Performs inverse quantization for 8X8 luma block coefficients including normalization of the subsequent inverse 8X8 transform.
IppStatus ippiQuantLuma8x8Inv_H264_16s_C1I(Ipp16s* pSrcDst, int Qp6, const Ipp16s* pInvLevelScale);
pSrcDst |
Pointer to luma block coefficients - source and destination array of size 64. |
Qp6 |
Quantization parameter divided by 6. |
pInvLevelScale |
Pointer to an inverse scale level matrix. |
The function ippiQuantLuma8x8Inv_H264_16s_C1I is declared in the ippvc.h file. This function performs inverse quantization and normalization for 8x8 inverse transform of luma block coefficients according to 8.5.13 of [ITUH264].
ippStsNoErr |
Indicates no error. |
ippStsNullPtrErr |
Indicates an error condition if at least one of the specified pointers is NULL. |
ippStsQPErr |
Indicates an error condition if Qp6 is less than 0 or greater than 8. |
