NAME
mlib_VideoDCT8x8_S16_U8_NA - forward Discrete Cosine Transform (DCT)
SYNOPSIS
cc [ flag... ] file... -lmlib [ library... ]
#include <mlib.h>
mlib_status mlib_VideoDCT8x8_S16_U8_NA(mlib_s16 coeffs[64],
const mlib_u8 *block, mlib_s32 stride);
DESCRIPTION
The mlib_VideoDCT8x8_S16_U8_NA() function computes the forward DCT for
the destination DCT coefficients of data type mlib_s16 and source block
of data type mlib_u8. The stride applies to the block that is part of
the frame currently being encoded.
This function requires no special address alignment.
This function can be used in JPEG with 8-bit precision, or in MPEG for
the intra mode.
PARAMETERS
The function takes the following arguments:
coeffs Pointer to the destination DCT coefficients.
block Pointer to an 8x8 block in the current frame.
stride Stride in bytes between adjacent rows in the block.
RETURN VALUES
The function returns MLIB_SUCCESS if successful. Otherwise it returns
MLIB_FAILURE.
