SYNOPSIS
cc [ flag... ] file... -lmlib [ library... ]
#include <mlib.h>
mlib_status mlib_VideoIDCT8x8_U8_S16_Q1(mlib_u8 *block,
const mlib_s16 coeffs[64], mlib_s32 stride);
DESCRIPTION
The mlib_VideoIDCT8x8_U8_S16_Q1() function can be used only when F(u,v)
are nonzero and only when 0 ≤ u < 4 and 0 ≤ v < 4. The stride applies
to the block that is part of the frame currently being reconstructed.
PARAMETERS
The function takes the following arguments:
block Pointer to the current block. block must be 8-byte aligned
coeffs Pointer to the source DCT coefficients. coeffs must be 8-byte
aligned.
stride Stride, in bytes, between adjacent rows in a block. stride
must be a multiple of eight.
RETURN VALUES
The function returns MLIB_SUCCESS if successful. Otherwise it returns
MLIB_FAILURE.
