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.
1) Try older builds, say, a month or two older.
Do you mean older builds of FFmpeg, or older Nvidia driver?
2) Paste full log of working gdigrab command.
