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)
The console output is below.
My notebook has Nvidia Geforce RTX 2060 with the latest studio driver,
updated today.
This command works without problems:
ffmpeg -f gdigrab -i desktop -c:v h264_nvenc -t 10 -y out.mp4
