mlib_VideoDCT8x8_S16_S16_B10, mlib_VideoDCT8x8_S16_S16 - forward Dis‐
crete Cosine Transform (DCT)
SYNOPSIS
cc [ flag... ] file... -lmlib [ library... ]
#include <mlib.h>
mlib_status mlib_VideoDCT8x8_S16_S16_B10(
mlib_s16 coeffs[64], const mlib_s16 block[64]);
mlib_status mlib_VideoDCT8x8_S16_S16(
mlib_s16 coeffs[64], const mlib_s16 block[64]);
DESCRIPTION
The mlib_VideoDCT8x8_S16_S16_B10() 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.
Since mediaLib 2.5, mlib_VideoDCT8x8_S16_S16() has been renamed to
mlib_VideoDCT8x8_S16_S16_B10(). Now mlib_VideoDCT8x8_S16_S16() is an
alias of mlib_VideoDCT8x8_S16_S16_B10().
PARAMETERS
The function takes the following arguments:
coeffs Pointer to the destination DCT coefficients. coeffs must be
8-byte aligned.
block Pointer to an 8x8 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.
