AMVPDATAINFO structure (vptype.h)
[The feature associated with this page, DirectShow, is a legacy feature. It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation. Those features have been optimized for Windows 10 and Windows 11. Microsoft strongly recommends that new code use MediaPlayer, IMFMediaEngine and Audio/Video Capture in Media Foundation instead of DirectShow, when possible. Microsoft suggests that existing code that uses the legacy APIs be rewritten to use the new APIs if possible.]
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.
