title: How do I set default decoder to playbin2?
body: <p>I'm trying to receive video stream, which is now mjpeg stream. In order to make program independent of broadcast protocol and video stream format I'm using playbin2. It works, but it takes a lot of time for playbin to connect to stream. I guess the problem is decoder, because when I tested:</p>
  
  <pre><code>gst-launch-0.10 soupthhpsrc location=http://some_location timeout 5 ! jpegdec ! autoaudiosink
  </code></pre>
  
  <p>and it works just fine. Connection takes something like 1 second. 
  So the question is : Is there any way to set jpegdec as default decoder for my playbin?</p>
