NAME

mlib_VideoIDCT8x8_U8_S16_NA - inverse Discrete Cosine Transform  

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.
