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 pixelAspectRatio(), 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.
