Screen Capture with FFMpeg with Audio

Found it useful to capture the Linux desktop using FFMpeg, most useful with audio. Accomplished it using the following command:

$ ffmpeg -y -f alsa -i pulse -f x11grab -r 25 -s 1366x768 -i :0.0 -qscale 1 -s 1024x768  screenCap.mpg
First dimension specified is the resolution of the desktop, the second dimension is the desired resized video dimension. Cheers.
