mlib_status mlib_VideoDCT8x8_S16_S16_NA(mlib_s16 coeffs[64], const mlib_s16 block[64]);
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. This function requires no special address alignment.
The function takes the following arguments:
coeffs Pointer to the destination DCT coefficients.
block Pointer to an 8x8 motion-compensated block that is the difference between the reference block and the current block.
The function returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE.
