Filter8x8_H261

Performs two-dimensional filtering on a block.

Syntax

IppStatus ippiFilter8x8_H261_8u_C1R(Ipp8u* pSrc, int srcStep, Ipp8u* pDst, int dstStep);

Parameters

pSrc

Pointer to the origin of the source block.

srcStep

Width in bytes of the source image plane.

pDst

Pointer to the origin of the destination block.

dstStep

Width in bytes of the destination image plane.

Description

The function ippiFilter8x8_H261_8u_C1R is declared in the ippvc.h header file. This function performs filtering on an 8x8 block as specified in [ITUH261], subclause 3.2.3. The two-dimensional filter may be used in both encoder and decoder to modify the prediction. The application of the filter to a macroblock (to all six blocks) is signaled in the MTYPE (macroblock type) codeword.

This function is used in the H.261 encoder and decoder included into Intel IPP Samples. See introduction to H.261.

Return Values

ippStsNoErr

Indicates no error.

ippStsNullPtrErr

Indicates an error condition if at least one of the specified pointers is NULL.
