Y : wanted Main burst length = 2 * Yburst1_Pr, and wanted Remained burst length = 2 * Yburst2_Pr.
Cb/Cr : wanted Main burst length = Yburst1_Pr / 2 = Cburst1_Pr,
and wanted Remained burst length = Yburst2_Pr / 2 = Cburst2_Pr
If Rot90_Pr = 0, no rotation, the wanted burst length is calculated from targetHsize.
If Rot90_Pr = 1, rotate90',
When Preview output is InterleaveYCbCr422 and OutRot90_Pr = 1, wanted burst length must be 4.
When Preview output is RGB565 and OutRot90_Pr = 1, wanted burst length must be ≤ 4.
When Preview output is Non-Interleave YCbCr and OutRot90_Pr = 1, wanted burst length must be 2(Y) and 1(C).
If Preview output is RGB888/666 mode and OutRot90_Pr = 1, and the original target horizontal width size before
rotation(TargetHsize) is lager than 160 pixels, wanted burst length must be ≤ 4. But, the original target horizontal
width size before rotation(TargetHsize) is smaller than 160 pixels, wanted burst length must be ≤ 8.
If Preview output is YCbCr mode (Non-interleave + Interleave) and OutRot90_Pr = 1, the original target horizontal
width size before rotation(TargetHsize) must be smaller than 160 pixels and TargetVsize must be 8's multiple.

aution! Preview path contains 320 pixel line buffer for rotation. Therefore, upper 640 pixels, input images must
be pre-scaled by over 1/2 for capturing valid preview image.
