Bad 4K Performance on Jellyfin - eviltoast

Hi all, looking for some help with the Jellyfin Media Player.

For background, I’ve used Plex for years, and I’ve had it working well. I’m trying out Jellyfin because of all of the reasons you’re already thinking of.

One issue I’m having - I like uncompressed 4K HDR. I’m trying to play a large movie, one Plex direct plays perfectly fine to my HTPC. (2.5GB networking through and through, direct access, all the basics have checked). However Jellyfin Media Player seems to stutter and drop frames.

Not like “It stops and buffers”, but more like playing a video game and it drops down to 15fps. Is there a setting somewhere I’m missing to enable GPU support or something? I toggled OpenGL on and off and it didn’t seem to have an effect.

Video says it’s direct play, no transcode. Not sure what else it could be beyond hardware acceleration?

Thanks!

    WDYM by “these”? I’m specifically talking about uncompressed (raw) video.

    If configured, jellyfin will transcode videos for compatibility with the playback device.

        A 90min raw 4K movie is well over 4TB in size and does not stream fine over 500Mb/s. Your 80GB “RAW” 4K movie is compressed lossily.

            Infiltrate a movie studio I guess?

            On a more serious note: There are some theoretical use-cases for this in a home lab setting if you “enhance” your video in some way server-side and want to send it to a client without loss.

            What I had actually intended with the original question is to figure out what OP was actually doing.

              What he means with uncompressed is remux, but maybe it’s only me who understands that. Because raw 4k movies is not a thing for most people.
