CSI IPU crop

I'm trying to implement digital zoom of camera image using cropping by IPU. This seems to be already implemented by current BSP (running 3.0.35 kernel) with V4L2 command VIDIOC_S_CROP. But when I try to use this the timings(?) gets wrong with the result that preview stream is showing the same image multiple times but smaller (eg. image is shown 4*2 times when crop set to half width/height) while slowly scrolling.


Has anyone here had any luck with using IPU to implement digital zoom?
