Ubuntu: I introduced Kazam Screencaster back in 2007 when it was normal to question if screencasting was possible in Linux. Today Kazam Screencaster is a complete modern application for the Ubuntu Desktop with a sleek design.
Kazam screen recording application can capture the content of your screen and record a video file that can be played by any video player that supports VP8/WebM video format, be it Miro or VLC or whatever. Kazam supports H264/MP4, it is also capable of recording sound from any sound input device that is supported and visible to PulseAudio.
Latest versions of Kazam now include support for keyboard shortcuts:
start recording -> Super + Control + r
pause recording -> Super + Control + p
finish recording -> Super + Control + f
show Kazam -> Super + Control + s
quit -> Super + Control + q
Install Kazam in ubuntu
Open the terminal and run the following commands;
sudo add-apt-repository ppa:kazam-team/stable-series
sudo apt-get update
sudo apt-get install kazam
Oother Linux distributions can download Kazam Screencaster via Launchpad.
