NAME
mlib_VideoDCT16x16_S16_S16 - forward Discrete Cosine Transform (DCT)
SYNOPSIS
cc [ flag... ] file... -lmlib [ library... ]
#include <mlib.h>
mlib_status mlib_VideoDCT16x16_S16_S16(mlib_s16 coeffs[256],
const mlib_s16 block[256]);
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. 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 16x16 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.
