AMVPDATAINFO structure

The AMVPDATAINFO structure specifies the data-specific characteristics of the VP input stream.

Syntax


typedef struct _AMVPDATAINFO {
  DWORD       dwSize;
  DWORD       dwMicrosecondsPerField;
  AMVPDIMINFO amvpDimInfo;
  DWORD       dwPictAspectRatioX;
  DWORD       dwPictAspectRatioY;
  BOOL        bEnableDoubleClock;
  BOOL        bEnableVACT;
  BOOL        bDataIsInterlaced;
  LONG        lHalfLinesOdd;
  BOOL        bFieldPolarityInverted;
  DWORD       dwNumLinesInVREF;
  LONG        lHalfLinesEven;
  DWORD       dwReserved1;
} AMVPDATAINFO, *LPAMVPDATAINFO;

Members

dwSize

Size of the structure, in bytes.

dwMicrosecondsPerField

Time taken by each field.

amvpDimInfo

Dimensional information.

dwPictAspectRatioX

The X dimension of picture aspect ratio.

dwPictAspectRatioY

The Y dimension of picture aspect ratio.

bEnableDoubleClock

Video port should enable double clocking.

bEnableVACT

Video port should use an external VACT signal.

bDataIsInterlaced

Indicates that the signal is interlaced.

lHalfLinesOdd

Number of half lines in the odd field.

bFieldPolarityInverted

Video port should invert the field polarity.

dwNumLinesInVREF

Number of lines of data in VREF.

lHalfLinesEven

Number of half lines in the even field.

dwReserved1

Reserved for future use.
