Default how to record desktop video and audio with ffmpeg?

Code:
ffmpeg -video_size 1680x1050 -framerate 30 -f x11grab -i :0.0 -c:v libx264 -qp 0 -preset ultrafast output.mkv

I've not had good luck (on FreeBSD and CentOS with ffmpeg recording the desktop). I used simplescreendesktop in Linux and I think FreeBSD has recordmydesktop. I don't know if either are available in OpenBSD though.
https://trac.ffmpeg.org/wiki/Capture/Desktop is the ffmpeg link.

If you do have success, please post about it, I'd be curious.

The FAQ describes how to create a monitor mix with sndiod. Once I’d done so, I was able to record audio and video with a variant of your command:

Code:
ffmpeg -f sndio -i snd/0.mon -video_size 1680x1050 -framerate 30 -f x11grab -i :0.0 -c:v libx264 -qp 0 -preset ultrafast output.mkv
