Gst::DoubleRange is used to use to store a double precision floating point range in Gst::Structures of Gst::Caps as a value representing a property (see GStreamer Application Development Manual section 8.2.2 and GstValue docs). When the value is set, it is transformed to a GStreamer GType so retrieving the value is a bit different. The class can be used in setting and getting a Gst::Structure field like so:
Glib::Value<Gst::DoubleRange> value; value.init(Glib::Value<Gst::DoubleRange>::value_type()); value.set(Gst::DoubleRange(44.1, 48.0)); Gst::Structure structure("my-structure"); structure.set_field("rate", value); ... Glib::ValueBase gst_value; structure.get_field("rate", gst_value); Gst::DoubleRange range(gst_value); double min = range.min; ...
