title: OpenCV 4.1 native Videocapture on Android
body: <p>OpenCV 4.1 <a href="https://opencv.org/opencv-4-1/" rel="nofollow noreferrer">release notes</a> state that <em>Android Media NDK API support has been added to videoio module</em>.</p>
  
  <p>However, i still fail to open the camera on an Android smartphone using Videocapture.open(). I know that in the past, the Android NDK did not provide a native camera interface (changed in Android 7.0 Nougat / API level 24) and cv::Videocapture was therefore not supported on Android prior to OpenCV 4.1.
  Unfortunately, i could not find detailed patch notes on what exactly was added in the 4.1 release.</p>
  
  <p>I use OpenCV as a .so library / plugin within Unity3D, which handles the camera permissions (tested - permission is granted).</p>
  
  <p>Has anyone had success with this and can point me in the right direction?</p>
