NAME

GStreamer::Message

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

uint64 = $message->timestamp

messagetype = $message->type
