GStreamer::Query(3pm)
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
