This 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;
