Flipping Overlay Surfaces (Windows Embedded CE 6.0)
1/6/2010
Like other types of surfaces, you can create overlay flipping chains. After creating a flipping chain of overlays, call the IDirectDrawSurface::Flip method to flip between them. For more information, see Flipping Surfaces.
Software decoders displaying video with overlay surfaces can use the DDFLIP_ODD and DDFLIP_EVEN flags when calling the Flip method to use capabilities that reduce motion artifacts.
If the driver supports odd-even flipping, the DDMISCCAPS_FLIPODDEVEN flag will be set in the DDCAPS structure after retrieving driver capabilities.
