mlib_VideoDeQuantizeInit_S16 - dequantization of forward Discrete Cosine Transform (DCT) coefficients SYNOPSIS
cc [ flag... ] file... -lmlib [ library... ] #include <mlib.h> mlib_status mlib_VideoDeQuantizeInit_S16(mlib_d64 dqtable[64], const mlib_s16 iqtable[64]); DESCRIPTION
The mlib_VideoDeQuantizeInit_S16() function initializes the dequantization table. The following equation is used: dqtable[i] = iqtable[i]; 0 <= i < 64 PARAMETERS
The function takes the following arguments: dqtable Pointer to dequantizer table coefficients. iqtable Pointer to original quantizer table coefficients: 0 < iqtable[i] < 128 RETURN VALUES
The function returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE. ATTRIBUTES

mlib_VideoQuantize_S16 - quantization of forward Discrete Cosine Transform (DCT) coefficients SYNOPSIS
cc [ flag... ] file... -lmlib [ library... ] #include <mlib.h> mlib_status mlib_VideoQuantize_S16(mlib_s16 icoeffs[64], const mlib_d64 dqtable[64]); DESCRIPTION
The mlib_VideoQuantize_S16() function performs quantization on DCT coefficients. The following equation is used: icoeffs[i] = icoeffs[i] * dqtable[i]; 0 <= i < 64 PARAMETERS
The function takes the following arguments: icoeffs Pointer to the output DCT coefficients: -2048 < icoeffs[i] < 2048 Note that icoeffs must be 8-byte aligned. dqtable Pointer to quantizer table coefficients. RETURN VALUES
The function returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE. ATTRIBUTES
