linking pads from multiqueue to splitmuxsink?

[killerrats]

edited the code. i put the wrong call in the post.

gst-launch-1.0 -e --gst-debug=3 

udpsrc address=[IP] port=[PORT] caps=application/x-rtp,media=audio ! 
rtppcmudepay ! audioparse rate=8000 channels=1 rate=32000 ! audioconvert ! 
avenc_aac ! aacparse ! tee name=atee ! mq.sink_2 

udpsrc address=[IP] port=[PORT] 
caps=application/x-rtp,media=video,payload=90000 ! queue ! rtpmp4vdepay ! 
mpeg4videoparse ! tee name=vtee 

! mq.sink_1 multiqueue name=mq mq.src_1 ! mux.video splitmuxsink name=mux 
muxer=mp4mux sink=filesink max-size-bytes=20971520 max-files=360 
location=c:/temp/video%04d.mp4 

mq.src_2 ! mux.audio_1 -v 

this pipeline is successful in the command line but when I create the 
elements and join them it won't work on the audio side. 

when I join the mq.src_2 -> mux.audio_1 it says wrong hierarchy. Both udpsrc 
are in the same bin. If I only use the video side it will work. this is 
setting up the pipeline before playing. I will use similar way for the rest 
of the pad linking in the pipeline to join the elements. Anybody know a 
reason? 

*
GstElement* mq = gst_bin_get_by_name(this->srcPipeline, 
V_MULTIQUEUE_NAME); 
GstElement* mux = gst_bin_get_by_name(this->srcPipeline, 
V_MUXER_NAME); 
*
GstPad* srcPad = gst_element_get_static_pad(mq, "src_2"); 
GstPad* sinkPad = gst_element_get_request_pad(mux, "audio_1"); 

if (gst_pad_link(srcPad, sinkPad) != GST_PAD_LINK_OK) 
{ 
check = false; 
}
