title: Android video remove chroma key background
body: <p>I have checked <a href="https://stackoverflow.com/questions/12813089/i-am-working-on-android-camera-app-i-want-to-capture-image-and-change-its-backgr">this</a> question.</p>
  
  <p>It is very similar: 
  I want to record a video with android camera.
  After that with a library remove the background, which is with chroma key. 
  First I think I should use android NDK in order to escape from SDK memory limitation and use the whole memory. 
  The length of the video is short, a few seconds so maybe is able to handle it. 
  I would prefer to use an SDK implementation and set the <code>android:largeHeap="true"</code> , because of mismatching the .so files architecture.</p>
  
  <p>Any library suggestion for SDK or NDK please.</p>
