title: tunnel playback using hardware decoder
body: <p>I tried the video playback through Exo-player. I have made changes in the exo-player code to support tunneling mode as suggested in the below link.</p>
  
  <p><a href="https://medium.com/google-exoplayer/tunneled-video-playback-in-exoplayer-84f084a8094d" rel="nofollow noreferrer">https://medium.com/google-exoplayer/tunneled-video-playback-in-exoplayer-84f084a8094d</a></p>
  
  <p>I have added hardware decoder support in the media_codec.xml file. I have also included the tunneling feature in the xml file as mentioned below.</p>
  
  <p>Feature name="tunneled-playback" required="true"/></p>
  
  <p>Once i enable the "tunneled-playback" feature, the player is making use of software video decoder.</p>
  
  <p>Even after all the changes, software decoder is being used.
  Can someone suggest me how to make use of hardware decoder with the tunneled-playback feature?</p>
