How to wait for the pipeline destruction

[Elio Francesconi]

No valgrind warning,
I’m using GStreamer to send/recv audio video rtp streams and sometimes I need to close a pipeline and create a new one.
Before create the new one I need to be sure the previous is closed.

I tried sending the EOS message with this code, but the app hangs because I don’t receive any GST_MESSAGE_EOS messages 
if(pPipeline!=NULL)
        {
            GstMessage *msg;
            GstBus *bus = gst_element_get_bus (pPipeline);
            
            /* shut down pipeline (should send EOS message) ... */
            gst_element_send_event (pPipeline, gst_event_new_eos ());
            /* ... and wait for the EOS message from the sink */
            msg = gst_bus_poll (bus, GST_MESSAGE_EOS| GST_MESSAGE_ERROR, -1);
          
            gst_element_set_state(pPipeline, GST_STATE_NULL);
            gst_object_unref(pPipeline);
            pPipeline = NULL;
        }
