NAME
     mlib_VideoDCT8x8_S16_S16_B12  -  forward   Discrete   Cosine
     Transform (DCT)

SYNOPSIS
     cc [ flag... ] file... -lmlib [ library... ]
     #include 

     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  coefficients  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.

ATTRIBUTES
     See attributes(5) for descriptions of the  following  attri-
