DESCRIPTION

17       The  mlib_VideoIDCT8x8_S16_S16_DC()  function  can  be  used  only when
18       F(0,0) is nonzero. It computes the inverse DCT (called  IDCT)  for  the
19       output  IDCT  block of data type mlib_s16 and input DCT coefficients of
20       data  type  mlib_s16.  This  function   is   not   guaranteed   to   be
21       IEEE-1180-compliant.  The  output of the IDCT routine is the difference
22       between the current block and the reference block. The difference pixel
23       can  occupy  nine bits and is represented as a 16-bit datum. The output
24       must be added to the motion-compensated reference  block  in  order  to
25       reconstruct the current block.
26

PARAMETERS

28       The function takes the following arguments:
29
30       block     Pointer to the current block. block must be 8-byte aligned.
31
32
33       coeffs    Pointer to the source DCT coefficients. coeffs must be 8-byte
34                 aligned.

36

RETURN VALUES

38       The function returns MLIB_SUCCESS if successful. Otherwise  it  returns
39       MLIB_FAILURE.
