    Hi, thanks for taking the taking the time to help me.

    Also, I know a lot of people are using JellyFin in a container. My package is deployed as a regular QPKG install.

    Have a good weekend!

    The transcode log is from 3 days ago. Before we started working on this.

    Can you share a more recent transcode log? Also, in that log I saw it was burning in subtitles. Regardless if you have hardware acceleration properly setup, subtitle burn in happens on the CPU. Which likely explains the CPU usage you are seeing. Even with hardware acceleration.

    Sorry for that.

    Since I'm on LAN for this test, it is likely that the file will play nativaly direct.

    I have put the stream limit at 5 in the streaming section (Internet streaming bitrate limit (Mbps) to force a transcoding.

    Made another test with a file without subtitles.

    I hate to ask something so simple. You scrolled down and clicked save after selecting NVENC, right?

    Code:
    Stream #0:0 -> #0:0 (hevc (native) -> h264 (libx264))

    It is still software encoding. If you've selected NVENC it would either hardware encode if everything is setup right or fail to start playback altogether. It won't fall back to software encoding.

    It is still software encoding.  Still yes.

    Can it be related to another conflicting configuration on the QNAP?

    Thanks!

    Her is my setup again.

    Nothing about this makes sense, but there are several things that are non-standard that could be causing this.

    Your use of a custom FFMPEG (not sure if this was something you did or QNAP), the QNAP "app" doesn't appear to appear to behave the same as official releases. AFAICT, the QNAP "app" version of Jellyfin just isn't passing any NVENC options to ffmpeg.

    Is Docker an option on your QNAP NAS?

    Hi there, after a few trials & errors, the QPKG that I was using seemed to be the problem. There was no custom ffmpeg included, only an old 5.x basic version. I had to update to the newest official 7.x QNAP version which was still not (again) a custom ffmpeg for Jellyfin. It worked well & Jellyfin was running it fine, but no hardware transcoding.

    For reference, the QPKG package that I have been using for a while:
    https://www.myqnap.org/?s=jellyfin.
    Stable and smaller in size. As long as you do not need to transcode, which was my case until recently, It works well.

    If you need transcoding, this is the one to get:
    https://github.com/pdulvp/jellyfin-qnap
    This one includes up to date custom FFmpeg for Jellyfin and works right away.
    So I recommend this one overall, since it works fine and is it more up to date.

    Hope this helps someone.

    @TheDreadPirate, thanks a lot for you quick responses.

    Regards, Eric
