Calculate average value for each source pair values in block.
Syntax
IppStatus ippiInterpolateBlock_H264_8u_P2P1R(const Ipp8u* pSrc1, const Ipp8u* pSrc2, Ipp8u* pDst, Ipp32u width, Ipp32u height, Ipp32u pitch);
IppStatus ippiInterpolateBlock_H264_8u_P3P1R(const Ipp8u* pSrc1, const Ipp8u* pSrc2, Ipp8u* pDst, Ipp32u width, Ipp32u height, Ipp32s srcStep1, Ipp32s srcStep2, Ipp32s dstStep);
IppStatus ippiBidir_H264_16u_P2P1R(IppVCBidir_16u* bidirInfo);
Parameters
pSrc1 |
Pointer to the first input block. |
pSrc2 |
Pointer to the second input block. |
pDst |
Pointer to the first output block. |
width |
Number of values in the block line. |
height |
Number of lines in the block. |
srcStep1 |
Distance in items between starts of the consecutive lines in the first input block. |
srcStep2 |
Distance in items between starts of the consecutive lines in the second input block. |
dstStep |
Distance in items between starts of the consecutive lines in the first output block. |
pitch |
Memory pitch. |
bidirInfo |
Pointer to the IppVCBidir_16u structure. |
Description
The functions ippiInterpolateBlock_H264_8u_P2P1R, ippiInterpolateBlock_H264_8u_P3P1R, and ippiBidir_H264_16u_P2P1R are declared in the ippvc.h file. These functions calculate the average value for each corresponding source pair values in a block with height lines and width values per line.
These functions are used in the H.264 decoder included into Intel IPP Samples. See introduction to H.264.
Return Values
ippStsNoErr |
Indicates no error. |
ippStsNullPtrErr |
Indicates an error condition if at least one of the specified pointers is NULL. |
