title: How to display avi video with gstreamer?
body: <p>I want to write an object tracking program which needs to play the tracked result. As gstreamer is a good multimedia frame work, I want to use it in my demo program. But I don't know how to implement video display in detail. Can any one help?</p>
  
  <p>Avidemux plugin could separate the audio and video part from an avi file, but what to do next?</p>
  
  <p>If I open an uncompressed avi file, does it work if I directly link the output pad of avidemux plugin to a video sink?</p>
  
  <p>By the way, which video sink is better at the efficiency aspect?
  I looked up the plugin reference and found a lot of video sinks: glimagesink, osxvideosink, sdlvideosink, ximagesink, xvimagesink, dfbvideosink, fbdevsink, gconfvideosink
  Does autovideosink always work well? My platform is ubuntu 9.04.</p>
  
  <p>TIA~</p>
