    Hi Qiyang,
    could you please show your project message with me through my email address steven-shi@ti.com? such as processor interfaced with UB964? application?...
    for your questions, please check:
    Q1：Video colors are all green。
    A: it seems the processor can NOT recover the correct raw data from "camera + UB964". Please check the camera sensor output spec. and UB964's register 0x73~0x76?

    Q2：Obviously used port0, but there have been four pictures
    A: the issue could be from the processor output format setting (which is connected with UB964). For UB964, you can only forward RX0 input to the CSI port.

    Q3：When I move the camera, the screen conversion is very slow, 10 seconds after the change
    A: the video display source is from the processor, so please check the processor output setting. thanks.

    best regards,.
    Steven
