35     * which contains unavailable physical cameras if the specified camera is a
36     * logical multi-camera.
37     *
38     * @param listener the listener interface to be added. The cameraserver will
39     *         call callbacks on this interface when a camera device's status
40     *         changes.

44     *         if the device is a logical multi-camera.
