AVCaptureMetadataInput

AVCaptureMetadataInput is a concrete subclass of AVCaptureInput that provides a way for clients to supply AVMetadataItems to an AVCaptureSession.

Instances of AVCaptureMetadataInput are input sources for AVCaptureSession that provide AVMetadataItems to an AVCaptureSession. AVCaptureMetadataInputs present one and only one AVCaptureInputPort, which currently may only be connected to an AVCaptureMovieFileOutput. The metadata supplied over the input port is provided by the client, and must conform to a client-supplied CMFormatDescription. The AVMetadataItems are supplied in an AVTimedMetadataGroup.

Returns an AVCaptureMetadataInput instance that allows a client to provide AVTimedMetadataGroups to an AVCaptureSession.

This method returns an instance of AVCaptureMetadataInput that can be used to capture AVTimedMetadataGroups supplied by the client to an AVCaptureSession.

Parameters:

desc - A CMFormatDescription that defines the metadata to be supplied by the client. Throws an NSInvalidArgumentException if NULL is passed.

clock - A CMClock that provided the timebase for the supplied samples. Throws an NSInvalidArgumentException if NULL is passed.

Returns:

An AVCaptureMetadataInput instance.

initWithFormatDescription:clock:

Creates an AVCaptureMetadataInput instance that allows a client to provide AVTimedMetadataGroups to an AVCaptureSession.

This method creates an instance of AVCaptureMetadataInput that can be used to capture AVTimedMetadataGroups supplied by the client to an AVCaptureSession.

Parameters:

desc - A CMFormatDescription that defines the metadata to be supplied by the client. Throws NSInvalidArgumentException if NULL is passed.
