NAME
mlib_VideoDCT8x8_S16_S16_B10_NA, mlib_VideoDCT8x8_S16_S16_NA - forward
Discrete Cosine Transform (DCT)
SYNOPSIS
cc [ flag... ] file... -lmlib [ library... ]
#include <mlib.h>
mlib_status mlib_VideoDCT8x8_S16_S16_B10_NA(
mlib_s16 coeffs[64], const mlib_s16 block[64]);
mlib_status mlib_VideoDCT8x8_S16_S16_NA(
mlib_s16 coeffs[64], const mlib_s16 block[64]);
DESCRIPTION
The mlib_VideoDCT8x8_S16_S16_B10_NA() 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.
This function requires no special address alignment.
Since mediaLib 2.5, mlib_VideoDCT8x8_S16_S16_NA() has been renamed to
mlib_VideoDCT8x8_S16_S16_B10_NA(). Now mlib_VideoDCT8x8_S16_S16_NA()
is an alias of mlib_VideoDCT8x8_S16_S16_B10_NA().
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 dif‐
ference between the reference block and the current block.
RETURN VALUES
The function returns MLIB_SUCCESS if successful. Otherwise it returns
MLIB_FAILURE.
