-// Class used by VideoCaptureDeviceMac (VCDM) for video and image capture using
-// AVFoundation API. This class lives inside the thread created by its owner
-// VCDM.
-//
-//  * Clients (VCDM) should call +deviceNames to fetch the list of devices
-//    available in the system; this method returns the list of device names that
-//    have to be used with -setCaptureDevice:.
-//  * Previous to any use, clients (VCDM) must call -initWithFrameReceiver: to
-//    initialise an object of this class and register a |frameReceiver_|.
-//  * Frame receiver registration or removal can also happen via explicit call
-//    to -setFrameReceiver:. Re-registrations are safe and allowed, even during
-//    capture using this method.
-//  * Method -setCaptureDevice: must be called at least once with a device
-//    identifier from +deviceNames. Creates all the necessary AVFoundation
-//    objects on first call; it connects them ready for capture every time.
-//    This method should not be called during capture (i.e. between
-//    -startCapture and -stopCapture).
-//  * -setCaptureWidth:height:frameRate: is called if a resolution or frame rate
-//    different than the by default one set by -setCaptureDevice: is needed.
-//    This method should not be called during capture. This method must be
-//    called after -setCaptureDevice:.
-//  * -startCapture registers the notification listeners and starts the
-//    capture. The capture can be stop using -stopCapture. The capture can be
-//    restarted and restoped multiple times, reconfiguring or not the device in
-//    between.
-//  * -setCaptureDevice can be called with a |nil| value, case in which it stops
-//    the capture and disconnects the library objects. This step is not
-//    necessary.
-//  * Deallocation of the library objects happens gracefully on destruction of
-//    the VideoCaptureDeviceAVFoundation object.
