not sure about modern debian, but I digged up those two lines from year
2017:

ffmpeg -s 1280x1024 -r 30 -f x11grab -i :0.0 -f alsa -i hw:1,1 -vcodec
libx264 -crf 0 -preset ultrafast /dev/shm/output.mkv

ffmpeg -f x11grab -s 1280x1024 -r 30 -i :0.0 -f alsa -i hw:1,1 -acodec
pcm_s16le -vcodec msmpeg4 -qscale 4 -threads 4 /dev/shm/msmpeg4-2.mkv

but this was using alsa-loopback because for some reason my previous mb
integrated audio has no hw loopback mode ?!)
