the class DesktopVideoRecorder method startDesktopScreenRecording.
/**
* start Desktop Recording with a lot of parameters.
* if you have more than one monitor it will record just first one.
*
* Requirements:
* ScreenRecoder supports "AVI" and "QuickTime" format for recording the video.
* For "AVI" format you need to install TSCC Codec (Techsmith Screen Capture Codec)
* while "QuickTime" format is supported by Apple’s QuickTime Player.
