NAME
       mlib_VideoDeQuantizeIDCT8x8_S16_S16_B12_NA - dequantization and inverse Discrete Cosine Transform (IDCT)

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

       mlib_status mlib_VideoDeQuantizeIDCT8x8_S16_S16_B12_NA(
	    mlib_s16 block[64], const mlib_s16 coeffs[64],
	    const mlib_d64 dqtable[64]);

DESCRIPTION
       The  mlib_VideoDeQuantizeIDCT8x8_S16_S16_B12_NA()  function  dequantizes  the quantized DCT coefficients and then computes the inverse DCT.
       It's a combination of mlib_VideoDeQuantize_S16() and mlib_VideoIDCT8x8_S16_S16_B12_NA() for better performance. The output of this function
       should  be  within  the range of [-2048, 2047] if coeffs is obtained from the corresponding mlib_VideoDCT8x8Quantize_S16_S16_B12_NA() func-
       tion.

       This function requires no special address alignment.

       This function can be used in JPEG with 12-bit precision, or in MPEG for the inter 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().

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