MDN’s new design is in Beta! A sneak peek:

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


The previewSizes property is an Array of objects containing the height and width properties supported for the video preview stream.


var sizes = instanceOfCameraControl.capabilities.previewSizes


Return an Array of objects.


var options = {
  camera: navigator.mozCameras.getListOfCameras()[0]
function onSuccess(camera) {
  var sizes = camera.capabilities.previewSizes;
  sizes.forEach(function (size) {
    console.log(size.width + 'x' + size.height);

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.
