NAME

       GStreamer::Message -  Lightweight objects to signal the application of pipeline events

DESCRIPTION

       The various nmessage types are represented as subclasses:

       GStreamer::Message::EOS
       GStreamer::Message::Error
       GStreamer::Message::Warning
       GStreamer::Message::Info
       GStreamer::Message::Tag
       GStreamer::Message::Buffering
       GStreamer::Message::StateChanged
       GStreamer::Message::StateDirty
       GStreamer::Message::StepDone
       GStreamer::Message::ClockProvide
       GStreamer::Message::ClockLost
       GStreamer::Message::NewClock
       GStreamer::Message::StructureChange
       GStreamer::Message::StreamStatus
       GStreamer::Message::Application
       GStreamer::Message::Element
       GStreamer::Message::SegmentStart
       GStreamer::Message::SegmentDone
       GStreamer::Message::Duration
       GStreamer::Message::Latency [0.10.12]
       GStreamer::Message::AsyncStart [0.10.13]
       GStreamer::Message::AsyncDone [0.10.13]

       To create a new message, you call the constructor of the corresponding class.

       To check if a message is of a certain type, use the & operator on the type method:

	 if ($message -> type & "error") {
	   # ...
	 }

	 elsif ($message -> type & "eos") {
	   # ...
	 }

       To get to the content of a message, call the corresponding accessor:

	 if ($message -> type & "state-changed") {
	   my $old_state = $message -> old_state;
	   my $new_state = $message -> new_state;
	   my $pending = $message -> pending;

	   # ...
	 }

	 elsif ($message -> type & "segment-done") {
	   my $format = $message -> format;
	   my $position = $message -> position;

	   # ...
	 }

METHODS

   object = $message->src
   structure = $message->get_structure
   64 bit unsigned = $message->timestamp
   messagetype = $message->type
