At the moment I am using:
ffmpeg -async 1
       -f alsa
       -ac 1
       -i hw:1,0,0
       -f x11grab -s 1920x1080
       -r 25
       -i :0.0
       -acodec libmp3lame
       -ar 22050
       -ab 64k
       -qscale:video 4

This works reasonably good. The only problem is that there is some
white noise in the audio. Is there a way to filter this away?
