I watch Hak5 on my S2 TiVo. This season, DK is doing everything on Linux. He’s covered a fairly powerful home router already with smoothwall. The home-made commercials are usually the best parts of the show m(seriously!), but episode 804 covers the easy and slightly harder way to record your Linux desktop for screen casts.

gtk record my desktop for you GUI-liking people and ffmpeg for the shell folks like me that prefer a little more control are demonstrated.

The guys over a CommandLineFu also covered the ffmpeg way of doing it with a little more finesse. Don’t you just love that domain name?!!!

ffmpeg -f alsa -itsoffset 00:00:02.000 -ac 2 -i hw:0,0 -f x11grab -s $(xwininfo -root | grep 'geometry' | awk '{print $2;}') -r 10 -i :0.0 -sameq -f mp4 -s wvga -y intro.mp4

Hak5 isn’t the first to cover this topic. A quick search finds thousands of others demonstrating how to do this as well, but a few of the Hak5 commercials are GREAT!
