YCbCr422ToCbYCr422
Converts 4:2:2 YCbCr image to 4:2:2 CbYCr image.
Syntax
IppStatus ippiYCbCr422ToCbYCr422_8u_C2R(const Ipp8u* pSrc, int srcStep, Ipp8u* pDst, int dstStep, IppiSize roiSize);
IppStatus ippiYCbCr422ToCbYCr422_8u_P3C2R(const Ipp8u* pSrc[3], int srcStep[3], Ipp8u* pDst, int dstStep, IppiSize roiSize);

Parameters
| pSrc | Pointer to the ROI in the pixel-order source image. Array of pointers to the ROI in each plane of the planar source image. | 
| srcStep | Distance in bytes between starts of consecutive lines in the source image. Array of distance values for the source image planes. | 
| pDst | Pointer to the destination image ROI. | 
| dstStep | Distance in bytes between starts of consecutive lines in the destination image. | 
| roiSize | Size of the source and destination ROI in pixels; its width should be multiple of 2. | 
Description
This function operates with ROI (see Regions of Interest in Intel IPP).
This function converts 4:2:2YCbCr source image pSrc to the 4:2:2 CbYCr two-channel image pDst that has the following sequence of samples: Cb0, Y0, Cr0, Y1, Cb1, Y2, Cr1, Y3, Cb3, ... (see Table “Pixel-Order Image Formats”). The source image can be either two-channel or three-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 of the first plane is less than 2, or roiSize.height is less than or equal to zero. |
