NAME
       mlib_VideoDCT8x8_S16_S16_B12 - forward Discrete Cosine Transform (DCT)

SYNOPSIS
       cc [ flag... ] file... -lmlib [ library... ]
       #include <mlib.h>

       mlib_status mlib_VideoDCT8x8_S16_S16_B12(mlib_s16 coeffs[64], const mlib_s16 block[64]);

DESCRIPTION
       Purpose	This  function	computes  the forward DCT for the destination DCT coefficients of data type mlib_s16 and source block of data type
       mlib_s16.  The source to the DCT routine is the difference between the current block and the reference block. The difference  pixel,  which
       can occupy 12 bits, is represented as a 16-bit data.

PARAMETERS
       The function takes the following arguments:

       coeffs	       Pointer to the output DCT coefficients. Note that coeffs must be 8-byte aligned.

       block	       Pointer	to an 8x8 motion-compensated block which is the difference between the reference block and the current block. Note
		       that block must be 8-byte aligned.

RETURN VALUES
       The function returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE.
