Here is my system configuration
Driver Version : 418.87
CUDA Version : 10.1
FFMPEG Version : 4.2
I have been using FFMPEG 3.3 with CUDA 8 under Ubuntu for a couple of years now.
I recently created a new build using Source of 4.2 with CUDA 10.1.
When encoding Video using h264_nvenc I get the error “No NVENC capable devices found”
However I am able to encode using hevc_nvenc just fine.
