NAME
     mlibVideoDCT16x16S16S16B10  -  forward  Discrete  Cosine
     Transform (DCT)

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

     mlibstatus mlibVideoDCT16x16S16S16B10(mlibs16 coeffs[256],
          const mlibs16 block[256]);


DESCRIPTION
     The mlibVideoDCT16x16S16S16B10() function  computes  the
     forward  DCT  for  the  destination DCT coefficients of data
     type mlibs16 and source block of data  type  mlibs16.  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 MLIBSUCES if  successful.  Otherwise
     it returns MLIBFAILURE.
