AW: not able to get callbacks from splitmuxsink

[Thornton, Keith]

Hi,
First of all you need to set the message-forward parameter
g_object_set(G_OBJECT(m_pPrimaryMuxSink), "message-forward", TRUE, nullptr);

and then where you handle bus messages you need something like
            case GST_MESSAGE_ELEMENT:
            {
                if (gst_message_has_name(message, "splitmuxsink-fragment-opened"))
                {
                    isOpen = true;
                }
                else if (!gst_message_has_name(message, "splitmuxsink-fragment-closed"))
                {
                    isClose = true;                }
                    busReply = GST_BUS_PASS;
                    break;           }

Betreff: not able to get callbacks from splitmuxsink

Hello,

        I want to get  "splitmuxsink-fragment-opened" and "splitmuxsink-fragment-closed" messages from splitmuxsink.
I have tried adding a pad to the splitmuxsink and subscribed to the message.
	GstPad *ghostpad = gst_ghost_pad_new_no_target("sink", GST_PAD_SINK);
	auto si = gst_element_add_pad(splitmuxsink, ghostpad);
	auto ghostpadactive = gst_pad_set_active(ghostpad, true);
	auto ghostpadprobe = gst_pad_add_probe(ghostpad, GST_PAD_PROBE_TYPE_DATA_DOWNSTREAM, gstUpdateCb, this, nullptr);
	auto ghostpadadded = gst_element_add_pad(splitmuxsink, ghostpad);

Also I tried adding a watch to the bus and implementing the synchandler.
	auto bus = gst_element_get_bus(GST_ELEMENT(splitmuxsink));
	gst_bus_add_signal_watch(bus);
	gst_bus_enable_sync_message_emission(bus);
	gst_bus_set_sync_handler(bus, (GstBusSyncHandler)my_bus_callback, this, NULL);
	gst_object_unref(bus);

Both the approaches are not working.please suggest a solution.

Thanks & Regards,
Shyam
