# GStreamer::Query(3pm)

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

## 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;
```
