBrowser.Common.FfmpegException: FFmpeg exited with code 255 Any help would be greatly appreciated!
March 29, 20251 yr Community Expert "--device=/dev/dri" helps but is not the way... this is more for intel cards. Some nvidia need the extra access to check. per ICH777 its actual using /dev/nvidia you would need to check it and that is orginaly part of the puzzle... You will need to make sure the g card is not VFIO bound, it must be accessible to the host... You will need to install the NVIDIA plugin driver. web UI > Settings > nvidia You will see your quadro card under NVIDIA info and can run nivida-smi in teh terminal to see the card... Next to use a nvida GPU with unraid the min requirement after the host plugin and driver are working is: Docker settings: in the extra parameter filed you need to add --runtime=nvidia in the docker tempate you may need to add variable: Depending on your Jellyfin docker, as the docker needa to have the drivers in the image... You may need to read the overview or additional requirement to add the GPU... I recommend using linuxIO - linux server jellyfin template and image Latest tag then adding the NVIDIA runtime and additional docker variable... Edited March 29, 20251 yr by bmartino1 typo
