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 ENUMS AND FLAGS
flags GStreamer::MessageType o 'unknown' / 'GST_MESSAGE_UNKNOWN' o 'eos' / 'GST_MESSAGE_EOS' o 'error' / 'GST_MESSAGE_ERROR' o 'warning' / 'GST_MESSAGE_WARNING' o 'info' / 'GST_MESSAGE_INFO' o 'tag' / 'GST_MESSAGE_TAG' o 'buffering' / 'GST_MESSAGE_BUFFERING' o 'state-changed' / 'GST_MESSAGE_STATE_CHANGED' o 'state-dirty' / 'GST_MESSAGE_STATE_DIRTY' o 'step-done' / 'GST_MESSAGE_STEP_DONE' o 'clock-provide' / 'GST_MESSAGE_CLOCK_PROVIDE' o 'clock-lost' / 'GST_MESSAGE_CLOCK_LOST' o 'new-clock' / 'GST_MESSAGE_NEW_CLOCK' o 'structure-change' / 'GST_MESSAGE_STRUCTURE_CHANGE' o 'stream-status' / 'GST_MESSAGE_STREAM_STATUS' o 'application' / 'GST_MESSAGE_APPLICATION' o 'element' / 'GST_MESSAGE_ELEMENT' o 'segment-start' / 'GST_MESSAGE_SEGMENT_START' o 'segment-done' / 'GST_MESSAGE_SEGMENT_DONE' o 'duration' / 'GST_MESSAGE_DURATION' o 'latency' / 'GST_MESSAGE_LATENCY' o 'async-start' / 'GST_MESSAGE_ASYNC_START' o 'async-done' / 'GST_MESSAGE_ASYNC_DONE' o 'request-state' / 'GST_MESSAGE_REQUEST_STATE' o 'step-start' / 'GST_MESSAGE_STEP_START' o 'qos' / 'GST_MESSAGE_QOS' o 'progress' / 'GST_MESSAGE_PROGRESS' o 'any' / 'GST_MESSAGE_ANY' SEE ALSO
