If you use G_TYPE_POINTER, the type system doesn't know how to copy or free your data, so it's up to you to take care of this. What you should do is register a 'boxed type' for your structure, like this: static MyInfo * my_info_ref (MyInfo * info) {   if (info != NULL)     g_atomic_int_inc (&info->refcount);   return info; } static void my_info_unref (MyInfo * info) {   /* if we ended up with the refcount at zero, free it */   if (g_atomic_int_dec_and_test (&info->refcount)) {     /* g_free (info->foo); */     /* g_free (info);      */   } } #define MY_TYPE_INFO my_info_get_type() static GType my_info_get_type (void) {   static volatile gsize type = 0;   if (g_once_init_enter (&type)) {     GType tmp;     tmp = g_boxed_type_register_static ("MyInfo",         (GBoxedCopyFunc) my_info_ref,         (GBoxedFreeFunc) my_info_unref);     g_once_init_leave (&type, tmp);   }   return type; } Then you can use: > structure = gst_structure_new("FILTERMESSAGE", >    "info", MY_TYPE_INFO, myinfo, NULL); > my_info_unref (myinfo); and the info will be freed automatically with the message later (unless you are still holding refs). >  gst_bus_post (bus, msg); Use gst_element_post_message(). > On the other side, I have my application that watches the bus > messages, and gets my info: >    case GST_MESSAGE_APPLICATION: >        const GstStructure *structure = > gst_message_get_structure(message); >        MyInfo* info; >        info = > (MyInfo*)g_value_get_pointer(gst_structure_get_value(structure, > "info")); You can then use _get_boxed() here (to just get a pointer to your info structure), or _dup_boxed() (to get a pointer and a reference). > Cheers -Tim PS: you still have not filed a bug about that MTS typefind problem from a few days ago.
