I had to reinstall Kubuntu on this machine. I didn't have a <br>
problem until I tried to use Handbrake. It will no longer use
nvenc. <br>
I tried it using ffmpeg using the command line. First I tred
ffmpeg -i <br>
input.mp4 -vcodec h264 output.mp4. That worked, but failed
when I <br>
tried ffmpeg -i input.mp4 -vcodec h264_nvenc output.mp4 and
displayed <br>
the error message below. Before I had to reinstall, I was able
to use <br>
nvenc when encoding using h264 in Handbrake. Any idea how I
can fix <br>
this? Thanks<br>
