mlib_VideoIDCT8x8_U8_S16 - inverse Discrete Cosine Transform SYNOPSIS
cc [ flag... ] file... -lmlib [ library... ] #include <mlib.h> mlib_status mlib_VideoIDCT8x8_U8_S16(mlib_u8 *block, const mlib_s16 coeffs[64], mlib_s32 stride); DESCRIPTION
The mlib_VideoIDCT8x8_U8_S16() function computes the inverse DCT (called IDCT) for the destination IDCT block of data type mlib_u8 and source DCT coefficients of data type mlib_s16. The stride applies to the block that is part of the frame currently being reconstructed. PARAMETERS
The function takes the following arguments: block Pointer to an 8x8 block in the current frame. block must be 8-byte aligned. coeffs Pointer to the source DCT coefficients. coeffs 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. ATTRIBUTES
