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_VideoDCT8x8_S16_U8_NA - forward Discrete Cosine Transform (DCT) SYNOPSIS
cc [ flag... ] file... -lmlib [ library... ] #include <mlib.h> mlib_status mlib_VideoDCT8x8_S16_U8_NA(mlib_s16 coeffs[64], const mlib_u8 *block, mlib_s32 stride); DESCRIPTION
The input to the DCT routine is the difference between the current block and the reference block. The difference pixel can occupy nine bits and is represented as a 16-bit datum. This function requires no special address alignment. PARAMETERS
The function takes the following arguments: coeffs Pointer to the destination DCT coefficients. block Pointer to an 8x8 motion-compensated block that is the difference between the reference block and the current block. stride Stride in bytes between adjacent rows in a block. stride must be a multiple of eight. RETURN VALUES
The function returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE. ATTRIBUTES
