How can I optimize my jellyfin, specifically transcoding and the CPU usage involved? I'm running it off a mini pc so resources are everything (sh.itjust.works)

This is something that has been increasingly prevalent with my server, for the longest time I could torrent, have two people watching and everything's fine, but lately, especially with specific shows, it will take upwards of a minute for a show to start.

I've looked into it and the culprit is ffmpeg most of the time, I assume this has something to do with the specific files not having transcoding "baked in" but I don't know enough to know if that's the case. Can anyone help me optimize my pipeline at all?

Are you streaming to a Chromecast, by any chance? Or a older Galaxy device?
The 4k Chromecast with Google TV does not support AV1, but the 1080p version does. Jellyfin tried Direct Playing AV1 files, which obviously went poorly.

I run the same CPU in my NUC as you do, and all data is on a NAS shared with NFS. It's been absolutely bulletproof for about a year, so I'm confident you should be able to make this work.

Any other containers running at the same time?
No cooling issues?

Just asking because mine dropped massively in temp when repasted.
