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);
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.
The function takes the following arguments:
block
coeffs
stride
The function returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE.
