DD_GETVPORTOUTPUTFORMATDATA structure (ddrawint.h)

  • Article

The DD_GETVPORTOUTPUTFORMATDATA structure contains the information required for the driver to return all of the output formats that the video port extensions (VPE) object supports for a given input format.

Syntax

typedef struct _DD_GETVPORTOUTPUTFORMATDATA {
  PDD_DIRECTDRAW_LOCAL lpDD;
  PDD_VIDEOPORT_LOCAL  lpVideoPort;
  DWORD                dwFlags;
  LPDDPIXELFORMAT      lpddpfInputFormat;
  LPDDPIXELFORMAT      lpddpfOutputFormats;
  DWORD                dwNumFormats;
  HRESULT              ddRVal;
  VOID                 *GetVideoPortInputFormats;
} *PDD_GETVPORTOUTPUTFORMATDATA, DD_GETVPORTOUTPUTFORMATDATA;

Members

lpDD

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

lpVideoPort

Points to the DD_VIDEOPORT_LOCAL structure that represents this VPE object.

dwFlags

Indicates the type of output formats for which support is being queried. This member can be one or more of the following values:

Flag Meaning
DDVPFORMAT_VBI The driver should return formats for the VBI data.
DDVPFORMAT_VIDEO The driver should return formats for the video data.

lpddpfInputFormat

Points to a DDPIXELFORMAT structure that contains an input format supported by the VPE object. This format was returned by DdVideoPortGetInputFormats.

lpddpfOutputFormats

Points to an array of DDPIXELFORMAT structures in which the driver should return the output formats that the VPE object supports for the input format specified by lpddpfInputFormat. This member can be NULL.

dwNumFormats

Specifies the location in which the driver should return the number of output formats that the VPE object supports for the specified input format.

ddRVal

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