Hi, everyone.    I will use multiudpsink to send udp data to my clients, and I want to get some running parameters of every client through multiudpsink.  I have got a method from    >>>http://gstreamer.freedesktop.org/data/doc/gstreamer/head/gst-plugins-good-plugins/html/gst-plugins-good-plugins-multiudpsink.html. first, I will set a callback handle to signal "get-stats"      g_signal_connect(m_multiudpsink, "get-stats", G_CALLBACK(callback_multudpsink_state), (gpointer)data); then, emit signal "get-stats" by      g_signal_emit_by_name(m_multiudpsink, "get-stats",host, port, m_Property); With the document of multiudpsink, we can get client's state will be returned  by my callback function. ************************************************************* My question is how or where can I get pointer of GValueArray ? ************************************************************* <pre class="programlisting"><a target="_blank" href="http://library.gnome.org/devel/gobject/unstable/gobject-Value-arrays.html#GValueArray">GValueArray</a>* user_function (<a target="_blank" class="link" href="http://gstreamer.freedesktop.org/data/doc/gstreamer/head/gst-plugins-good-plugins/html/gst-plugins-good-plugins-multiudpsink.html#GstMultiUDPSink">GstMultiUDPSink</a> *gstmultiudpsink, <a target="_blank" href="http://library.gnome.org/devel/glib/unstable/glib-Basic-Types.html#gchar">gchar</a> *host, <a target="_blank" href="http://library.gnome.org/devel/glib/unstable/glib-Basic-Types.html#gint">gint</a> port, <a target="_blank" href="http://library.gnome.org/devel/glib/unstable/glib-Basic-Types.html#gpointer">gpointer</a> user_data)</pre> Thanks ! <div> <div>libing195@163.com </div> </div>
