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. The source and destination buffer addresses must be 8-byte aligned.
The function takes the following arguments:
coeffs
block
The function returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE.
