Helllo, I'm currently developing an app which need to record video in background and process it.

(Control Android device using real-time image processing)

However, to achieve it, I need to use Camera and OpenCV as Service, and it seems that it is impossible to use JavaCamera and Android.Hardware.Camera without using any preview.

Here are my questions.

1. I heard that NativeCamera can be used for this purpose. Is it possible? (Possibly with examples?)

2. Is there any method that I can use JavaCameraView(or similar stuff) for this purpose? I currently use Galaxy S4.

Thank you for answering the question.
