NAME
mlib_VideoDCT4x4_S16_S16 - forward Discrete Cosine Transform (DCT)
SYNOPSIS
cc [ flag... ] file... -lmlib [ library... ]
#include <mlib.h>
mlib_status mlib_VideoDCT4x4_S16_S16(mlib_s16 coeffs[16],
const mlib_s16 block[16]);
DESCRIPTION
The mlib_VideoDCT4x4_S16_S16() function computes the forward DCT for
the destination DCT coefficients of data type mlib_s16 and a source
block of data type mlib_s16. The input to the DCT routine is the dif‐
ference between the current block and the reference block. The differ‐
ence pixel can occupy nine bits and is represented as a 16-bit datum.
The source and destination buffer addresses must be 8-byte aligned.
PARAMETERS
The function takes the following arguments:
coeffs Pointer to the destination DCT coefficients. coeffs must be
8-byte aligned.
block Pointer to an 4x4 motion-compensated block that is the dif‐
ference between the reference block and the current block.
block must be 8-byte aligned.
RETURN VALUES
The function returns MLIB_SUCCESS if successful. Otherwise it returns
MLIB_FAILURE.
