title: Rotating or scaling cameraView or opponentView in Quickblox isn't working on Android
body: <p>When trying to rotate or scale the cameraView or the opponentView in the <a href="http://quickblox.com/developers/Sample-videochat-android" rel="nofollow">Sample-videochat-android</a> I get a black view instead.
  I tried</p>
  
  <pre><code>android:rotation="90"
  </code></pre>
  
  <p>And I also tried flipping the view using</p>
  
  <pre><code>android:scaleX="-1"
  </code></pre>
  
  <p>None of the above methods is working. Any suggestions?</p>
