var videoTag=document.getElementById("video");
var faceDetector = new FaceDetector(
      {
          video: videoTag,
          flipLeftRight: false,
          flipUpsideDown: false
      }
  );

  faceDetector.setOnFaceAddedCallback(function (addedFaces, detectedFaces) {
      for (var i = 0; i < addedFaces.length; i++) {
          console.log("[facedetector] New face detected id=" + addedFaces[i].faceId + " index=" + addedFaces[i].faceIndex);
      }
  });

  faceDetector.setOnFaceLostCallback(function (lostFaces, detectedFaces) {
      for (var i = 0; i < lostFaces.length; i++) {
          console.log("[facedetector] Face removed id=" + lostFaces[i].faceId + " index=" + lostFaces[i].faceIndex);
      }
  });

  faceDetector.setOnFaceUpdatedCallback(function (detectedFaces) {
      for (var i = 0; i < detectedFaces.length; i++) {
          var face = detectedFaces[i];
          console.log(face.faceId+" x="+face.x+" y="+face.y+" w="+ face.width+" h="+face.height );
      }
  });

  //after getUserMedia
  faceDetector.startDetecting();

  //to stop the process (to release resources)
  faceDetector.stop();
