 I'm testing the ddagrab filter with this command line:

 ffmpeg -f lavfi -i ddagrab -c:v h264_nvenc -cq 18 -v 40 -t 10 -y out.mp4

 FFmpeg exits with this error message:
 OpenEncodeSessionEx failed: no encode device (1): (no details)

 My notebook has Nvidia Geforce RTX 2060 with the latest studio driver,
 updated today. Windows 10 Home, Version 22H2, OS build 19045.2604. DirectX
 version 12.

 This command works without problems:
 ffmpeg -f gdigrab -i desktop -c:v h264_nvenc -t 10 -y out.mp4

 This is the console output with error message at the end:
