    Interface MediaFrameDiagnostics

    Per-presented-frame diagnostics.

    Emitted from a renderer's frame loop. Keep handlers lightweight if reading diagnostics at high frequency.

    estimatedFrameIndex: number | null

    Zero-based display estimate derived from the opened source's packet rate. Canonical frame identity remains mediaTime, especially for VFR media.

    frameDuration: number

    Duration reported by the decoded sample currently on screen.

    firstTimestamp: number

    First playable presentation timestamp of the opened media source.
