NAME

GStreamer::Caps

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
