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?
Older ffmpeg builds.
FFmpeg build from December 15th has the same problem, but one more error
message at the end:
