NAME

       GStreamer::Caps -  Structure describing sets of media formats

SYNOPSIS

	 my $empty = GStreamer::Caps::Empty -> new();

	 my $any = GStreamer::Caps::Any -> new();

	 my $structure = {
	   name => "urgs",
	   fields => [
	     [field_one => "Glib::String" => "urgs"],
	     [field_two => "Glib::Int" => 23]
	   ]
	 };
	 my $full = GStreamer::Caps::Full -> new($structure);

	 my $simple = GStreamer::Caps::Simple -> new(
			"audio/mpeg",
			field_one => "Glib::String" => "urgs",
			field_two => "Glib::Int" => 23);

       GStreamer::Caps::Any->new
       GStreamer::Caps::Empty->new
       GStreamer::Caps::Full->new
       GStreamer::Caps::Simple->new
