NAME
mlib_VideoIDCT8x8_U8_S16_NA - inverse Discrete Cosine
TransformSYNOPSIS
cc [ flag... ] file... -lmlib [ library... ]
#include
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 ofdata 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.
