SimpleScreenRecorder: Powerful Screen Recording Software For Linux

SimpleScreenRecorder is a Qt screen recorder for Linux which, despite its name, comes with more features than other similar tools. The application is very easy to use and the default settings should be enough for most cases, so usually you won't need to change any settings.
Using it, you can record the entire screen (with multi-monitor support), record a fixed rectangle, follow the cursor or record OpenGL applications (can be used to record games).
