Hi. I wanted to make a screencast about GuixSD, but recordmydesktop couldn't record sound.

I've found that ffmpeg is a great solution for screencast recording.

https://trac.ffmpeg.org/wiki/Capture/Desktop

ffmpeg -video_size 1024x768 -framerate 25 -f x11grab -i :0.0+100,200 -f pulse -ac 2 -i default -y output.mkv
