    Interface Track<S, E>

    A track associated with a MainMedia (video, audio, text, markers, thumbnails, etc.).

    Tracks carry their own source, load lifecycle, and inter-track relations. Extends MediaEntity with mediaType always set to MediaEntityType.TRACK.

    interface Track<
        S extends TrackState = TrackState,
        E extends OmpEventGroup<any, any> = OmpEventGroup<any, any>,
    > {
        id: string;
        label: string | undefined;
        loadStage: OpStage;
        mediaType: MediaEntityType;
        onEvent$: Observable<E | TrackEvent<S>>;
        relations: Relation[];
        source: Source | undefined;
        sourceFileFormatType: FileFormatType | undefined;
        state: S;
        trackType: TrackType;
        addRelation(relation: Relation): void;
        hasRelation(relation: Relation): boolean;
        loadError(error: string | undefined): void;
        loadStart(): void;
        loadSuccess(): void;
        updateAttrs(attrs: TrackUpdateableAttrs): void;
    }
