mediaLib Library Functions     mlib_VideoIDCT8x8_U8_S16_Q1(3MLIB)



NAME
     mlib_VideoIDCT8x8_U8_S16_Q1  -   inverse   Discrete   Cosine
     Transform

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

     mlib_status mlib_VideoIDCT8x8_U8_S16_Q1(mlib_u8 *block,
          const mlib_s16 coeffs[64], mlib_s32 stride);


DESCRIPTION
     The mlib_VideoIDCT8x8_U8_S16_Q1() function can be used  only
     when  F(u,v) are nonzero and only when 0 < u < 4 and 0 < v <
     4. 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 the current block. 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 MLIB_SUCCESS if  successful.  Otherwise
     it returns MLIB_FAILURE.

ATTRIBUTES
     See attributes(5) for descriptions of the  following  attri-
