NAME
     mlib_VideoDCT16x16_S16_S16_B10  -  forward  Discrete  Cosine
     Transform (DCT)

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

     mlib_status mlib_VideoDCT16x16_S16_S16_B10(mlib_s16 coeffs[256],
          const mlib_s16 block[256]);


DESCRIPTION
     The mlib_VideoDCT16x16_S16_S16_B10() function  computes  the
     forward  DCT  for  the  destination DCT coefficients of data
     type mlib_s16 and source block of data  type  mlib_s16.  The
     input  to  the  DCT  routine  is  the difference between the
     current block and the reference block. The difference  pixel
     which can occupy 10 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 a 16x16 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.

ATTRIBUTES
