This feature is not on a current W3C standards track, but it is supported on the Firefox OS platform. Although implementations may change in the future and it is not supported widely across browsers, it is suitable for use in code dedicated to Firefox OS apps.

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


The videoSizes property is an Array of objects containing the height and width properties supported for video recording.


var sizes = instanceOfCameraControl.capabilities.videoSizes


Return an Array of objects.


var options = {
  camera: navigator.mozCameras.getListOfCameras()[0]
function onSuccess(camera) {
  var sizes = camera.capabilities.videoSizes;
  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.
