17 The input to the DCT routine is the difference between the current
18 block and the reference block. The difference pixel can occupy nine
19 bits and is represented as a 16-bit datum. The source and destination
20 buffer addresses must be 8-byte aligned.
21
23 The function takes the following arguments:
24
25 coeffs Pointer to the destination DCT coefficients. coeffs must be
26 8-byte aligned.
27
28
29 block Pointer to an 16x16 motion-compensated block that is the dif‐
30 ference between the reference block and the current block.
31 block must be 8-byte aligned.

33
35 The function returns MLIB_SUCCESS if successful. Otherwise it returns
36 MLIB_FAILURE.
