Hello,

I'm testing the ddagrab filter with the example from the documentation. I did only add -t 10 -y, but that can't be the problem.

ffmpeg -f lavfi -i ddagrab -c:v h264_nvenc -cq 18 -t 10 -y out.mp4

What does this error message mean?
[h264_nvenc @ 000001f5f7bbf980] OpenEncodeSessionEx failed: no encode device (1): (no details)

Works here. Could be a driver issue - try reverting.

It did not work woth the older driver either. That's why I updated the driver today.
