    Interface LiveMediaSession

    Media session that also exposes live detection ingestion.

    createMediaSession returns this shape. Controllers that only satisfy the historical MediaSession contract stay assignable to it, so live ingestion is an added capability rather than a required one.

    interface LiveMediaSession {
        detectionSource?: DetectionFrameSource | WritableDetectionFrameSource;
        media: MediaSessionMediaState;
        renderer: MediaRenderer;
        appendDetectionFrames(
            frames: readonly DetectionFrame[],
            options?: MediaSessionDetectionWriteOptions,
        ): Promise<ColdDetectionFrameStoreWriteSummary>;
        replaceDetectionFrames(
            frames: readonly DetectionFrame[],
            options?: MediaSessionDetectionWriteOptions,
        ): Promise<ColdDetectionFrameStoreWriteSummary>;
        clearDetectionFrames(
            options?: MediaSessionDetectionWriteOptions,
        ): Promise<void>;
        getDetectionSummary(
            options?: MediaSessionDetectionWriteOptions,
        ): ColdDetectionFrameStoreWriteSummary | null;
        play(): Promise<void>;
        pause(): void;
        seek(mediaTime: number): Promise<void>;
        stepForward(): Promise<void>;
        stepBackward(): Promise<void>;
        setPlaybackRate(playbackRate: number): void;
        refresh(): Promise<void>;
        captureFrame(
            options?: MediaFrameCaptureOptions,
        ): Promise<MediaFrameCapture>;
        setPresentation(presentation: MediaRendererPresentation): void;
        setRenderQuality(quality: MediaRendererQuality): void;
        subscribe(
            listener: MediaSessionStateListener,
        ): MediaSessionStateUnsubscribe;
        getState(): MediaSessionState;
        destroy(): void;
        appendLiveDetectionFrame(
            frame: DetectionFrame,
            options?: MediaSessionDetectionWriteOptions,
        ): Promise<ColdDetectionFrameStoreWriteSummary>;
        finalizeDetectionCoverage(
            endTime?: number,
            options?: MediaSessionDetectionWriteOptions,
