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

=head1 DESCRIPTION
The various nmessage types are represented as subclasses:
=over
=item GStreamer::Message::EOS
=item GStreamer::Message::Error
=item GStreamer::Message::Warning
=item GStreamer::Message::Info
=item GStreamer::Message::Tag
=item GStreamer::Message::Buffering
=item GStreamer::Message::StateChanged
=item GStreamer::Message::StateDirty
=item GStreamer::Message::StepDone
=item GStreamer::Message::ClockProvide
=item GStreamer::Message::ClockLost
=item GStreamer::Message::NewClock
=item GStreamer::Message::StructureChange
=item GStreamer::Message::StreamStatus
=item GStreamer::Message::Application
=item GStreamer::Message::Element
=item GStreamer::Message::SegmentStart
=item GStreamer::Message::SegmentDone
=item GStreamer::Message::Duration
=item GStreamer::Message::Latency [0.10.12]
=item GStreamer::Message::AsyncStart [0.10.13]
=item GStreamer::Message::AsyncDone [0.10.13]
=back
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 I<&> operator on the
I<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;
# ...
}
