NAME
mlib_VideoDCT2x2_S16_S16 - forward Discrete Cosine Transform (DCT)
SYNOPSIS
cc [ flag... ] file... -lmlib [ library... ] #include <mlib.h> mlib_status mlib_VideoDCT2x2_S16_S16(mlib_s16 coeffs[4], const mlib_s16 block[4]);
DESCRIPTION
The mlib_VideoDCT2x2_S16_S16() function computes the forward DCT for the destination DCT coefficients of data type mlib_s16 and a source block of data type mlib_s16. The input to the DCT routine is the difference between the current block and the reference block. The differ- ence pixel can occupy nine bits and is represented as a 16-bit datum. The source and destination buffer addresses must be 8-byte aligned.
PARAMETERS
The function takes the following arguments: coeffs Pointer to the destination DCT coefficients. coeffs must be 8-byte aligned. block Pointer to an 2x2 motion-compensated block that is the difference between the reference block and the current block. block must be 8-byte aligned.
RETURN VALUES
The function returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE.
