Parameters
pSrc
Array of pointers to the ROI in each plane of the source image.
srcStep
Array of distances in bytes between starts of consecutive lines in each plane of 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 each plane of the destination image.
roiSize
Size of the ROI in pixels, its width should be multiple of 2, its height should be multiple of 8.
Description
This function operates with ROI (see Regions of Interest in Intel IPP).
This function converts the
4:2:0
YCrCb
three-plane image
pSrc
to the
4:2:2
YCbCr
three-plane image
pDst
(see Table
“Planar Image Formats”
).
Additionally, this function performs the vertical upsampling using a Catmull-Rom interpolation (cubic convolution interpolation).
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 2 or
roiSize.height
is less than 8.

Product and Performance Information

Intel's compilers may or may not optimize to the same degree for non-Intel microprocessors for optimizations that are not unique to Intel microprocessors. These optimizations include SSE2, SSE3, and SSSE3 instruction sets and other optimizations. Intel does not guarantee the availability, functionality, or effectiveness of any optimization on microprocessors not manufactured by Intel. Microprocessor-dependent optimizations in this product are intended for use with Intel microprocessors. Certain optimizations not specific to Intel microarchitecture are reserved for Intel microprocessors. Please refer to the applicable product User and Reference Guides for more information regarding the specific instruction sets covered by this notice.
