Name

mlib_VideoDCT16x16_S16_S16_B10 - forward Discrete Cosine Transform (DCT)

Synopsis

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

mlib_status mlib_VideoDCT16x16_S16_S16_B10(mlib_s16 coeffs[256],
     const mlib_s16 block[256]);

Description

The mlib_VideoDCT16x16_S16_S16_B10() function computes the forward DCT for the destination DCT coefficients of data type mlib_s16 and 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 difference pixel which can occupy 10 bits, is represented as a 16-bit data.

Parameters

The function takes the following arguments:

coeffs

Pointer to the output DCT coefficients. Note that coeffs must be 8-byte aligned.

block

Pointer to a 16x16 motion-compensated block which is the difference between the reference block and the current block. Note that block must be 8-byte aligned.

Return Values

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