inputPriority constant
A CaptureSession preset indicating that the formats of the session's inputs are being given priority.
By calling CaptureSession.setSessionPreset, clients can easily
configure a CaptureSession to produce a desired quality of service
level. The session configures its inputs and outputs optimally to produce
the QoS level indicated. Clients who need to ensure a particular input
format is chosen can use CaptureDevice.setActiveFormat method. When a
client sets the active format on a device, the associated session's
setSessionPreset method automatically changes to
CaptureSessionPreset.inputPriority. This change indicates that the input
format selected by the client now dictates the quality of service level
provided at the outputs. When a client sets the session preset to anything
other than CaptureSessionPreset.inputPriority, the session resumes
responsibility for configuring inputs and outputs, and is free to change
its inputs' activeFormat as needed.
Implementation
static const String inputPriority = 'AVCaptureSessionPresetInputPriority';
