unreasonably high CPU usage without throttling

[Mark Muizer]

I had a very high cpu usage due to jellyfin/docker
Host:
Linux Mint
AMD R4800H
NVIDIA GF RTX2060
image: jellyfin/jellyfin:latest

Problem:
Consistent 80% on all 16 (8x2) processors..
It starts when starting to play a film and goes on when I pause it.
-> enormous fan activity

Fix:
Under playback > transcoding:
Explicitly switching to nvidia did nothing (edit: doesn't seem to work dockerised). However, enabling throttling changed cpu usage to a steady negligable

Your issue is not really an issue.

What's most likely happening is your server needs to transcode a video for a client, but it's using the CPU cores to do so. And a transcode will continue even if you pause the video. It will only stop if the whole video is transcoded, or if you quit out of the stream.

Enabling transcode throttling just means the transcode will progress, then pause until the client catches up and needs more video.

You need to properly set up the GPU so that it handles that workload for you.
