Jellyfin transcoding on Synology NAS

[voidtrance]

Hi,

I have a DS-920+, which should support transcoding according to the documentation that I've found. I am running Jellyfin using a docker container and I have plumbed /dev/dri from the host to the container. How can I verify that Jellyfin has access to the GPU and is using it to transcode?

I tried using the method described in the docs by installing and using intel_gpu_top in the container but that return the error Failed to initialize PMU! (Invalid argument).

Thank you.

Enable HWA, then play a stream that will transcode.

If it plays, it's working fine. If not, the stream will fail to start.

How would I know if the file would transcode?

You can force a transcode by lowering the bitrate low enough to where its lower than the video's actual bitrate.
