NAME

6       mlib_VideoIDCT8x8_U8_S16_Q1 - inverse Discrete Cosine Transform
7

SYNOPSIS

9       cc [ flag... ] file... -lmlib [ library... ]
10       #include <mlib.h>
11
12       mlib_status mlib_VideoIDCT8x8_U8_S16_Q1(mlib_u8 *block,
13            const mlib_s16 coeffs[64], mlib_s32 stride);

DESCRIPTION

17       The mlib_VideoIDCT8x8_U8_S16_Q1() function can be used only when F(u,v)
18       are nonzero and only when 0 ≤ u < 4 and 0 ≤ v < 4. The  stride  applies
19       to the block that is part of the frame currently being reconstructed.
20

PARAMETERS

22       The function takes the following arguments:
23
24       block     Pointer to the current block. block must be 8-byte aligned
25
26
27       coeffs    Pointer to the source DCT coefficients. coeffs must be 8-byte
28                 aligned.
29
30
31       stride    Stride, in bytes, between adjacent rows in  a  block.  stride
32                 must be a multiple of eight.

34

RETURN VALUES

36       The  function  returns MLIB_SUCCESS if successful. Otherwise it returns
37       MLIB_FAILURE.
