Description Cor Blom 2020-07-07 20:57:29 UTC 
When I install the nvidia driver from https://download.nvidia.com/opensuse/leap/15.2/ ffmpeg with nvenc does not work as normal user. It does work under root.

When I install the driver directly (the so-called hard way) ffmpeg with nvenc *does* work under a normal user account.

I see this when executing a command like:

ffmpeg -i input.mp4 -c:v h264_nvenc out.mp4

Just saw bug #1173733. Seems to be the same.

Indeed this looks like a duplicate.
