title: Gstreamer support for Qt5 on Raspberry Pi
body: <p>I need to play audio from my Qt project deployed on Raspberry Pi. Everything works fine except that I don't get any audio out, instead I get the following error message</p>
  
  <pre><code>defaultServiceProvider::requestService(): no service found for - "org.qt-project.qt.mediaplayer"
  </code></pre>
  
  <p>After googling around I have come to the conclusion that the problem is that Gstreamer is not installed and recognized by Qt (more precisely gst-omx). Also, I have tried for many days to proper install gst-omx on Raspberry Pi without much luck.
  Can anyone guide me to how I solve this issue???</p>
  
  <p>One hack would of course just to use an external application to play the audio like mpeg321 and just start it up by QProcess, but I need to control volume and be able to start, stop, and pause, so such a solution is not really feasible...</p>
