Install NVENC 12.x with libnvidia-compute-server-525

I hope this is the right place for this. I’m rather a naive user.

Description

After successfully building HandBrakeCLI from source, it says

[12:08:57] nvenc: version 12.0 is available

I have a [NVIDIA GeForce GTX 1060 3GB].
If I’m reading this right, I’m getting my nvenc from libnvidia-encode-525-server which is coming as part of the compute library I have installed for the benefit of Folding@Home. For some reason it does not include nvenc 12.0 or 12.1.

Is it possible or safe to install the latest, greatest nvenc “on top of” or “alongside” the 525-server for the benefit of HandBrake and ffMPEG?

How would I do that? Is there a reliable APT Repository that would have it? Some other way?

Steps to reproduce the problem:

Build HandBrakeCLI from sources, then

HandBrakeCLI --version
[12:08:57] Compile-time hardening features are enabled
[12:08:57] nvenc: version 12.0 is available
[12:08:57] nvdec: is not compiled into this build
[12:08:57] CUDA Version: 6.1
[12:08:57] hb_init: starting libhb thread
[12:08:57] thread 7fd655fff640 started ("libhb")
HandBrake 1.7.1

HandBrake has exited.

HandBrake version: 1.7.1
Operating system and version: Ubuntu Linux 22.04

I think it has to do with the NVIDIA libraries on the machine.

apt list --installed libnvidia*

There’s nothing you need to install. the message

nvenc: version 12.0 is available

just means it’s already functional.

Thank you so much – I missed that; I thought it was complaining about my being behind the curve. Which is true, but…

OK, one step at a time.

Apparently I need version 12.1 but I have 12.0

I don’t quite know what this means but I guess the latest NVIDIA Driver in the “official” Ubuntu repository is a point-release behind with respect to building the very latest HandBrake.

I could PROBABLY build an earlier version of HandBrake (from sources) but that seems a little silly if I’m going to all this trouble. Or I could install the latest NVIDIA driver and hope it doesn’t break Folding@Home. But that’s a volunteer thing, so I’d just let them know…

Have I got this right?
What’s the best way to install the NVIDIA 525 driver that HandBrake/ffmpeg need?

I guess the Handbrake version you’re running needs an nvidia driver 535 or higher, please upgrade.
