MFCreateVideoMediaTypeFromVideoInfoHeader function
Creates a media type from a KS_VIDEOINFOHEADER structure.
Syntax
HRESULT MFCreateVideoMediaTypeFromVideoInfoHeader( const KS_VIDEOINFOHEADER *pVideoInfoHeader, DWORD cbVideoInfoHeader, DWORD dwPixelAspectRatioX, DWORD dwPixelAspectRatioY, MFVideoInterlaceMode InterlaceMode, QWORD VideoFlags, const GUID *pSubtype, IMFVideoMediaType **ppIVideoMediaType );
Parameters
- pVideoInfoHeader
-
Pointer to the KS_VIDEOINFOHEADER structure to convert. (This structure is identical to the DirectShow VIDEOINFOHEADER structure.)
- cbVideoInfoHeader
-
Size of the KS_VIDEOINFOHEADER structure in bytes.
- dwPixelAspectRatioX
-
The X dimension of the pixel aspect ratio. The pixel aspect ratio is dwPixelAspectRatioX:dwPixelAspectRatioY.
- dwPixelAspectRatioY
-
The Y dimension of the pixel aspect ratio.
- InterlaceMode
-
Member of the MFVideoInterlaceMode enumeration that specifies how the video is interlaced.
- VideoFlags
-
Bitwise OR of flags from the MFVideoFlags enumeration.
- pSubtype
-
Pointer to a subtype GUID. This parameter can be NULL. If the subtype GUID is specified, the function uses it to set the media subtype. Otherwise, the function attempts to deduce the subtype from the biCompression field contained in the KS_VIDEOINFOHEADER structure.
- ppIVideoMediaType
-
Receives a pointer to the IMFVideoMediaType interface. The caller must release the interface.

If this function succeeds, it returns S_OK. Otherwise, it returns an HRESULT error code.
