How can I optimize my jellyfin, specifically transcoding and the CPU usage involved? I'm running it off a mini pc so resources are everything (sh.itjust.works)

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?

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

    I watch a bunch of weekly anime stuff myself. Never have to worry about transcoding with my devices (locally) and just directplay it. Unless I watch it remotely then it transcodes, I never mess with the default settings and it's fine.

    My cpu is i3 8100 so I think you would be fine as well, unless it's multiple streams at once I have no reference for that.

    Especially anime often use the superior .ass subtitle format, which many devices don't support. Sadly Crunchyroll is switching to .srt which has broader support, so it likely won't require burning them in the video (transcoding), which is the only positive thing (still a shame imo).

    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.
