/*!
    \class QVideoSurfaceFormat
    \brief The QVideoSurfaceFormat class specifies the stream format of a video presentation
    surface.
    \inmodule QtMultimedia

    \ingroup multimedia
    \ingroup multimedia_video

    A video surface presents a stream of video frames.  The surface's format describes the type of
    the frames and determines how they should be presented.

    The core properties of a video stream required to setup a video surface are the pixel format
    given by pixelFormat(), and the frame dimensions given by frameSize().

    If the surface is to present frames using a frame's handle a surface format will also include
    a handle type which is given by the handleType() function.

    The region of a frame that is actually displayed on a video surface is given by the viewport().
    A stream may have a viewport less than the entire region of a frame to allow for videos smaller
    than the nearest optimal size of a video frame.  For example the width of a frame may be
    extended so that the start of each scan line is eight byte aligned.

    Other common properties are the scanLineDirection(), and frameRate().
    Additionally a stream may have some additional type specific properties which are listed by the
    dynamicPropertyNames() function and can be accessed using the property(), and setProperty()
    functions.
*/

/*!
    \enum QVideoSurfaceFormat::Direction

    Enumerates the layout direction of video scan lines.

    \value TopToBottom Scan lines are arranged from the top of the frame to the bottom.
    \value BottomToTop Scan lines are arranged from the bottom of the frame to the top.
*/

/*!
    \enum QVideoSurfaceFormat::YCbCrColorSpace

    Enumerates the Y'CbCr color space of video frames.

    \value YCbCr_Undefined
    No color space is specified.

    \value YCbCr_BT601
    A Y'CbCr color space defined by ITU-R recommendation BT.601
    with Y value range from 16 to 235, and Cb/Cr range from 16 to 240.
    Used in standard definition video.

    \value YCbCr_BT709
    A Y'CbCr color space defined by ITU-R BT.709 with the same values range as YCbCr_BT601.  Used
    for HDTV.

    \value YCbCr_xvYCC601
    The BT.601 color space with the value range extended to 0 to 255.
    It is backward compatibile with BT.601 and uses values outside BT.601 range to represent a
    wider range of colors.

    \value YCbCr_xvYCC709
    The BT.709 color space with the value range extended to 0 to 255.

    \value YCbCr_JPEG
    The full range Y'CbCr color space used in JPEG files.
