CbYCr422ToYCbCr411

Converts 4:2:2 CbYCr image to 4:1:1 YCbCr image.

Syntax

IppStatus ippiCbYCr422ToYCbCr411_8u_C2P3R(const Ipp8u* pSrc, int srcStep, Ipp8u* pDst[3], int dstStep[3], IppiSize roiSize);

Parameters

pSrc	Pointer to the source image ROI.
srcStep	Distance in bytes between starts of consecutive lines in the source image.
pDst	Array of pointers to the ROI in each plane of the destination image.
dstStep	Array of distances in bytes between starts of consecutive lines in the destination image planes.
roiSize	Size of the ROI in pixels, its width should be multiple of 4.

Description

The function ippiCbYCr422ToYCbCr411_8u_C2P3R are declared in the ippi.h file. It operates with ROI (see Regions of Interest in Intel IPP).

This function converts the 4:2:2 CbYCr two-channel image pSrc to the 4:1:1 YCbCr three-plane image pDst. The source image has the following sequence of samples: Cb0, Y0, Cr0, Y1, Cb1, Y2, Cr1, Y3, Cb2, ... . The destination image has the following order of pointers: Y-plane, Cb-plane, Cr-plane (see Table “Pixel-Order Image Formats” and Table “Planar Image Formats”).

Return Values

ippStsNoErr	Indicates no error. Any other value indicates an error.
ippStsNullPtrErr	Indicates an error condition if any of the specified pointers is NULL.
ippStsSizeErr	Indicates an error condition if roiSize.width is less than 4.
