title: gst-launch command to play a video using vaapi hardware acceleration
body: <p>I need two gst-launch-1.0 command lines</p>
  
  <p>1) The first one is simple to play a video (.mp4) without using any hardware acceleration.</p>
  
  <p>2) The sencond one is to play the video (.mp4) using hardware acceleration, I am using Intel HD graphics with the i965 driver.</p>
  
  <p>I already installed the gstreamer plugins.</p>
  
  <p>Any help would be appreciated.</p>
