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

Log:

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.

I hate to ask something so simple.  You scrolled down and clicked save after selecting NVENC, right? Yes ;-). It could have been that... 

Code:

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

It is still software encoding.  Still yes.

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.

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

Thanks!

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, just want to shime to say that I'm making some tests in the next few days.

I will come back to report here.

Thanks and happy Holidays!
