SYNOPSIS
cc [ flag... ] file... -lmlib [ library... ]
#include <mlib.h>
mlib_status mlib_VideoIDCT8x8_U8_S16_NA(mlib_u8 *block,
const mlib_s16 coeffs[64], mlib_s32 stride);
DESCRIPTION
The mlib_VideoIDCT8x8_U8_S16_NA() function computes the inverse DCT
(called IDCT) for the destination IDCT block of data type mlib_u8 and
source DCT coefficients of data type mlib_s16.
The stride applies to the block that is part of the frame currently
being reconstructed.
This function requires no special address alignment.
PARAMETERS
The function takes the following arguments:
block Pointer to the current block.
coeffs Pointer to the source DCT coefficients.
stride Stride, in bytes, between adjacent rows in the block.
RETURN VALUES
The function returns MLIB_SUCCESS if successful. Otherwise it returns
MLIB_FAILURE.
