mediaLib Library Functions    mlib_VideoDCT8x8_S16_S16_B10(3MLIB)



NAME
     mlib_VideoDCT8x8_S16_S16_B10,   mlib_VideoDCT8x8_S16_S16   -
     forward Discrete Cosine Transform (DCT)

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

     mlib_status mlib_VideoDCT8x8_S16_S16_B10(
          mlib_s16 coeffs[64], const mlib_s16 block[64]);


     mlib_status mlib_VideoDCT8x8_S16_S16(
          mlib_s16 coeffs[64], const mlib_s16 block[64]);


DESCRIPTION
     The  mlib_VideoDCT8x8_S16_S16_B10()  function  computes  the
     forward  DCT  for  the  destination DCT coefficients of data
     type mlib_s16 and a 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
     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,  mlib_VideoDCT8x8_S16_S16()  has  been
     renamed      to      mlib_VideoDCT8x8_S16_S16_B10().     Now
     mlib_VideoDCT8x8_S16_S16()     is      an      alias      of
     mlib_VideoDCT8x8_S16_S16_B10().

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 MLIB_SUCCESS if  successful.  Otherwise
     it returns MLIB_FAILURE.
