NAME

       GStreamer::Event -  Structure describing events that are passed up and down a pipeline

DESCRIPTION

       The various event types are represented as subclasses:

       GStreamer::Event::FlushStart
       GStreamer::Event::FlushStop
       GStreamer::Event::EOS
       GStreamer::Event::NewSegment
       GStreamer::Event::Tag
       GStreamer::Event::BufferSize
       GStreamer::Event::QOS
       GStreamer::Event::Seek
       GStreamer::Event::Navigation
       GStreamer::Event::Custom::UP
       GStreamer::Event::Custom::DS
       GStreamer::Event::Custom::DS::OOB
       GStreamer::Event::Custom::Both
       GStreamer::Event::Custom::Both::OOB

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

       To check if an event is of a certain type, use the type method:

	 if ($event -> type eq "newsegment") {
	   # ...
	 }

	 elsif ($event -> type eq "eos") {
	   # ...
	 }

       To get to the content of an event, call the corresponding accessor:

	 if ($event -> type eq "newsegment") {
	   my $update = $event -> update;
	   my $rate = $event -> rate;
	   my $format = $event -> format;
	   my $start_value = $event -> start_value;
	   my $stop_value = $event -> stop_value;
	   my $stream_time = $event -> stream_time;

	   # ...
	 }

	 elsif ($event -> type eq "tag") {
	   my $tag = $event -> tag;

	   # ...
	 }
