Yes, currently I do cropping right if there is no scaling. Doing this with S_CROP is really ackward, but very few m2m driver has been ported to G_SELECTION yet. The v4l2transform was tested to run with Exynos 4 FIMC driver. There was still issue with such driver doing middle rounding for alignment. This has been reported on this list. The proposed solution is to add flags to our internal alignment method, and update these driver to pick a direction.
