Would like to bring this back up. I'd like to merge this, as specially the scaling is freely done by the video asic, offering a possibility to scale without requiring non-free libnpp. And cropping so far is not possible at all. Yes, scaling and cropping is not something a decoder usually does, but it exposes a hardware feature that has no other way of accessing it, which offers valuable functionality to users.
