Detailed Description#

A video sink presents a stream of video frames. QVideoFrameFormat describes the type of the frames and determines how they should be presented.

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

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() , frameRate() and the yCrCbColorSpace().
