    Interface ReadonlyAmznPlaybackStreamingState

    Extends ReadonlyPlaybackStreamingState with Amazon-specific streaming metadata.

    This interface provides additional metadata around Amazon-specific playback behavior, such as:

    • Internal playback quality metadata (nerd stats)
    • The reason behind current quality selection

    All properties are read-only and reflect the current snapshot of the active Amazon track. These values will be null for non-Amazon tracks.

    interface ReadonlyAmznPlaybackStreamingState {
        contentTypes: Readonly<
            Omit<Set<ContentType>, "clear" | "delete" | "add">,
        >;
        fetchedRanges: ReadonlyRanges;
        fetchedTime: number;
        fetchedTimePercent: number;
        playbackQualityAmzn: null | AmazonPlaybackQuality;
        trackNerdStats: null | TrackNerdStats;
        getBufferingQuality(contentType: ContentType): null | MediaQualityMetadata;
        getPlaybackQuality(contentType: ContentType): null | MediaQualityMetadata;
        getQualitySelectionReason(): null | QualitySelectionReason;
        getStreamingQuality(contentType: ContentType): null | MediaQualityMetadata;
        hasAnyListeners(): boolean;
        hasListeners(type: keyof StreamingEventMap): boolean;
        on<K extends keyof StreamingEventMap>(
            type: K,
            handler: EventHandler<StreamingEventMap[K]>,
            options?: SignalOptions,
        ): Unsubscribe;
    }
