NAME
     mlib_VideoIDCT8x8_S16_S16_Q1_Mismatch  -  inverse   Discrete
     Cosine Transform

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

     mlib_status mlib_VideoIDCT8x8_S16_S16_Q1_Mismatch(
          mlib_s16 block[64], const mlib_s16 coeffs[64]);


DESCRIPTION
     The  mlib_VideoIDCT8x8_S16_S16_Q1_Mismatch()  function  com-
     putes the inverse IDCT in the inter mode.


     This function is similar  to  mlib_VideoIDCT8x8_S16_S16_Q1()
     which  should  only be used when coeffs[u][v]  (u,v = 0...7)
     are non-zero only for u and v less  then  4.  However,  this
     function  also  allows  element coeffs[7][7] to be non-zero.
     The primary benefit of this modification is that it can han-
     dle  situations where coeffs[7][7] has been made non-zero by
     MPEG mismatch-control, allowing a simplified version of  the
     IDCT  to  be  undertaken  for a much larger number of situa-
     tions.

PARAMETERS
     The function takes the following arguments:

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


     coeffs    Pointer to the input DCT coefficients. coeffs must
               be  8-byte  aligned. coeffs should be in S12 range
               or it should be obtained  from  the  corresponding
               forward DCT.


RETURN VALUES
     The function returns MLIB_SUCCESS if  successful.  Otherwise
     it returns MLIB_FAILURE.
