DD_CREATEMOCOMPDATA structure (ddrawint.h)

  • Article

The DD_CREATEMOCOMPDATA structure contains the data required to begin using motion compensation.

Syntax

typedef struct _DD_CREATEMOCOMPDATA {
  PDD_DIRECTDRAW_LOCAL lpDD;
  PDD_MOTIONCOMP_LOCAL lpMoComp;
  GUID                 *lpGuid;
  DWORD                dwUncompWidth;
  DWORD                dwUncompHeight;
  DDPIXELFORMAT        ddUncompPixelFormat;
  LPVOID               lpData;
  DWORD                dwDataSize;
  HRESULT              ddRVal;
} *PDD_CREATEMOCOMPDATA, DD_CREATEMOCOMPDATA;

Members

lpDD

Points to a DD_DIRECTDRAW_LOCAL structure that is relevant to the current Microsoft DirectDraw process only.

lpMoComp

Points to a DD_MOTIONCOMP_LOCAL structure that contains a description of the motion compensation object.

lpGuid

Points to a GUID that describes the motion compensation process being used.

dwUncompWidth

Specifies the width in pixels of the uncompressed output frame.

dwUncompHeight

Specifies the height in pixels of the uncompressed output frame.

ddUncompPixelFormat

Points to a DDPIXELFORMAT structure that contains the format of the uncompressed output frame.

lpData

Points to an optional data buffer that contains any optional information required by the GUID given in lpGuid. This buffer cannot contain any embedded pointers.

dwDataSize

Indicates the size in bytes of the data buffer contained in lpData.

ddRVal

Specifies the location in which the driver writes the return value of the DdMoCompCreate callback. A return code of DD_OK indicates success. For more information, see Return Values for DirectDraw.
