DESCRIPTION

22       The mlib_VideoDCT8x8_S16_S16_B10() function computes  the  forward  DCT
23       for the destination DCT coefficients of data type mlib_s16 and a source
24       block of data type mlib_s16. The input to the DCT routine is  the  dif‐
25       ference  between the current block and the reference block. The differ‐
26       ence pixel can occupy nine bits and is represented as a 16-bit datum.
27
28
29       The source and destination buffer addresses must be 8-byte aligned.

31
32       Since mediaLib 2.5,  mlib_VideoDCT8x8_S16_S16()  has  been  renamed  to
33       mlib_VideoDCT8x8_S16_S16_B10().  Now  mlib_VideoDCT8x8_S16_S16()  is an
34       alias of mlib_VideoDCT8x8_S16_S16_B10().

PARAMETERS

37       The function takes the following arguments:
38
39       coeffs    Pointer to the destination DCT coefficients. coeffs  must  be
40                 8-byte aligned.
41
42
43       block     Pointer  to  an 8x8 motion-compensated block that is the dif‐
44                 ference between the reference block and  the  current  block.
45                 block must be 8-byte aligned.

47

RETURN VALUES

49       The  function  returns MLIB_SUCCESS if successful. Otherwise it returns
50       MLIB_FAILURE.
