        @NotNull
public @NotNull NSDictionary<java.lang.String,​?> URLAssetInitializationOptions()
        [@property] URLAssetInitializationOptions Specifies the initialization options for the creation of AVURLAssets by the receiver, e.g. AVURLAssetPreferPreciseDurationAndTimingKey. The default behavior for creation of AVURLAssets by an AVComposition is equivalent to the behavior of +[AVURLAsset URLAssetWithURL:options:] when specifying no initialization options. AVCompositions create AVURLAssets internally for URLs specified by AVCompositionTrackSegments of AVCompositionTracks, as needed, whenever AVCompositionTrackSegments were originally added to a track via -[AVMutableCompositionTrack setSegments:] rather than by inserting timeranges of already existing AVAssets or AVAssetTracks. The value of URLAssetInitializationOptions can be specified at the time an AVMutableComposition is created via +compositionWithURLAssetInitializationOptions:. API-Since: 9.0

        Description copied from class: AVAsset
        chapterMetadataGroupsBestMatchingPreferredLanguages: Tests, in order of preference, for a match between language identifiers in the specified array of preferred languages and the available chapter locales, and returns the array of chapters corresponding to the first match that's found. Safe to call without blocking when the AVAsset key availableChapterLocales has status AVKeyValueStatusLoaded. Returns an array of AVTimedMetadataGroup objects. Each object in the array always contains an AVMetadataItem representing the chapter title; the timeRange property of the AVTimedMetadataGroup object is equal to the time range of the chapter title item. All of the available chapter metadata is included in the metadata groups, including items with the common key AVMetadataCommonKeyArtwork, if such items are present. Items not carrying chapter titles will be added to an existing AVTimedMetadataGroup object if the time range (timestamp and duration) of the metadata item and that of the metadata group overlaps. The locale of such items need not match the locale of the chapter titles. Further filtering of the metadata items in AVTimedMetadataGroups according to language can be accomplished using +[AVMetadataItem metadataItemsFromArray:filteredAndSortedAccordingToPreferredLanguages:]; filtering of the metadata items according to locale can be accomplished using +[AVMetadataItem metadataItemsFromArray:withLocale:]. . API-Since: 6.0 Deprecated-Since: 100000.0
        Overrides:
        chapterMetadataGroupsBestMatchingPreferredLanguages in class AVAsset
        Parameters:
        preferredLanguages - An array of language identifiers in order of preference, each of which is an IETF BCP 47 (RFC 4646) language identifier. Use +[NSLocale preferredLanguages] to obtain the user's list of preferred languages.

        Description copied from class: AVAsset
        chapterMetadataGroupsWithTitleLocale:containingItemsWithCommonKeys: Provides an array of chapters. This method returns an array of AVTimedMetadataGroup objects. Each object in the array always contains an AVMetadataItem representing the chapter title; the timeRange property of the AVTimedMetadataGroup object is equal to the time range of the chapter title item. An AVMetadataItem with the specified common key will be added to an existing AVTimedMetadataGroup object if the time range (timestamp and duration) of the metadata item and the metadata group overlaps. The locale of items not carrying chapter titles need not match the specified locale parameter. Further filtering of the metadata items in AVTimedMetadataGroups according to language can be accomplished using +[AVMetadataItem metadataItemsFromArray:filteredAndSortedAccordingToPreferredLanguages:]; filtering of the metadata items according to locale can be accomplished using +[AVMetadataItem metadataItemsFromArray:withLocale:]. API-Since: 4.3 Deprecated-Since: 100000.0

        chapterMetadataGroupsWithTitleLocaleContainingItemsWithCommonKeys in class AVAsset
        Parameters:
        locale - Locale of the metadata items carrying chapter titles to be returned (supports the IETF BCP 47 specification).

        Description copied from class: AVAsset
        mediaSelectionGroupForMediaCharacteristic: Provides an instance of AVMediaSelectionGroup that contains one or more options with the specified media characteristic. Becomes callable without blocking when the key @"availableMediaCharacteristicsWithMediaSelectionOptions" has been loaded. If the asset has no AVMediaSelectionGroup containing options with the specified media characteristic, the return value will be nil. Filtering of the options in the returned AVMediaSelectionGroup according to playability, locale, and additional media characteristics can be accomplished using the category AVMediaSelectionOptionFiltering defined on AVMediaSelectionGroup. API-Since: 5.0 Deprecated-Since: 100000.0
        Overrides:
        mediaSelectionGroupForMediaCharacteristic in class AVAsset
        Parameters:
        mediaCharacteristic - A media characteristic for which you wish to obtain the available media selection options. AVMediaCharacteristicAudible, AVMediaCharacteristicLegible, and AVMediaCharacteristicVisual are currently supported. Pass AVMediaCharacteristicAudible to obtain the group of available options for audio media in various languages and for various purposes, such as descriptive audio. Pass AVMediaCharacteristicLegible to obtain the group of available options for subtitles in various languages and for various purposes.
