I am experiencing judder/stutter in Jellyfin but not in MPV using the exact same config file. Same problem after lots of troubleshooting and reinstalling Windows. I have been fighting this issue for months and difference is extremely palpable. I am not using any transcoding.
It's as if JF is applying some other MPV settings that I have not specified.
Config settings I have tried I have tried individually and in various combination:

Update: I am experiencing serious judder with every single file I play in Jellyfin. In MPV standalone, everything is smooth.
Here's a file I've tested with:
Here's another one that had some lag and judder, although I didn't use it to test as much:

- d3d11-flip=no definitely increases the amount of judder. But some videos will not start properly without it. In standalone MPV I will either see a white screen or just hear audio. For now I am disabling it because most videos work fine without it. But it may offer a hint as to what is causing my issue.
- I deployed a 5gb ethernet adapter to my HTPC. I am now getting almost 300MB/s on this machine from my server, so that's probably not an issue.
- The HTPC is a AMD Ryzen 7 3750H 4-core with 16 GB RAM. Not breaking 15% CPU playing huge files.
- The server is a 24-core Threadripper with like 13% of its resources in use. I am running the JF docker on unRAID.
Config settings I have tried I have tried individually and in various combination:
- video-sync=display-resample
- interpolation=yes
- tscale=oversample
- vo=gpu-next,gpu-hq (and others)
- gpu-api=d3d11
- hwdec=auto,safe-auto,no,d3d11va,d3d11
