NAME
       mlib_VideoDeQuantizeIDCT8x8_U8_S16_NA - dequantization and inverse Dis‐
       crete Cosine Transform (IDCT)

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

       mlib_status mlib_VideoDeQuantizeIDCT8x8_U8_S16_NA(
	   mlib_u8 *block, const mlib_s16 coeffs[64],
	   const mlib_d64 dqtable[64], mlib_s32 stride);

DESCRIPTION
       The mlib_VideoDeQuantizeIDCT8x8_U8_S16_NA()  function  dequantizes  the
       quantized  DCT  coefficients and then computes the inverse DCT.	It's a
       combination	   of	       mlib_VideoDeQuantize_S16()	   and
       mlib_VideoIDCT8x8_U8_S16_NA() for better performance.

       This function requires no special address alignment.

       This  function can be used in JPEG with 8-bit precision, or in MPEG for
       the intra mode.

PARAMETERS
       The function takes the following arguments:

       block	  Pointer to an 8x8 block.

       coeffs	  Pointer to the input quantized DCT coefficients.

       dqtable	  Pointer   to	 the   dequantization	table	generated   by
		  mlib_VideoDeQuantizeInit_S16().

       stride	  Stride in bytes between adjacent rows in the block.

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