title: gstremer plugin ffdec_h264 is missing after installing gst-libav package codebase
body: <p>My system is Ubuntu 15.04 64 bit.</p>
  
  <p>I have downloaded <a href="https://gstreamer.freedesktop.org/src/gst-libav/gst-libav-1.8.3.tar.xz" rel="nofollow">https://gstreamer.freedesktop.org/src/gst-libav/gst-libav-1.8.3.tar.xz</a> 
  and performed below steps.</p>
  
  <pre><code>./configure --prefix=/usr
  make
  sudo make install
  </code></pre>
  
  <p>every thing looks fine.</p>
  
  <p>Now when i check </p>
  
  <pre><code>gst-inspect-1.0 ffdec_h264
  No such element or plugin 'ffdec_h264'
  </code></pre>
  
  <p>I understand that ffdec_h264 gstreamer plugin is part of <strong>gst-libav-1.8.3.tar.xz</strong> and after installing that i do not get that plugin.</p>
  
  <p>what steps i am missing. </p>
