Enum "GstFaceDetectUpdates" Default: 0, "every_frame"
(0): every_frame      - Send update messages on every frame
(1): on_change        - Send update messages on change (face detected/not
detected)
(2): on_face          - Send update messages when a face is detected
(3): none             - Send no messages update

What if the face was detected changed position or if the number of detected
faces change? I guess this "on_change" needs a better definition.
