did you use adv7180? if yes, I think you should use mxc_v4l2_tvin.out.

and I'm not sure what mode do you use, one can refer this thread too.

Hi Joan,

     thanks your reply, i modify the cam->crop_current.top, and call ioctl VIDIOC_G_STD , now I can get the initial value of cam->crop_current.top , and cam->crop_current.top is set value, the display keep scrolling down slower, how can i solve it ? thanks.
