Jellyfin stuttering

Hi,

I have recently set up a Jellyfin server running on a Beelink S12 pro in docker (with a few other containers running), and I am having a few problems with stuttering video.

I get little micro-stutters every few seconds regardless of whether it is direct play or transcoding and regardless of what client I use (librelec with Jellyfin plugin), android phone, or firefox on a windows laptop), and I am struggling to narrow down the cause of it.

Any ideas of where I should look first?

The server utilisation seems low, I have tried a wired and wifi connection, I have tried 720, 1080, and 2160 resolution videos, with and without transcoding.

Any help would be greatly appreciated.

Edit: I think I have now fixed the problem. I tried a new setup on my gaming PC and everything worked fine. This was running on the same network and same client. This made me think it was something with my server. I used the cup-shares docker command to prioritise the jellyfin container and I've had no stutters since.

Edit2: turns that has not fixed it 😔
