DESCRIPTION

The various query types are represented as subclasses:

GStreamer::Query::Position

GStreamer::Query::Duration

GStreamer::Query::Latency

GStreamer::Query::Jitter

GStreamer::Query::Rate

GStreamer::Query::Seeking

GStreamer::Query::Segment

GStreamer::Query::Convert

GStreamer::Query::Formats

To create a new query, you call the constructor of the corresponding class.

To modify or retrieve the content of a query, call the corresponding mutator:

my $query = GStreamer::Query::Position -> new("time");
$query -> position("time", 23);
my ($format, $position) = $query -> position;

my $query = GStreamer::Query::Duration -> new("time");
$query -> duration("time", 23);
my ($format, $duration) = $query -> duration;
