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.
