This is a way to do it and it's reported in example
+static GstBusSyncReply
+sync_bus_handler(GstBus * bus, GstMessage * message, GstElement * bin)
+{
...
+                       case GST_STREAM_STATUS_TYPE_ENTER:
+                               if (task) {
+                                       g_message
+                                           ("raising task priority for %p",
+                                            task);
+                                       gst_task_set_priority(task,
+                                                             G_THREAD_PRIORITY_HIGH);
+                               }
+                               break;
...
                bus = gst_pipeline_get_bus(GST_PIPELINE(pipeline));
+               gst_bus_set_sync_handler(bus,
+                                        (GstBusSyncHandler) sync_bus_handler,
+                                        bin);
