    24 TVideoFrameBuffer represents a buffer for a single decoded video picture. The

    25 buffer must be contained within a chunk that can be shared across processes.

    27 The frame buffer class is used both for video renderer data flow and with the

    28 MMMFVideoClientBufferSupport extension.
