Specifies that the capture session does not control audio and video output settings.

To enable capture settings not supported by any session presets (such as high frame rate), change the value of the
active property on the appropriate capture device. When you change the device’s format, the session preset automatically changes to this value, indicating that the
AVCapture object has relinquished responsibility for configuring its inputs and outputs. (Instead, the capture device’s active format dictates the quality of service level provided at the outputs). To return to automatic configuration, use the session’s
session property to choose another preset.
