I need to write a cross platform mobile app (Android and iOS) which does some image processing. I cannot use EmguCV because I don't have the license for it. The goal of the project is to basically "process a video stream" (an example would be OpenCV Face Detection). I need to be able to have a "callback" - like method on the CameraView which gets the current image frame as a parameter. These frames must be processed, if need be modified and finally displayed. I'm currently using Android's CvCameraViewListener, but this is platform specific and I won't be able to use this with the iOS project. Is there a Xamarin.Forms CameraView available which gives me similar functionality to the CvCameraViewListener inteface? Thanks!
