SYNOPSIS

   use GStreamer::Interfaces;
 
   # GStreamer::PropertyProbe
 
   my $sink = GStreamer::ElementFactory -> make(alsasink => "sink");
   my $pspec = $sink -> get_probe_property("device");
 
   if ($sink -> needs_probe($pspec)) {
     $sink -> probe_property($pspec);
   }
 
   my @devices = $sink -> get_probe_values($pspec);
 
   # GStreamer::XOverlay
 
   my $overlay = GStreamer::ElementFactory -> make(xvimagesink => "overlay");
   $overlay -> set_xwindow_id($xid);

values = $element->probe_get_probe_values (pspec)
bool = $element->needs_probe_name (name)
$element->probe_property_name (name)
values = $element->get_probe_values_name (name)
values = $element->probe_get_probe_values_name (name)
