NAME
mlib_VideoDCT8x8_S16_U8 - forward Discrete Cosine Transform (DCT)
SYNOPSIS
cc [ flag... ] file... -lmlib [ library... ] #include <mlib.h> mlib_status mlib_VideoDCT8x8_S16_U8(mlib_s16 coeffs[64], const mlib_u8 *block, mlib_s32 stride);
DESCRIPTION
The mlib_VideoDCT8x8_S16_U8() function computes the forward DCT for the destination DCT coefficients of data type mlib_s16 and source block of data type mlib_u8. The input to the DCT routine is the difference between the current block and the reference block. The difference pixel can occupy nine bits and is represented as a 16-bit datum. In the case of an mlib_s16 source data type and an mlib_u8 output data type, the stride applies to the block that is part of the frame currently being encoded.
PARAMETERS
The function takes the following arguments: coeffs Pointer to the destination DCT coefficients. coeffs must be 8-byte aligned. block Pointer to an 8x8 block in the current frame. block must be 8-byte aligned. stride Stride in bytes between adjacent rows in a block. stride must be a multiple of eight.
RETURN VALUES
The function returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE.
