NAME
       mlib_VideoIDCT8x8_S16_S16_DC - inverse Discrete Cosine Transform

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

       mlib_status mlib_VideoIDCT8x8_S16_S16_DC(mlib_s16 *block,
	    const mlib_s16 *coeffs);

DESCRIPTION
       The mlib_VideoIDCT8x8_S16_S16_DC() function can be used only when F(0,0) is nonzero. It computes the inverse DCT (called IDCT) for the out-
       put IDCT block of data type mlib_s16 and input DCT coefficients of data type mlib_s16. This function is not guaranteed to be IEEE-1180-com-
       pliant. The output of the IDCT routine is the difference between the current block and the reference block. The difference pixel can occupy
       nine bits and is represented as a 16-bit datum. The output must be added to the motion-compensated reference block in order to  reconstruct
       the current block.

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.

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