How to create a screencast in Ubuntu, and why you should do it under Linux
never mind the text on my wallpaper, it's just coincidence. This is not a political talk.
Why Ubuntu/Linux is a great platform to create screencasts...
1. The tools are freely available
2. The culture of sharing is part of the OS
3. Easy to install reliable software (software center)
Some helpfull pages and tricks:
On configuring mplayer: • Video
DroidCam: Use your tablet/phone as webcam http://www.dev47apps.com/
Use this PPA under Ubuntu: http://www.webupd8.org/2014/06/instal...
To show keystrokes, install key-mon in your distro of choice.
To record your desktop, install gtkRecordMyDesktop (or just RecordMyDesktop if you like command line fu)
Extra video on recording using gtkRecordMyDesktop:

I'm sorry I didn't find a free and open source alternative to DroidCam. If you have suggestions, please share them. This would be even better if it were all free software (I'd gladly pay for this freedom)
RecordMyDesktop generates an .ogv file - this works just great for uploading to the big cloud video services out there. If you prefer to have it in your own format of choice... you could use ffmpeg or avconv to convert it. I'm pretty certain you're all smart enough to google for this program name with "convert .ogv to .mp4" :)
