Jellyfin Linux Desktop Client Performance Slow

[TheDreadPirate]

It does use MPV under the hood, but due to reasons I can only parrot from the devs the way the library we use to render the OSD prevents HDR from rendering properly.

But you can use Jellyfin MPV Shim. It comes bundled with MPV, but you can swap it out with a newer version of MPV.

Would it be useful to try to reproduce the problem with a non-HDR file?

[TheDreadPirate]

Sure.

I tried shim, the performance is still worse than other players like kodi using the jellyfin addon but better than running in the jellyfin desktop app. Strange.

Here's the SDR, it performs roughly equivalently to the HDR.

Any additional diagnostic steps I can try to take? It's so strange to me that I have no issues with the Jellyfin addon for Kodi. Kodi must either be doing something or have access to something that Jellyfin doesn't do/have to enable it to perform so much better.

[TheDreadPirate]

Honestly not sure. Sounds like you should stick with Kodi?

Hey - I also ran into this issue on my Linux headless server running the latest Ubuntu. I fiddled with hardware acceleration, bandwidth limits, encodings, and nothing worked. What worked for me was to package my media file in an mkv container without re-encoding:

ffmpeg -y -i inputfile -c:v copy -c:a copy output.mkv
