How to integrate this in iOS. Does the model supports only images in nv21 image format?

I tried integrating it in iOS project using Objective C++ wrapper and NCNN. I was able to load the model and param files of both the model. I feed 80x80 image as ncnn::Mat to the model the confidence values are wrong. iOS does not directly support nv21 so I tried converting to it manually but now the model gives NaN as confidence
