Screen cast on linux with ffmpeg

Few days ago I was happy to found the link with 10 useful Linux commands at

The last one command was the most interesting for me, as it helps to make screen casts quickly and easy with only one command:

ffmpeg -f x11grab -s wxga -r 25 -i :0.0 -sameq ~/out.mpg

Moreover ffmpeg helps to setup video quality, convert it to FLV format, so you can publish video online with a few clicks!
