/***************************************************************************************
这个主要是预览,通过scale3_msi将dvp/csi数据scale到对应的分辨率作为数据流发送出去
然后lcd_msi需要接收对应的数据去显示
这里只是产生对应数据流,数据用途实际需要终端流(比如lcd流)接收后去处理
----> R_VIDEO_P0(320x240)
| (lcd_video_p0)
S_PREVIEW_SCALE3 -----|
(scale3) |
----> R_VIDEO_P1(320x240)
(lcd_video_p1)
