NAME
     mlibVideoIDCT8x8U8S16 - inverse Discrete Cosine Transform

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

     mlibstatus mlibVideoIDCT8x8U8S16(mlibu8 *block,
          const mlibs16 coeffs[64], mlibs32 stride);


DESCRIPTION
     The mlibVideoIDCT8x8U8S16() function computes the inverse
     DCT  (called  IDCT)  for  the destination IDCT block of data
     type mlibu8  and  source  DCT  coefficients  of  data  type
     mlibs16.


     The stride applies to the block that is part  of  the  frame
     currently being reconstructed.

PARAMETERS
     The function takes the following arguments:

     block     Pointer to an 8x8  block  in  the  current  frame.
               block must be 8-byte aligned.


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


     stride    Stride, in  bytes,  between  adjacent  rows  in  a
               block. stride must be a multiple of eight.


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