YUV_PARAMS

typedef struct
{
    L_UINT uStructSize;
    L_INT nMask;
    L_INT nUh;
    L_INT nUv;
    L_INT nVh;
    L_INT nVv;

The YUV_PARAMS structure provides information about YUV conversion properties. It is used to describe some YUV format to be converted to another color conversion. For more information see Generic YUV Conversion.

Parameter	Description
uStructSize	Size of this structure
nMask	Masking value. This can be any combination of the following values:
	Value	Meaning
	YUV_UH	Change the nUh value
	YUV_UV	Change the nUv value
	YUV_VH	Change the nVh value
	YUV_VV	Change the nvV value
	YUV_OFFSETS	Change the pOffsets value
	YUV_MACROPIXEL	Change the nMacroPixel value
	YUV_RANGE	Change the nRange value
nUh	Integer that represents the horizontal subsampling period of U
nUv	Integer that represents the vertical subsampling period of U.
nVh	Integer that represents the horizontal subsampling period of V.
nVv	Integer that represents the vertical subsampling period of V.

pOffsets	Pointer to integer array that represents offsets of the byte ordering for the proposed YUV format. When bPlanar is TRUE, the only useful data is pOffsets[0] which will indicate what is the arrangement of the YUV buffer. Possible values are:
	Value	Meaning
	PLANAR_YUV	Planes order, Y, U, V
	PLANAR_YVU	Planes order, Y, V, U
	PLANAR_UYV	Planes order, U, Y, V
	PLANAR_UVY	Planes order, U, V, Y
	PLANAR_VYU	Planes order, V, Y, U
	PLANAR_VUY	Planes order, V, U, Y
nMacroPixel	Macropixel size, which is the number of pixels in the unit pixels group.
nRange	Integer represents the range of values in the input buffer; full range, or 16-240 (YUVRANGE_FULL, and YUVRANGE_16_240).
bPlanar	Value that indicates whether the buffer consists of the Y plane, V plane and U plane. Possible values are:
	Value	Meaning
	TRUE	The buffer consists of the Y, U, and V planes.
	FALSE	The buffer does not consist of the Y, U, and V planes.

Comments

LPYUV_PARAMS is a pointer to a YUV_PARAMS structure. Where the function parameter type is LPYUV_PARAMS, you can declare a YUV_PARAMS variable, update the structure's fields, and pass the variable's address. Declaring a LPYUV_PARAMS variable is necessary only if your program requires a pointer.

YUV_PARAMS is used with the CONVERSION_PARAMS structure.
