13       void mlib_VideoColorYUV444seq_to_YUYV422int(mlib_u32 *YUYV,
14            const mlib_u8 *Y, const mlib_u8 *U, const mlib_u8 *V, mlib_s32 w,

DESCRIPTION

19       The Y, U, V pixel streams are combined into a YUYV  pixel  stream.  All
20       pixel  components  are 8-bit unsigned integers. The Y, U, and V buffers
21       have dimensions w and h. Dimension w is assumed to be a multiple of  2.
22       Adjacent U and V values are averaged to get the output U and V values.
23
24
25       The following equation is used:
26
27         YUYV[r][c/2] = (Y[r][c]  << 24) |
28                        (((U[r][c] + U[r][c+1]) / 2) << 16) |
29                        (Y[r][c+1] << 8) |
30                        (((V[r][c] + V[r][c+1]) / 2))
31
32
33
34       where r = 0, 1, 2, ..., h-1; and c = 0, 2, 4, ..., w-2.
