title: Camera 2 : Unable to record video in full screen?
body: <p>I'm using google official <a href="https://github.com/googlesamples/android-Camera2Video/blob/master/Application/src/main/java/com/example/android/camera2video/Camera2VideoFragment.java" rel="nofollow noreferrer">sample</a> to work around video recording by using Camera API 2 . but the problem is I'm not able to make it full screen as I limited the screen orientation only to portrait.Here the xml I edited and the <a href="https://github.com/googlesamples/android-Camera2Video/blob/master/Application/src/main/res/layout/fragment_camera2_video.xml" rel="nofollow noreferrer">official xml</a>.  </p>
  
  <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
  &lt;RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
      android:layout_width="match_parent"
      android:layout_height="match_parent"&gt;
  
      &lt;AutoFitTextureView
          android:id="@+id/texture"
          android:layout_width="wrap_content"

      &lt;/FrameLayout&gt;
  
  &lt;/RelativeLayout&gt;

  <p>I think here is setting the video screen size by aspect ration to the <code>TextureView</code> but I couldn't make it to full screen. Any help is greatly appreciated.</p>
  
  <pre><code>mVideoSize = chooseVideoSize(map.getOutputSizes(MediaRecorder.class));
  mPreviewSize = chooseOptimalSize(map.getOutputSizes(SurfaceTexture.class), width, height, mVideoSize);
  int orientation = getResources().getConfiguration().orientation;
  if (orientation == Configuration.ORIENTATION_LANDSCAPE) {
      mTextureView.setAspectRatio(mPreviewSize.getWidth(), mPreviewSize.getHeight());
  } else {
      mTextureView.setAspectRatio(mPreviewSize.getHeight(), mPreviewSize.getWidth());
  }
  </code></pre>
