I don't know whether it's appropriet to post this question here, but I can't find a GLIB maillist.

It seems GStreamer borrows this from GLib. After reading the application guide and plugin guide, I can only see how to define and register an interface(Using g_type_add_interface_static). But I can't find an example about how to query an interface and use it. I looked into GLib documentation and find two APIs: - gpointer    g_type_interface_peek(             gpointer instance_class,             GType iface_type); - G_TYPE_INSTANCE_GET_INTERFACE() I think they are used to query the registered interfaces, am I right? I am new to GLib and GStreamer, so if you could kindly give me a whole picture of how to register, query and use interfaces, it will be very helpful! Thanks in advance!
