How to use Concat element

Hi,
I was trying to use Concat element but. My first video is shown but not the second.
I use this pipeline:
#define DEF_PIPELINE "concat name=c ! avdec_h264 name=avdec_h264 skip-frame=1 ! videorate max-rate=6 name=videorate ! x264enc speed-preset=1 pass=5 bitrate=300 key-int-max=6 name=x264enc ! rtph264pay config-interval=1 pt=96 name=rtph264pay ! udpsink name=udpsink filesrc name=fsrc ! qtdemux ! h264parse ! c."
After I initialize fsrc location, udp port....
And finally I add a second video with:
GstPadTemplate *sink_pad_template;
GstElement * fsrcAux;
GstElement * qtdemuxAux;
GstElement * h264parseAux;
GstPad *pad;
GstPad *srcpad;
fsrcAux = gst_element_factory_make ("filesrc", NULL);
g_object_set (fsrcAux, "location", video.c_str() , NULL);
qtdemuxAux = gst_element_factory_make ("qtdemux", NULL);
h264parseAux = gst_element_factory_make ("h264parse", NULL);
GstElement *gSc;
gSc=gst_bin_get_by_name(GST_BIN(m_gstPipeline), "c");
if(!gSc)
{
LOG(ERROR)<<"gSc created failed.";
return ;
}
gst_element_link_many (fsrcAux, qtdemuxAux, h264parseAux, NULL);
pad= gst_element_get_request_pad (gSc, "sink_%u");
if(pad==NULL){
LOG(ERROR)<<"pad NULL";
return ;
}
srcpad = gst_element_get_static_pad (h264parseAux, "src");
if(srcpad==NULL){
LOG(ERROR)<<"sink NULL";
return ;
}
gst_pad_link (srcpad, pad);
I can see first streaming but no second. EOS is not publish so second sink is active but no data.
I activate DEBUG_LEVEL_LOG and last lines are:
