NAME
       mlib_VideoDCT8x8Quantize_S16_U8_NA - forward Discrete Cosine Transform (DCT) and quantization

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

       mlib_status mlib_VideoDCT8x8Quantize_S16_U8_NA(
	    mlib_s16 coeffs[64], const mlib_u8 *block,
	    const mlib_d64 dqtable[64], mlib_s32 stride);

DESCRIPTION
       The  mlib_VideoDCT8x8Quantize_S16_U8_NA()  function computes the forward DCT and then quantizes the DCT coefficients. It's a combination of
       mlib_VideoDCT8x8_S16_U8_NA() and mlib_VideoQuantize_S16() 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:

       coeffs	  Pointer to the quantized DCT coefficients.

       block	  Pointer to an 8x8 block.

       dqtable	  Pointer to the quantization table generated by mlib_VideoQuantizeInit_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.
