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;
# ...
}

structure = $event-> get_structure¶
