IDirectDrawVideo::GetSurfaceType (Compact 2013)
3/26/2014
This method retrieves the actual surface type as a DirectShow DirectDraw Surface (AMDDS) definition.
Syntax
HRESULT GetSurfaceType(
DWORD* pSurfaceType
);
Parameters
pSurfaceType
Field filled in with one bit setting selected from the following list of AMDDS definitions.Definition
Description
AMDDS_NONE
No use for DCI/DirectDraw.
AMDDS_DCIPS
Use DCI primary surface.
AMDDS_PS
Use DirectDraw primary surface.
AMDDS_RGBOVR
RGB overlay surfaces.
AMDDS_YUVOVR
YUV overlay surfaces.
AMDDS_RGBOFF
RGB off-screen surfaces.
AMDDS_YUVOFF
YUV off-screen surfaces.
AMDDS_RGBFLP
RGB flipping surfaces.
AMDDS_YUVFLP
YUV flipping surfaces.
AMDDS_ALL
All the previous flags.
AMDDS_DEFAULT AMDDS_ALL
Use all available surfaces.
AMDDS_YUV
(AMDDS_YUVOFF | AMDDS_YUVOVR | AMDDS_YUVFLP).
AMDDS_RGB
(AMDDS_RGBOFF | AMDDS_RGBOVR | AMDDS_RGBFLP).
AMDDS_PRIMARY
(AMDDS_DCIPS | AMDDS_PS).
Return Value
Returns an HRESULT value.
Remarks
It is not always easy to discover which kind of surface is being used by looking at a DDSURFACEDESC structure. Therefore, an application can call GetSurfaceType to retrieve the surface type. The field will be filled in with one bit setting selected from the preceding list of AMDDS definitions.
