I’ve been trying to run the examples in the NVIDIA FFmpeg Transcoding Guide.
I’m running Ubuntu 18.04 on a Dell G7 laptop with a GEFORCE 1060 card.
What I’ve tried:
ffmpeg -vsync 0 -hwaccel cuvid -c:v h264_cuvid -i input.MOV -c:a copy -c:v h264_nvenc -b:v 5M output.mkv
Resut:

I installed the NVIDIA drivers through
sudo apt install nvidia-prime
EDIT: Updated to the latest version of NVIDIA drivers available through the apt system.
As it says in the error message,
The minimum required Nvidia driver for nvenc is 435.21 or newer
, whereas I have 430.64 installed.
I found this thread, in which the issue was resolved by downgrading FFMPEG.
Which version of FFMPEG should I downgrade to, so as to resolve this issue? Or is there a better way?
How do I upgrade nvenc version to 9.1? Thanks in advance.
