This is something that has been increasingly prevalent with my server, for the longest time I could torrent, have two people watching and everything’s fine, but lately, especially with specific shows, it will take upwards of a minute for a show to start.

I’ve looked into it and the culprit is ffmpeg most of the time, I assume this has something to do with the specific files not having transcoding “baked in” but I don’t know enough to know if that’s the case. Can anyone help me optimize my pipeline at all?

    If everything is working correctly, whether or not you transcode is basically whether or not the end device can play the file without changes.

    For example, my old Roku can play a raw 4K File under H264 with no problem. But if I throw an H265 at it, it requires the server to transcode. It also has problems with AAC audio. And my server is so old that just trying to rip the 4k apart entrance to the audio is often too much for it.

    So to start, make sure your client device can play the files directly. If it can’t, you’re going to need to handbrake it before you put it on your server.

    Is it Intel?

    If so I would use GPU acceleration

    Edit: I see it is a N100. Definitely use hardware acceleration. I would also make sure that you run your media though Handbrake if it is in raw form.

    why are you transcoding at all? it’s the first thing I turn off on jellyfin (and previously plex) installs. negligible cpu usage on both server and client when directplaying content.

      Is that an option? It was my understanding anime stuff typically comes with several subtitles and in my case dual audio for each episode

        not knowledgeable about them things but normal movies and shows with multiple audio streams and subtitles play just fine with directplay, selecting them from the client works fine, etc.

        the only reasons I know of for transcoding would be if you have ancient clients that can’t play e.g HEVC or something, or if you’re on shitty broadband and it ain’t feasible to stream 4K to a phone.
