DESCRIPTION

20       The  mlib_VideoColorYUV2ABGR420_W()  function performs YUV to RGB color
21       conversion used in MPEG1 and  MPEG2  video  compression  in  the  4:2:0
22       sequence. It performs color conversion together with window clipping.
23
24
25       The  luminance component is stored in Y, the chrominance components are
26       stored in U and V, respectively. The  size  of  the  chrominance  image
27       depends  on  the  chroma format used by the sequence. In this sequence,
28       the chrominance components are subsampled 2-to-1 in both the horizontal
29       and vertical directions in respect to the luminance component.

PARAMETERS

32       The function takes the following arguments:
33
34       abgr           Pointer  to the destination packed ABGR image. abgr must
35                      be 8-byte aligned.
36
37
38       y              Pointer to the source Y  component.  y  must  be  8-byte
39                      aligned.
40
41
42       u              Pointer  to  the  source  U  component. u must be 4-byte
43                      aligned.
44
45
46       v              Pointer to the source V  component.  v  must  be  4-byte
47                      aligned.
48
49
50       width          Width of the image. width must be a multiple of 8.
51
52
53       height         Height of the image. height must be a multiple of 2.
54
55
56       abgr_stride    Stride,  in  bytes,  between  adjacent  rows in the ABGR
57                      image. abgr_stride must be a multiple of 8.
58
59
60       y_stride       Stride, in bytes, between adjacent rows in the Y  compo‐
61                      nent image. y_stride must be a multiple of 8.
62
63
64       uv_stride      Stride,  in  bytes, between adjacent rows in the U and V
65                      component images. uv_stride must be a multiple of 8.
66
67
68       left           Left border of clipping window.  0  ≤  left  <  right  ≤
69                      width.
70
71
72       top            Top  border  of  clipping  window.  0  ≤  top < bottom ≤
73                      height.
74
75
76       right          Left border of clipping window.  0  ≤  left  <  right  ≤
77                      width.
78
79
80       bottom         Bottom  border  of  clipping  window. 0 ≤ top < bottom ≤
81                      height.
