If the “post-messages” property of multifilesink is TRUE, it sends an
application message named
"GstMultiFileSink" after writing each file and message to be parsed in the
pipeline or bin bus. like below

case GST_MESSAGE_ELEMENT:
{
        const gchar *filename;
        gint index;
        GstClockTime timestamp, stream_time, running_time, duration;
        guint64 offset, offset_end;

        GstStructure *s = gst_message_get_structure (msg);
        filename = gst_structure_get_string (s, "filename");
        gst_structure_get_string (s, "index", &index);
        gst_structure_get_clock_time (s,"timestamp",&timestamp);
        gst_structure_get_clock_time (s,"stream-time",&stream_time);
        gst_structure_get_clock_time (s,"running-time",&running_time);
        gst_structure_get_uint64(s, "offset", &offset)
        gst_structure_get_uint64(s, "offset-end", &offset_end);
}
break;
