====== Screensharing ======
Using webRTC you can transmit an image of your screen instead of the camera image. You can transmit the image of your entire screen or select a specific window to transmit only that window's contents. webRTC treats the user's screen as a virtual camera, transmitting a video screen. Thus receiving end can //see// what's on the screen but cannot //alter// it, eg moving the mouse or typing anything.

===== Start screen sharing =====
When screen sharing is started by calling [[ixnx:wrtc:js:api:wrtc:getscreen|wrtc.getScreen(true)]]. User is then presented with a list of choices to share the entire screen or just one specific window.

===== Stop screen sharing =====
To stop screen sharing and transmit local camera image again call [[ixnx:wrtc:js:api:wrtc:getscreen|wrtc.getScreen(false)]].
