title: Saved video as input instead of Camera in android
body: <p>I've implemented an android app that implements the CvCameraListener interface. In the onCameraFrame(Mat inputFrame) method I process the captured inputFrame from the camera. 
  Now to my problem: Is there a way that I can use a saved video file on my phone as an input instead of getting the frames directly from camera? That means I would like to have a video file input frame by frame in Mat format.</p>
  
  <p>Is there a possible way to do that?</p>
  
  <p>Thanks for your answers</p>
