title: GStreamer installation is missing a plug-in
body: <p>I hope that someone can help with this problem, been searching for a solution for the past 2 days.</p>
  
  <p>To describe the problem in short: I'm trying to make a simple qt5.7 application that will stream an m3u8 (using Qt Creator (community). But when I try to run it I get a </p>
  
  <pre><code>Warning: "No decoder available for type 'application/x-hls'."
  Error: "Your GStreamer installation is missing a plug-in."
  </code></pre>
  
  <p>"gst-inspect | grep hls"
  returns: typefindfunctions: application/x-hls: m3u8</p>
  
  <p>At this point I have no idea which plugin can I even miss as I have gone trough the complete GStreamer plugin list and put one after another.
  As far as my search went some got the fix by installing the bad/ugly plugins. Some say that the QT5 still uses gstreamer0.10, but new linux versions use the 1.0 (lost at this point). I tried to set a flag to force the GST_VERSION=1.0, did not work, or I did something wrong (I used the qmake GST_VERSION=1.0 command). Also, I am able to play the video in vlc.
  I am completely stuck, and don't know what to do anymore.</p>
  
  <p>the app code: </p>
  
  <pre><code>import QtQuick 2.7
  import QtQuick.Window 2.2
  import QtMultimedia 5.7
  
  Window {
      visible: true

          }
