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
       This  function computes the forward DCT for the destination DCT coeffi‐
       cients of data type mlib_s16 and source block of	 data  type  mlib_s16.
       The  source to the DCT routine can occupy up to 12 bits for each of its
       elements.

       The source and destination buffer addresses must be 8-byte aligned.

       This function can be used in JPEG with 12-bit precision.

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  block.  Note  that block must be 8-byte
		 aligned.

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