GStreamer::Event3pm
Structure describing events that are passed up and down a pipeline
Overview
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;# ...}
