Screencasts and Desktop Recording

Several utilities allow you to capture your desktop (and then create a screencast from it).

recordMyDesktop (Desktop Session Recording)

recordMyDesktop is a desktop recording utility, which has both pyGTK and a pyQT4 GUI frontends available. Recordings are saved in Theora video/Vorbis audio files. Only the Gtk version is available from the repositories (but it works well with KDE/Kubuntu nevertheless). To install with the gtk GUI:

sudo apt-get install gtk-recordmydesktop

Using recordMyDesktop with PulseAudio

• If you have not installed Pulse Audio Controls and Volume utility, they are useful for monitoring your pulse audio devices:

sudo apt-get install pavucontrol paprefs padevchooser

• Change the recordMyDesktop settings so that the capture device is the one you select through pulse audio:

gtk-recordMyDesktop -> Sound Quality (ticked) -> Advanced -> Sound -> Device: pulse

This sets recordMyDesktop to use whichever input device(s) are selected through pulse audio. If you have several input devices, all of them will be recorded. This is an easy way to mix inputs.

Istanbul (Desktop Session Recording)

Istanbul is a desktop recorder for the Gnome desktop. It records your session into an OGG Theora video file.

sudo apt-get install istanbul

xvidcap is a utility to capture your desktop as a video. Install:

sudo apt-get install xvidcap
