                  In Pitivi we'd like to hide the GL effects when the
                  system has no GL component. A quick inspection
                  (gst-inspect-1.0 | grep -i gl) shows these effects are
                  provided by the "opengl" plugin, so for now we only
                  care about the "opengl" plugin from gst-plugins-bad.<br>
                  <br>
                  How can we programmatically figure out beforehand
                  whether these effects can be used?<br>
