NAME

GStreamer::Query - Dynamically register new query types. Provide functions to create queries, and to set and parse values in them.

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;

METHODS

structure = $query-> get_structure
