> Subject: [PATCH 4/4] dnn: add a new interface DNNModel.get_output
> 
> for some cases (for example, super resolution), the DNN model changes the
> frame size which impacts the filter behavior, so the filter needs to know the out
> frame size at very beginning.
> 
> Currently, the filter reuses DNNModule.execute_model to query the out frame
> size, it is not clear from interface perspective, so add a new explict interface
> DNNModel.get_output for such query.
