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
