GStreamer::Event(3pm)
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;# ...
- }
