The TDx_DrawVideoPort::Flip method will cause the video port to use a new surface for the next frame of video data.

This can be useful for preventing artifacts such as tearing.

Calls to TDx_DrawVideoPort::Flip() are asynchronous but the flips generated are synchronized with the video signals VBI.

If the method call fails, the OnError event will be triggered with one of the following values:
DDERR_INVALIDOBJECT
DDERR_INVALIDPARAMS

Surface
The Surface parameter references a surface to receive the next video frame.
Set this parameter to NULL to cycle through the flip chain in the normal attachment order.

Flags
The Flags parameter defines flags indicating the flip options.
The described effect applies when the flag is set.

DDVPFLIP_VBI
The surface referenced by the Surface property of this method will receive VBI video data.

DDVPFLIP_VIDEO
The surface referenced by the Surface property of this method will receive normal video data.
