CameraControl.onClosed

This API is available on Firefox OS for privileged or certified applications only.

Summary

The onClosed property is used to set an event handler that will track when a new CameraControl object in the same app takes over the camera.

Syntax

instanceOfCameraControl.onClosed = funcRef;

Where funcRef is a function to be called when the camera is taken over by another CameraControl object.

Example

var options = {
  camera: navigator.mozCameras.getListOfCameras()[0]
};
 
function onSuccess( camera ) {
  camera.onClosed = function () {
    console.log("This object is no longer able to use that camera");
  }
};

navigator.mozCameras.getCamera(options, onSuccess)

Specification

Not part of any specification; however, this API should be removed when the WebRTC Capture and Stream API has been implemented.
