Kazam Screencaster Gets Webcam And YouTube Live Support, On-Screen Mouse Click And Keyboard Indicator

Kazam is a GStreamer-based screen recording and screenshot tool for Linux. The application supports recording the entire screen (with multi-monitor support), a window or an area and features:

customizable framerate;
option to show/hide the mouse when recording;
record sound from speakers and/or microphone;
keyboard shortcuts;
configurable delay before capturing;
automatic file saving;
supports mp4 (H264), webm (VP8) and avi (RAW, HUFFYUV and lossless JPEG) video formats.

Kazam 1.5.3 was released recently and it includes some very useful new features:

support for webcams: it can record just the webcam or it can display the webcam in a window on top of the screencast;
support for broadcasting to YouTube Live;
added on-screen keyboard indicator and mouse click indicator;
new countdown timer.

Here are a few screenshots with some of these changes:

Install Kazam Screencaster in Ubuntu / Linux Mint

Kazam is available in the official Ubuntu repositories, but it's an old version so it doesn't have the new features mentioned in this article. To get the latest Kazam in Ubuntu or Linux Mint (and derivatives), you can use a PPA.

To add the PPA and install Kazam Screencaster, use the following commands:

sudo add-apt-repository ppa:kazam-team/unstable-series
sudo apt-get update
sudo apt-get install kazam python3-cairo python3-xlib

For other Linux distributions, grab the latest Kazam (unstable branch) from HERE (BZR).

Report any bugs you may find @ Launchpad.

Screencasting App `Simple Screen Recorder` 0.3.0 Adds Profile Support, New OpenGL Recording System And Lots More

Simple Screen Recorder (SSR), a Qt desktop recorder for Linux, was updated to version 0.3.0 today, bringing profile support, a new, more flexible OpenGL recording system, native support for mono microphones and other interesting changes.

The tool comes with basically all the features you need in a screencast app: record the entire screen (with multi-monitor support), record a fixed rectangle, follow the cursor, record OpenGL applications (which can be used to record games), record audio input (PulseAudio, JACK and ALSA), options to scale the video, to record (or not) the cursor, to pause/resume the recording and so on. It even has experimental live streaming support.

Simple Screen Recorder can record your screen using any container (MP4, MKV, OGG, WebM and so on) and audio/video codec (H.264, VP8, Theora for videos and Vorbis, mp3, AAC, etc. for audio) supported by libav, with configurable bit rate, etc.

Changes in the latest Simple Screen Recorder 0.3.0:

added profile support;
new, more flexible OpenGL recording system (glinject-next branch merged);
