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. ATTRIBUTES

The mlib_VideoDCT8x8_S16_U8_NA() function computes the forward DCT for the destination DCT coefficients of data type mlib_s16 and source block of data type mlib_u8. The stride applies to the block that is part of the frame currently being encoded. 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 destination DCT coefficients. block Pointer to an 8x8 block in the current frame. stride Stride in bytes between adjacent rows in the block. RETURN VALUES
The function returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE. ATTRIBUTES
