NAME
mlib_VideoDeQuantizeIDCT8x8_U8_S16_NA - dequantization and inverse Discrete 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.
