    Those are usually defaulted to the Jellyfin root directory correct? If so, they're both on an SSD

    I'm out of ideas then. I was thinking maybe there was some sort of situation where your HDD wasn't able to keep up with the IO, causing the CPU usage to spike (this happens a lot of users running JF on a RPi).

    Beginning to wonder if it's the file themselves or the server starved for resources. Tried a few A/B tests with 10.9.11 and 10.10.1 and both played fine with no buffering but I:
    1) killed docker containers I installed in the last week and
    2) tried different media files than my original post

    Tests:
    10.9.11 | Firefox (131.0.3): https://pastebin.com/5w0zM6kD
    10.9.11 | Chrome (130.0.6723.92): https://pastebin.com/fjiMxnV1

    10.10.1 | Firefox: https://pastebin.com/PffQLTaZ
    10.10.1 | Chrome: https://pastebin.com/5n1vUEV6

    Original files that were buffering: https://pastebin.com/9iXA9TpM

    I'm still at a loss for words on this. For now it seems using the Jellyfin app is the way forward on a computer since it direct plays from there (whereas browsers are transcoding and causing lags all of a sudden)

    I just installed Jellyfin on my DS1621+ (same CPU as OP, Ryzen 1500B) and wondering if there is any support in this CPU for HW accel. Should I leave it at "None" or can I enable one of the modes? I read https://jellyfin.org/docs/general/admini...-selection but stil unclear.

    I can't find documentation regarding whether the V embedded CPUs have encoders. If it does have an encoder, you'd use VAAPI. As for the codec support, probably VCN 1.0 level codec support.

    MPEG2
    VC1
    H264
    HEVC
    HEVC 10-bit (MAYBE)
    VP9

    Are you still seeing issues? I haven't tried 10.10.2 yet but something is definitely wonky in the audio transcoding with ffmpeg7 in my experience
