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 “uncompressed”? A truly uncompressed 4K HDR movie needs about 6Gbit/s of goodput. A 2.5Gbit/s link won’t be enough for that.

        I see. In future, better refer to this as “ripped blu-rays” or “ripped ISOs” to avoid confusion. “uncompressed” really does mean something entirely different.

        Glad you managed to sort it out :)

        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.

      Should that matter for direct play? On Plex I never used hardware acceleration and focused on my media player being able to play everything. My client is a full PC, with an Nvidia GPU on Windows. The client doesn’t seem to be using it from what I can tell.

      Am I misunderstanding this? Is a client setup here different from the server?

        In my personal experience the jellyfin clients just aren’t as good. I play my whole jellyfin library through Kodi and everything direct plays without issue.

          Don’t like the default clients either, I use Delfin on Linux and Findroid on Android

        Try jellyfin-mpv-shim. It directly uses mpv (either a built in version or even your system mpv) and if it doesn’t play well there, it’s likely not going to play well anywhere.

        What browser are you using? Is your CPU usage usually high during playback? If so your system isn’t using hardware decode

    I was having issues a few weeks ago, using the Jellyfin client on the Google TV w/ Chromecast, and a lot of them were solved by reinstalling the app.

    Likely not a server-side problem (check CPU usage on the server), if the server was struggling to transcode I think it would result in the playback pausing, and resuming when the encoder catches up. Network/bandwidth problems would result in buffering. This looks like a bad playback performance problem, what client are you using? Try with multiple clients (use the web interface ina browser as a baseline) and see if it makes any difference.
