NAME

mlib_VideoQuantizeInit_S16 - quantization of forward Discrete Cosine Transform (DCT) coefficients  

SYNOPSIS

cc [ flag... ] file... -lmlib [ library... ]
#include <mlib.h>

mlib_status mlib_VideoQuantizeInit_S16(mlib_d64 dqtable[64],
    const mlib_s16 iqtable[64]);

 

DESCRIPTION

The mlib_VideoQuantizeInit_S16() function initializes the quantization table.

The following equation is used:

dqtable[i] = 1.0 / iqtable[i];  0 ≤ i < 64

 

PARAMETERS

The function takes the following arguments:

dqtable

Pointer to quantizer 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.
