Will askubuntu implement uploading of screencasts ? I think screencasts are better way to show the errors or problems users might encounter.

This has been talked about before. There was some note about a screen capture to animated gif utility. It's on main somewhere.– RobotHumansCommented Sep 23, 2013 at 15:13

Sorry I didn't find about screencast on meta so I asked this question.– M.TarunCommented Sep 23, 2013 at 15:38

@M the downvote wasn't me, but that is how you get screencasts in to stackexchange.– RobotHumansCommented Sep 23, 2013 at 15:39

Ok I got it. Should I delete this question?– M.TarunCommented Sep 23, 2013 at 15:41

Downvotes don't mean the same on meta as they do on main. I'ld just leave it as is, or post a self answer about how you found out you can already do this with animated gifs and accept it.– RobotHumansCommented Sep 23, 2013 at 15:44

@M.Tarun, I think this question should be deleted, because it's basically a duplicate of that "How to create screencast" question. At first, the question seemed to me about "integrating AskUbuntu with screencasts" somehow, as like, a "button" to capture a screencast. But the whole point of your question was to just take a screencast. So this question is like stranded in the middle, it's about AskUbuntu itself, but then the answer makes this question not belong here on meta =). It can either be moved to the main AskUbuntu site and marked as a duplicate, or just deleted. I hope you understand.– Alaa AliCommented Sep 29, 2013 at 18:33

First install this:
sudo apt-get install imagemagick mplayer gtk-recordmydesktop
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:
mplayer -ao null <video file name> -vo jpeg:outdir=output
Use ImageMagick to convert the screenshots into an animated gifs.
convert output/* output.gif
you can optimize the screenshots this way:
convert output.gif -fuzz 10% -layers Optimize optimised.gif
