ReconstructLumaInter8x8MB_H264, ReconstructLumaInter8x8_H264High

Reconstructs 8X8 inter luma macroblock for high profile.

Syntax

IppStatus ippiReconstructLumaInter8x8MB_H264_16s8u_C1R(Ipp16s** ppSrcDstCoeff, Ipp8u* pSrcDstYPlane, Ipp32u srcDstYStep, Ipp32u cbp8x8, Ipp32s QP, const Ipp16s* pQuantTable, Ipp8u bypassFlag);

IppStatus ippiReconstructLumaInter8x8_H264High_32s16u_IP1R(const IppiReconstructHighMB_32s16u* pReconstructInfo);

Parameters

ppSrcDstCoeff

Pointer to the order of 8x8 blocks of residual coefficients for this macroblock, which are taken as a result of Huffman decoding (8x8 luma blocks, if the block is not zero-filled) in the same order as is shown in Figure 6‑11 of [ITUH264]. Pointer is updated by the function and points to the blocks for the next macroblock.

pSrcDstYPlane

Pointer to the current macroblock that is reconstructed in current Y-plane. This macroblock must contain inter prediction samples.

srcDstStep

Plane step.

cbp8x8

Coded block pattern. If cbp8x8 & (1<<(1+i)) is not equal to 0 (0 ≤ i < 4), i-th 8x8 AC luma block is not zero-filled and it exists in ppSrcDstCoeff.

QP

Quantization parameter ( QPY in [ITUH264]). It must be within the range [0;51].

pQuantTable

Pointer to the quantization table (LevelScale(qP%6, i, j) in [ITUH264]).

bypassFlag

Flag enabling lossless coding.

pReconstructInfo

Pointer to the IppiReconstructHighMB_32s16u structure.

Description

The function ippiReconstructLumaInter8x8MB_H264_16s8u_C1R is declared in the ippvc.h file. This function reconstructs 8x8 inter luma macroblock for high profile:

This function is 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.

ippStsOutOfRangeErr

QP is less than 0 or greater than 51.
