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


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.


instanceOfCameraControl.onClosed = funcRef;

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


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)


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