NAME

GStreamer::Interfaces - Perl interface to the GStreamer Interfaces library

SYNOPSIS

  use GStreamer::Interfaces;
  # GStreamer::PropertyProbe
  my $sink = GStreamer::ElementFactory -> make(alsasink => "sink");
  my $pspec = $sink -> get_probe_property("device");
  if ($sink -> needs_probe($pspec)) {
    $sink -> probe_property($pspec);
  }
  my @devices = $sink -> get_probe_values($pspec);
  # GStreamer::XOverlay
  my $overlay = GStreamer::ElementFactory -> make(xvimagesink => "overlay");
  $overlay -> set_xwindow_id($xid);

ABSTRACT

GStreamer::Interfaces provides access to some of the interfaces in the GStreamer Interfaces library. Currently, that's GStreamer::PropertyProbe and GStreamer::XOverlay.

INTERFACES

GStreamer::PropertyProbe

pspecs = $element->get_probe_properties

pspec = $element->get_probe_property (name)

bool = $element->needs_probe (pspec)

$element->probe_property (pspec)

values = $element->probe_get_probe_values (pspec)

bool = $element->needs_probe_name (name)

$element->probe_property_name (name)

values = $element->get_probe_values_name (name)

values = $element->probe_get_probe_values_name (name)

GStreamer::XOverlay

$overlay->set_xwindow_id (xwindow_id)

$overlay->expose

$overlay->got_xwindow_id (xwindow_id)
