mediaLib Library Functions    mlibVideoDCT8x8S16S16B10(3MLIB)



NAME
     mlibVideoDCT8x8S16S16B10,   mlibVideoDCT8x8S16S16   -
     forward Discrete Cosine Transform (DCT)

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

     mlibstatus mlibVideoDCT8x8S16S16B10(
          mlibs16 coeffs[64], const mlibs16 block[64]);


     mlibstatus mlibVideoDCT8x8S16S16(
          mlibs16 coeffs[64], const mlibs16 block[64]);


DESCRIPTION
     The  mlibVideoDCT8x8S16S16B10()  function  computes  the
     forward  DCT  for  the  destination DCT coefficients of data
     type mlibs16 and a 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
     can occupy nine bits and is represented as a 16-bit datum.


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


     Since  mediaLib  2.5,  mlibVideoDCT8x8S16S16()  has  been
     renamed      to      mlibVideoDCT8x8S16S16B10().     Now
     mlibVideoDCT8x8S16S16()     is      an      alias      of
     mlibVideoDCT8x8S16S16B10().

PARAMETERS
     The function takes the following arguments:

     coeffs    Pointer  to  the  destination  DCT   coefficients.
               coeffs must be 8-byte aligned.


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


RETURN VALUES
     The function returns MLIBSUCES if  successful.  Otherwise
     it returns MLIBFAILURE.
