First install this:
<code bash>
sudo apt-get install imagemagick mplayer gtk-recordmydesktop
</code>
those are the required stuff, ImageMagick, MPlayer and Desktop Recorder. Then use Desktop Recorder to capture a portion of the screen/application to use as the screencast. After the Desktop Recorder has saved the recording into an OGV video, MPlayer will be used to capture JPEG screenshots, saving them into the 'output' directory.\\
\\
On a terminal:
<code bash>
mplayer -ao null <video file name> -vo jpeg:outdir=output
</code>
Use ImageMagick to convert the screenshots into an animated gifs.
<code bash>
convert output/* output.gif
</code>
you can optimize the screenshots this way:
<code bash>
convert output.gif -fuzz 10% -layers Optimize optimised.gif
