How to use Concat element
 
|
Hi,
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: concat gstconcat.c:495:gst_concat_switch_pad:<c>[00m <c:sink_0> to <c:sink_1> 0:00:53.703260401 [334m21777[00m 0x1622a80 [33;01mLOG [00m [00;01;37;44m GST_PROPERTIES gstobject.c:448:gst_object_dispatch_properties_changed:<pipeline0>[00m deep notification from c (active-pad) 0:00:53.703344451 [334m21777[00m 0x1622a80 [33;01mLOG [00m [00;01;37;41m GST_MESSAGE gstmessage.c:301:gst_message_new_custom:[00m source c: creating new message 0x169c600 duration-changed 0:00:53.703443576 [334m21777[00m 0x1622a80 [37mDEBUG [00m [00;43m GST_BUS gstbus.c:318:gst_bus_post:<bus15>[00m [msg 0x169c600] posting on bus duration-changed message: 0x169c600, time 99:99:99.999999999,
