The IDirectDrawVideoPort::Flip method instructs the DirectDrawVideoPort object to write the next frame of video to a new surface.
HRESULT Flip(
LPDIRECTDRAWSURFACE lpDDSurface,
DWORD dwFlags
);
DDVPFLIP_VIDEO | |
The specified surface is to receive the normal video data. | |
DDVPFLIP_VBI | |
The specified surface is to receive only the data within the vertical blanking interval. |
If the method succeeds, the return value is DD_OK.
If the method fails, the return value may be one of the following error values:
DDERR_INVALIDOBJECT |
DDERR_INVALIDPARAMS |
This method can be used to prevent tearing. Calls to IDirectDrawVideoPort::Flip are asynchronous—the actual flip operation will always be synchronized with the vertical blank of the video signal.
