17 The mlib_VideoIDCT8x8_U8_S16() function computes the inverse DCT
18 (called IDCT) for the destination IDCT block of data type mlib_u8 and
19 source DCT coefficients of data type mlib_s16.
20
21
22 The stride applies to the block that is part of the frame currently
23 being reconstructed.
24
26 The function takes the following arguments:
27
28 block Pointer to an 8x8 block in the current frame. block must be
29 8-byte aligned.
30
31
32 coeffs Pointer to the source DCT coefficients. coeffs must be 8-byte
33 aligned.
34
35
36 stride Stride, in bytes, between adjacent rows in a block. stride
37 must be a multiple of eight.
38
39
41 The function returns MLIB_SUCCESS if successful. Otherwise it returns
42 MLIB_FAILURE.
