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);

DESCRIPTION

       To create a GStreamer::Caps object, you call one of the following constructors:

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