I can use such encoder with ffmpeg:

ffmpeg -f v4l2 -i /dev/video0 -c:v h264_nvenc out.mkv

Hi, had the same issue, but fixed by using --bframes (or -b): wf-recorder --codec h264_nvenc -b -f recording.mp4

Interesting, I do not have this issue, and I am using quite an elaborate command too.

$ wf-recorder -a easyeffects_sink -C aac -r 60 -c hevc_nvenc -p tier=high -p spatial-aq=1 -p multipass=fullres -p rc=vbr -p cq=24 -p qmin=24 -p qmax=24 -p profile:v=main10 -p preset:v=p7 -x yuv444p -F hue=h=-3:s=0.98, eq=gamma=0.98:contrast=0.99 -f ~/Videos/190424-215004.mp4

I also tried with h264 instead of hevc, same result.

I am on endeavouros, instead of nvidia-open-dkms I am on nvidia-dkms 550.67-1, so that might be the difference.

But I can see this issue is quite old, so maybe it has just been fixed by now?

To use nvenc, -r seems to be required:

wf-recorder --codec h264_nvenc -r 60 -f recording.mkv
