NAME
       mlib_VideoIDCT8x8_S16_S16_Q1_Mismatch - inverse Discrete Cosine Transform

SYNOPSIS
       cc [ flag... ] file... -lmlib [ library... ]
       #include <mlib.h>

       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 computes 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 handle 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 situations.

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 correspondent direct DCT.

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