Class AVPlayerItemMetadataCollector

  • All Implemented Interfaces:
    NSObject
    public class AVPlayerItemMetadataCollector
extends AVPlayerItemMediaDataCollector
    AVPlayerItemMetadataCollector A subclass of AVPlayerItemMediaDataCollector that provides AVMetadataGroups for an AVPlayerItem. This class can be used to inform clients of the current set of AVMetadataGroups on an AVPlayerItem, and when new AVMetadataGroups become available - e.g. in a Live HLS stream. Subclasses of this type that are used from Swift must fulfill the requirements of a Sendable type. API-Since: 9.3

      • delegate

        @Nullable
public @Nullable AVPlayerItemMetadataCollectorPushDelegate 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

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

                                                                          @Nullable NSArray<java.lang.String> identifiers,
                                                                          @Nullable
                                                                          @Nullable NSArray<java.lang.String> classifyingLabels)
        initWithIdentifiers:classifyingLabels: Returns an instance of AVPlayerItemMetadataCollector that can provide all available AVMetadataGroups matching a set of criteria. Some metadata available in some formats - such as timed metadata embedded in HLS segments - is not available for collector output. The default init method can be used as an alternative to setting both identifiers and classifyingLabels to nil.
        Parameters:
        identifiers - A array of metadata identifiers indicating the metadata items that the output should provide. See AVMetadataIdentifiers.h for publicly defined metadata identifiers. Pass nil to include metadata with any identifier.
        classifyingLabels - If the metadata format supports labeling each metadata group with a string, supplying an array of group labels indicates that the output should provide metadata groups that match one of the supplied labels. Pass nil to include metadata with any (or no) classifying label.
        Returns:
        An instance of AVPlayerItemMetadataCollector.

      • setDelegateQueue

        public void setDelegateQueue​(@Nullable
                             @Nullable AVPlayerItemMetadataCollectorPushDelegate delegate,
                             @Nullable
                             @Nullable dispatch_queue_t 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 AVPlayerItemMetadataCollectorPushDelegate protocol.
        delegateQueue - A dispatch queue on which all delegate methods will be called.
