    Hey there,

    using jellyfin via browser (chrome, firefox, edge..), regardless of the platform (xbox, windows, linux) never works consistently, there's some media which causing more and more buffering the longer I watch, until it eventually ends up in a permanent buffering loop. Same goes for the deprecated app on XBOX or my samsung TV.

    The only consistent way to never run into playback issues is the android app on phone/tablet/fireTV.

    I made sure it's not related to connectivity (local, wired network) or weak hardware (always monitoring htop).

    Here's the metadata of 2 sample files having this issue:

    What are your server specs? When this issue occurs, is it transcoding?

    Can you share the full jellyfin server log via pastebin? If there is a ffmpeg log share that too.

    It's a lenovo thinkcentre m600 featuring an intel n3010 running ubuntu 20.04 and vaapi for transcoding.
    When I set it up I could run 4 clients transcoding 1080p60 at 20mbit down to 720p each before running into any bottlenecks.

    But it happens regardless of wether I try to stream directly or transcode to even the lowest setting, htop also doesn't show any activity, it's as if the server is just waiting for the client.

    Oof. That 3-4w CPU was underpowered when it was new. When it is just audio transcoding, it is making that conversion at about 60-70FPS. Perfectly fine if it was the only stream happening. You could probably get away with 2 audio only transcodes.

    The problem is when you are video transcoding. It looks like it is video transcoding due to the PGS subs needing to be burned in. That transcode is happening at 16-20FPS for a 24FPS video. As you can imagine, transcoding at less than real-time is not good. The output for both of these video transcodes was 1080P.

    720P for transcodes is pretty much a necessity for your setup.

    Any quality transcode has that issue, even 360p at 400kbps.

    And why does it work flawlessly the moment I switch from any browser to native app on Android and Windows?
