Object oriented

GStreamer adheres to GObject, the GLib 2.0 object model. A programmer familiar with GLib 2.0 or GTK+ will be comfortable with GStreamer.

GStreamer uses the mechanism of signals and object properties.

All objects can be queried at runtime for their various properties and capabilities.

GStreamer intends to be similar in programming methodology to GTK+. This applies to the object model, ownership of objects, reference counting, etc.
