In practice it makes no difference i guess, since the actual AVCodecContext fields are all int anyway, but maybe it could be reflected here. I'm not sure if the difference between AV_OPT_TYPE_BOOL and AV_OPT_TYPE_INT has any implications for API users, though. > +Enable cropping if cropping parameters are a multiply of the required > +alignment for the left and top parameters.
