On single-camera devices, this value is always
1. On a dual-camera device, the allowed range of video zoom factors can change if the device is delivering depth data to one or more capture outputs.
video property to (or calling the

1 always raises an exception. Setting the video zoom factor to a value between
1 and the minimum available zoom factor clamps the zoom setting to the minimum.
This property is key-value observable.
