The isp pipeline problem of reVISION filter2d example

When i use the ZCU104 to test the reVISION GET START EXAMPLE filter2d.

The output video is too green .So i want to modifly the pipeline isp by follow step

root@xilinx:~# yavta --no-query -l /dev/v4l-subdev4
Device /dev/v4l-subdev4 opened.

But it doesn't work  . I also change the brightness parameter, it doesn't work ,too.The output of the video is still very green.

Do i use the incorrect way to modify the parameter ? Is there any other way to change the preset of pipeline .

Thanks,

Jasper
