  • All Implemented Interfaces:
    NSObject
    public class AVPlayerItemMetadataOutput
extends AVPlayerItemOutput
    AVPlayerItemMetadataOutput A subclass of AVPlayerItemOutput that vends collections of metadata items carried in metadata tracks. Setting the value of suppressesPlayerRendering on an instance of AVPlayerItemMetadataOutput has no effect.

      • advanceIntervalForDelegateInvocation

        public double advanceIntervalForDelegateInvocation()
        [@property] advanceIntervalForDelegateInvocation Permits advance invocation of the associated delegate, if any. If it is possible, an AVPlayerItemMetadataOutput will message its delegate advanceIntervalForDelegateInvocation seconds earlier than otherwise. If the value you provide is large, effectively requesting provision of samples earlier than the AVPlayerItemMetadataOutput is prepared to act on them, the delegate will be invoked as soon as possible.

      • delegate

        public AVPlayerItemMetadataOutputPushDelegate delegate()
        [@property] delegate The receiver's delegate. The delegate is held using a zeroing-weak reference, so this property will have a value of nil after a delegate that was previously set has been deallocated. This property is not key-value observable.

      • delegateQueue

        public NSObject delegateQueue()
        [@property] delegateQueue The dispatch queue on which messages are sent to the delegate. This property is not key-value observable.

      • initWithIdentifiers

        public AVPlayerItemMetadataOutput initWithIdentifiers​(NSArray<java.lang.String> identifiers)
        initWithIdentifiers: Creates an instance of AVPlayerItemMetadataOutput. See AVMetadataIdentifiers.h for publicly defined metadata identifiers. Pass nil to receive all of the timed metadata from all enabled AVPlayerItemTracks that carry timed metadata.
        Parameters:
        identifiers - A array of metadata identifiers indicating the metadata items that the output should provide.

      • setAdvanceIntervalForDelegateInvocation

        public void setAdvanceIntervalForDelegateInvocation​(double value)
        [@property] advanceIntervalForDelegateInvocation Permits advance invocation of the associated delegate, if any. If it is possible, an AVPlayerItemMetadataOutput will message its delegate advanceIntervalForDelegateInvocation seconds earlier than otherwise. If the value you provide is large, effectively requesting provision of samples earlier than the AVPlayerItemMetadataOutput is prepared to act on them, the delegate will be invoked as soon as possible.

      • setDelegateQueue

        public void setDelegateQueue​(AVPlayerItemMetadataOutputPushDelegate delegate,
                             NSObject delegateQueue)
        setDelegate:queue: Sets the receiver's delegate and a dispatch queue on which the delegate will be called.
        Parameters:
        delegate - An object conforming to AVPlayerItemMetadataOutputPushDelegate protocol.
        delegateQueue - A dispatch queue on which all delegate methods will be called.
