title: Increasing brightness of ExoPlayer 2 just like MxPlayer
body: <p>I went through the entire documentation of <code>ExoPlayer2</code>, but couldn't find how to increase the brightness of <code>exoplayer</code>. I found a similar question </p>
  
  <p><a href="https://github.com/google/ExoPlayer/issues/2450" rel="noreferrer">on github</a></p>
  
  <p>My xml is as follows </p>
  
  <pre><code>&lt;com.google.android.exoplayer2.ui.PlayerView
          android:id="@+id/exoplayer_view_activity_exo_player"
          android:layout_width="0dp"
          android:layout_height="0dp"
          android:focusable="true"
          app:layout_constraintBottom_toBottomOf="parent"
          app:layout_constraintEnd_toEndOf="parent"
          app:layout_constraintStart_toStartOf="parent"
          app:layout_constraintTop_toTopOf="parent"
          app:resize_mode="fill"
          app:show_timeout="0"
          app:use_controller="true" /&gt;
  </code></pre>
  
  <p>If I use SurfaceView instead how I am going to use the methods of <code>exoplayer</code>. I tried placing my exoplayer tag in surface view tag but my app crashed. Is there any other way to increase brightness of <code>exoplayer</code>. Please don't paste code to increase system brightness.</p>
