DESCRIPTION

17       The  mlib_VideoColorBGR2JFIFYCC422() function performs color space con‐
18       version from BGR to YCbCr together with sampling rate  conversion  when
19       used in the JPEG File Interchange Format (JFIF).

PARAMETERS

22       The function takes the following arguments:
23
24       y      Pointer  to  destination  Y  component  row.  y  must  be 8-byte
25              aligned.
26
27
28       cb     Pointer to destination Cb  component  row.  cb  must  be  8-byte
29              aligned.
30
31
32       cr     Pointer  to  destination  Cr  component  row.  cr must be 8-byte
33              aligned.
34
35
36       bgr    Pointer to source BGR multi-component row. bgr  must  be  8-byte
37              aligned.
38
39
40       n      Length  of Y component row. n must be even. The length of Cb and
41              Cr component rows must be n/2. The length of the BGR  multi-com‐
42              ponent row must be 3*n.
