Recording Live OpenCV Processing on Android

Question

My goal is to do a couple things:

1. Use OpenCV and the JavaCameraView to process frames from the phone\'s camera feed
2. Enable recording of that processed

Answer 1

Another option that works only on Lollipop and Marshmallow is to use the new MediaProjectionManager to capture and record what's happening on your device's screen. A great example is here:

It's totally independent of your device's camera and doesn't need any access to it or whatever you're doing with OpenCV. It's just recording whatever you have displayed on your screen.
