Transcoding with NVidia driver

[pringleprng]

Transcoding seems to not be working anymore. Most likely an issue with qnap gpu driver?

515.48.07 Driver Version: 515.48.07 CUDA Version: 11.7
[hevc_nvenc @ 0x555556525380] Driver does not support the required nvenc API version. Required: 12.0 Found: 11.1
[hevc_nvenc @ 0x555556525380] The minimum required Nvidia driver for nvenc is 520.56.06 or newer

Hi,
Indeed, the last jellyfin ffmpeg requires Nvidia drivers being at least "520".
https://github.com/jellyfin/jellyfin-ffmpeg/releases/tag/v6.0.1-6

From what I seen here, the last version for QNAP is 515.
I guess you shall stick with the jellyfin 10.8.x releases until your driver being released.

Try downgrading ffmpeg to the previous version.

Can you try latest release 10.9.4 embedding ffmpeg5 if its working properly

Both the new releases for 10.9.4 regular and ffmpeg5 just do not work. 10.9.3 works fine but no transcoding of course. I'm running a TS-h686 quts hero with newest firmware. 10.9.6 doesn't work either.

can you try to look if there is the folder /opt/NVIDIA_GPU_DRV/usr/nvidia exists in your NAS.

I have added only /opt/NVIDIA_GPU_DRV/usr/nvidia to additional paths, on https://github.com/pdulvp/jellyfin-qnap/blob/master/jellyfin-ffmpeg.sh#L61C22-L61C52 but maybe the folder is not good.
maybe /opt/NVIDIA_GPU_DRV/usr/lib ?

You can try by editing the jellyfin-ffmpeg/ffmpeg file script to add paths. (and jellyfin/bin/jellyfin file script) located at /share/xxxx/.qpkg/jellyfin

Note that newer Nvidia driver has been released last week for Qnap.
Shall worth a try with the latest release of jellyfin.
