<div dir="ltr">Hi, Raj:     That's easy. First, connect `notify::source' signal of playbin: // connect signal g_signal_connect(G_OBJECT(playbin), "notify::source", G_CALLBACK(cb_playbin_notify_source), NULL); Then the callback function(I am working on rtsp recently so the example source below is a rtspsrc. In your program, this should be souphttpsrc): static void cb_playbin_notify_source(GObject *obj, GParamSpec *param, gpointer u_data) {     // check whether this is rtsp source     gchar *objname = GST_OBJECT_NAME(obj);     g_message("objname is %s", objname);         // check whether has a `protocols' property     if (g_object_class_find_property(G_OBJECT_GET_CLASS(obj), "source")) {         GObject *source_element;         g_object_get(obj, "source", &source_element, NULL);         if (g_object_class_find_property(G_OBJECT_GET_CLASS(source_element), "protocols")) {             g_object_set(source_element, "protocols", 1, NULL);         }         g_object_unref(source_element);     } } Eric Zhang <div class="gmail_quote">2008/9/12 Raj Swaminathan <<a href="mailto:rajshyam@gmail.com">rajshyam@gmail.com</a>> <blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"><div dir="ltr">Hi, I am trying to stream an Internet Radio Channel with playbin. I am going through a proxy and can use gst-launch in this way to successfully play the station: gst-launch souphttpsrc proxy=<a href="http://proxyURL" target="_blank">http://proxyURL</a> location=<a href="http://myIRadio.com" target="_blank">http://myIRadio.com</a>. ! mad ! alsasink I do not need to use gst-launch and am actually building my own software media player .... When i do not setup proxy but just run my mediaplayer with playbin, I just wait on an endless loop and get the following debug message on cancelling.. gstsouphttpsrc.c(683): gst_soup_http_src_finished_cb(): /play/source libsoup status code 1 Error: Cancelled So playbin is trying to use souphttpsrc but Im assuming the error is becoz the proxy is not set ..... Can someone plz suggest how to set the proxy property with souphttpsrc and still use playbin v1 ?
