Comment (by Sergey Svistunov):

 I have this error on ffmpeg 6.1.1 when trying to use ddagrab to record a
 non-primary display on my laptop with hybrid graphics (Intel + NVidia).

 Seems to be fixed in ffmpeg 7.1.1.

 ffmpeg 6.1.1:
 {{{
 ffmpeg -hide_banner -init_hw_device d3d11va:0 -thread_queue_size 1024
 -rtbufsize 256M -filter_complex
 ddagrab=framerate=30:draw_mouse=0:output_idx=0,hwdownload,format=bgra
 -vcodec libx264 -b:v 3400k -r 30 -pix_fmt yuv420p -preset fast -movflags
 +faststart "test.mp4"
