About.

GUPnP is an object-oriented open source framework for creating UPnP devices and control points, written in C using GObject and libsoup. The GUPnP API is intended to be easy to use, efficient and flexible.

The GUPnP framework consists of the following libraries:

• GSSDP implements resource discovery and announcement over SSDP.
• GUPnP implements the UPnP specification: resource announcement and discovery, description, control, event notification, and presentation (GUPnP includes basic web server functionality through libsoup). GUPnP does not include helpers for construction or control of specific standardized resources (e.g. MediaServer); this is left for higher level libraries utilizing the GUPnP framework.
• GUPnP-AV is a collection of helpers for building AV (audio/video) applications using GUPnP.
• GUPnP-UI is a collection of GTK+ widgets on top of GUPnP. It features a GtkTreeModel exposing devices discovered by a GUPnPControlPoint and a GtkTreeView for exposing such models.

Bindings currently exist for the Vala language only.

The GUPnP framework was born out of frustration with libupnp and its mess of threads. GUPnP is entirely single-threaded (though asynchronous), integrates with the GLib main loop, and provides the same set of features as libupnp while hiding most of the UPnP internals through an elegant object-oriented design.

The GUPnP framework is free software released under the GNU LGPL.

Also available is a collection of developer tools utilising GUPnP and GTK+, as well as a MediaRenderer version 1 reference implementation.
