Hi Laurent, Thank you for your fast answer.

I have seen, that the resizer "only" supports downscaling by 0.25, so with all the cropping, 1944 lines will come down to 482 which is too big for my framebuffer. If I apply some cropping in the omap3_isp_viewfinder_setup function, the output will work as expected. Now I'm going to crop on the sensor (or better on the first entity that supports cropping, as in your code) if the ratio "sensor input -> viewfinder output" exceeds 0.25. Are you interested in a patch for this?
