HEVC playback high GPU usage - Madwish - 2023-09-29
it is not exactly a Jellyfin problem, but maybe there is some setting in it that could help me.
So i play games and watch movies\shows in the background, sometimes sonarr or radarr downloads me a HEVC one. It causes low fps in both game and video.
I measured a bit and i think i get like 10-30% usage from video alone. I find it a bit ridiculous since i got a 3080 TI. Is it normal? Can i reduce it\downgrade somehow without using hardware acceleration (my server uses xeon e5-2650 and 9600 gt, pretty sure it can't hardware accelerate, which is strange since it plays same video just fine) or downloading h264 files?

I would say this is not a Jellyfin question. The problem is upstream (with your Servarr setup). The golden rule is to match your media to your clients, and it sounds as though your client can't handle HEVC. You will need to figure out how to avoid HEVC media in your collection, but hardware acceleration is functioning properly and there's not a way to throttle transcoding in the way you've requested. You can check out the Throttle Transcodes setting, but all that will do is pause transcoding once enough has been transcoded to play a section of the media, it will not reduce the GPU usage.
Your direction needs to be Sonarr and Radarr. I would start with *figuring out how to avoid HEVC. The other option is a different client that supports HEVC, which could be simple as well.

HEVC is more computationally expensive than h264, yes. I'm not sure how much of the resources of your 3080ti it should use to decode HEVC video though. Putting a more capable GPU in the server and enabling hardware acceleration might give you more flexibility.
We can't really support sonarr and radarr here. So you'd have to reach out to their support communities to ask if there is something that can be done to avoid HEVC content.

Okay, thank you, guessed as much
