A capture session that supports simultaneous capture from multiple inputs of the same media type.
Mac Catalyst 13.0+
The session preset for a multicamera session is always inputPriority. Set each capture device’s activeFormat value to the desired quality of service.
You can dynamically enable and disable this session’s individual camera inputs without interrupting capture preview. To stop an individual camera, disable all of its connections or connected ports. The camera then stops streaming data to save power and bandwidth. Other inputs that are streaming data through the session are unaffected.
