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);
