No GPU transcoding - Ubuntu Server, NVidia P400

[Woelfchen]

I have an older HP Desktop, installed Ubuntu Server and Jellyfin. I added a NVidia P400 GPU.

Inside the setting I enabled HW transcoding, but h265 is very slow, staggering and I dont see any process using the GPU.

Any ideas? Advices to troubleshoot?

I did everything according to the install instructions.

Otherwise jellyfin is working great!

Which instructions did you follow? Just for installing Jellyfin? If so, there are additional steps you need to take to setup Nvidia drivers and allowing jellyfin to use the graphics card. See the documentation here.

Yes, did that too

Is Ubuntu installed bare metal or Proxmox/some other VM?

Code:

sudo apt list --installed | grep -i nvidia

Verify that the encode/decode libraries installed. Not just the drivers.

Can you upload your ffmpeg log to sourcebin and link it back here? And a screenshot of your transcode settings in Jellyfin and the media info the one of the videos.

Where are the ffmpeg logs located? I'm not a linux expert ;-)
