title: Using one MediaCapture in multiple CaptureElement.Source
body: <p>I'm trying to preview one MediaCapture to multiple(2) CaptureElement's. For example I have one big CaptureElement and one mini - map of it in the screen corner. Is it possible?</p>
  <p>When I'm trying to set initialized Capture to one CaptureElement, everything works fine, but when I share it in 2 places, I'm getting error like &quot;unsupported operation for current state&quot;.</p>
  <p>Here's the code example, I'm trying to use:</p>
  <pre><code>await video.TryStopPreviewingAsync();
  minimap.Source = null;
  await minimap.Dispatcher.RunAsync(CoreDispatcherPriority.Normal, () =&gt;
  {
      minimap.Source = video.Stream.Capture;
  });
  await video.TryStartPreviewingAsync();
  </code></pre>
  <p><code>minimap</code> is second CaptureElement,<code>video.Resources.First.Stream.Capture</code> is currently previewing capture.</p>
  <p><code>TryStop/StartPreviewingAsync</code>calls <code>Capture.Stop/StartPreviewingAsync()</code></p>
  <p>I tried to stop previewing first capture, set it like a source in 2 places and then starts previewing on both captureelements, but I got error.</p>
