21 The mlib_VideoColorJFIFYCC2RGB420() function performs color space con‐
22 version from YCbCr to RGB together with sampling rate conversion when
23 used in the JPEG File Interchange Format (JFIF).
24
26 The function takes the following arguments:
27
28 rgb0 Pointer to upper destination RGB multi-component row. rgb0 must
29 be 8-byte aligned.
30
31
32 rgb1 Pointer to lower destination RGB multi-component row. rgb1 must
33 be 8-byte aligned.
34
35
36 y0 Pointer to upper destination Y component row. y0 must be 8-byte
37 aligned.
38
39
40 y1 Pointer to lower destination Y component row. y1 must be 8-byte
41 aligned.
42
43
44 cb0 Pointer to source upper Cb component row. cb0 must be 8-byte
45 aligned.
46
47
48 cr0 Pointer to source upper Cr component row. cr0 must be 8-byte
49 aligned.
50
51
52 cb1 Pointer to source middle Cb component row. cb1 must be 8-byte
53 aligned.
54
55
56 cr1 Pointer to source middle Cr component row. cr1 must be 8-byte
57 aligned.
58
59
60 cb2 Pointer to source lower Cb component row. cb2 must be 8-byte
61 aligned.
62
63
64 cr2 Pointer to source lower Cr component row. cr2 must be 8-byte
65 aligned.
66
67
68 n Length of Y component row. n must be even. The length of Cb and
69 Cr component rows must be n/2. The length of the RGB multi-com‐
70 ponent row must be 3*n.
71
72
74 The function returns MLIB_SUCCESS if successful. Otherwise it returns
75 MLIB_FAILURE.
