But when running ffmpeg transcoding using Nvenc API, I got error which says “The minimum required Nvidia driver for nvenc is 390.25 or newer”

Any suggestion ?
Thanks you.

Try installing the latest driver for your GPUs.

410.48 is not the latest.

I have managed to install NVIDIA Driver 415.13 which is the latest I found in ubuntu ppa graphic drivers (https://launchpad.net/~graphics-drivers/+archive/ubuntu/ppa). Is this the latest ? I still get same error on this 415.13 version. So strange because it said that the minimum required Nvidia driver for nvenc is just 390.25.

Problem solved: recompile ffmpeg using older version.
Worked with ffmpeg 3.4, NVIDIA Driver 415.13.

Thx. With 3.4.5 it is working.

Older ffmpeg doesn’t use nvENC API version 8.2, that’s why it works. I have the same issue with ffmpeg 4.1, latest nv-codec-headers and Linux driver 410.73. If I compile ffmpeg with nv-codec-headers from sdk/8.1 head, of course it works.

Any hint?

Discussion of same issue takes place here: https://devtalk.nvidia.com/default/topic/1038940/video-codec-sdk/announcement-new-bug-fix-version-for-video-codec-sdk-8-2/ in the video codec sdk subforum, which is more appropriate for this issue.
