NAME

6       mlib_VideoDCT8x8_S16_S16_B12 - forward Discrete Cosine Transform (DCT)
7

SYNOPSIS

9       cc [ flag... ] file... -lmlib [ library... ]
10       #include <mlib.h>
11
12       mlib_status mlib_VideoDCT8x8_S16_S16_B12(
13            mlib_s16 coeffs[64], const mlib_s16 block[64]);

DESCRIPTION

17       This  function computes the forward DCT for the destination DCT coeffi‐
18       cients of data type mlib_s16 and source block of  data  type  mlib_s16.
19       The  source to the DCT routine can occupy up to 12 bits for each of its
20       elements.
21
22
23       The source and destination buffer addresses must be 8-byte aligned.
24
25
26       This function can be used in JPEG with 12-bit precision.
27

PARAMETERS

29       The function takes the following arguments:
30
31       coeffs    Pointer to the output DCT coefficients. Note that coeffs must
32                 be 8-byte aligned.
33
34
35       block     Pointer  to  an  8x8  block.  Note  that block must be 8-byte
36                 aligned.

38

RETURN VALUES

40       The function returns MLIB_SUCCESS if successful. Otherwise  it  returns
41       MLIB_FAILURE.
