      • advanceIntervalForDelegateInvocation

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

      • delegate

        @Nullable
public @Nullable AVPlayerItemLegibleOutputPushDelegate 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 where the delegate is messaged. This property is not key-value observable.

      • initWithMediaSubtypesForNativeRepresentation

        public AVPlayerItemLegibleOutput initWithMediaSubtypesForNativeRepresentation​(@NotNull
                                                                              @NotNull NSArray<? extends NSNumber> subtypes)
        initWithMediaSubtypesForNativeRepresentation: Returns an instance of AVPlayerItemLegibleOutput with filtering enabled for AVPlayerItemLegibleOutputPushDelegate's legibleOutput:didOutputAttributedStrings:nativeSampleBuffers:forItemTime:. Add media subtype FourCC number objects to the subtypes array to elect to receive that type as a CMSampleBuffer instead of an NSAttributedString. Initializing an AVPlayerItemLegibleOutput using the -init method is equivalent to calling -initWithMediaSubtypesForNativeRepresentation: with an empty array, which means that all legible data, regardless of media subtype, will be delivered using NSAttributedString in a common format. If a media subtype for which there is no legible data in the current player item is included in the media subtypes array, no error will occur. AVPlayerItemLegibleOutput will not vend closed caption data as CMSampleBuffers, so it is an error to include 'c608' in the media subtypes array. This method throws an exception if any media subtype is kCMClosedCaptionFormatType_CEA608 (native representation is not available for media subtype).
        Parameters:
        subtypes - NSArray of NSNumber FourCC codes, e.g. @[ [NSNumber numberWithUnsignedInt:'tx3g'] ]
        Returns:
        An instance of AVPlayerItemLegibleOutput.

      • setAdvanceIntervalForDelegateInvocation

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

      • setDelegateQueue

        public void setDelegateQueue​(@Nullable
                             @Nullable AVPlayerItemLegibleOutputPushDelegate 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. The delegate is held using a zeroing-weak reference, so it is safe to deallocate the delegate while the receiver still has a reference to it.
        Parameters:
        delegate - An object conforming to AVPlayerItemLegibleOutputPushDelegate protocol.
        delegateQueue - A dispatch queue on which all delegate methods will be called.

      • setTextStylingResolution

        public void setTextStylingResolution​(@NotNull
                                     @NotNull java.lang.String value)
        [@property] textStylingResolution A string identifier indicating the degree of text styling to be applied to attributed strings vended by the receiver Valid values are AVPlayerItemLegibleOutputTextStylingResolutionDefault and AVPlayerItemLegibleOutputTextStylingResolutionSourceAndRulesOnly. An NSInvalidArgumentException is raised if this property is set to any other value. The default value is AVPlayerItemLegibleOutputTextStylingResolutionDefault, which indicates that attributed strings vended by the receiver will include the same level of styling information that would be used if AVFoundation were rendering the text via AVPlayerLayer.
