Like other types of surfaces, you can create overlay flipping chains. After creating a flipping chain of overlays, call the IDirectDrawSurface7::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 features that reduce motion artifacts. If the driver supports odd-even flipping, the DDCAPS2_CANFLIPODDEVEN flag will be set in the DDCAPS structure after retrieving driver capabilities. If DDCAPS2_CANFLIPODDEVEN is set, you can include the DDOVER_BOB flag when calling the IDirectDrawSurface7::UpdateOverlay method to inform the driver that you want it to use the "Bob" algorithm to minimize motion artifacts. Later, when you call Flip with the DDFLIP_ODD or DDFLIP_EVEN flag, the driver will automatically adjust the overlay source rectangle to compensate for jittering artifacts.
