Stream Control

start_stream​

After a presentation ends, re-start the local stream with the previously active options.
It can also be used after devices are changed. See Device Manager for further information.
If screen = true, video => false.

eyeson.send({
  type: 'start_stream',
  audio: true | false, // default: true
  video: true | false, // default: true
  screen: true | false, // default: false
  virtualBackground: true | false, // default: false
});

The screen parameter is used to switch from camera to screen stream. Use the surface option to pre-select the desired options. Skip or set null for browser default. Detect availablility for UI with FeatureDetector.canChooseDisplaySurface(). More info.

eyeson.send({
  type: 'start_stream',
  audio: true | false, // set true to add microphone
  screen: true,
  surface: null | 'monitor' | 'window' | 'browser' // optional; used only if screen=true
});
