Error- call with gstreamer

[Leonardo Jose Duarte MendesJunior]

I'm trying to do a call with gstreamer.

This is my pipeline tx:

gst-launch-1.0 autoaudiosrc ! decodebin ! audioconvert ! tee name=split !
queue ! rtpL16pay ! udpsink host=192.168.10.142 port=5000 name=teste
autoaudiosrc ! audioconvert ! audioresample ! lamemp3enc

This is my pipeline rx:

gst-launch-1.0 udpsrc port=5000 name=teste caps="application/x-rtp,
media=(string)audio, format=(string)S32LE, layout=(string)interleaved,
clock-rate=(int)48000, channels=(int)2, payload=(int)0" ! rtpL16depay !
playsink autoaudiosrc ! audioconvert ! audioresample ! lamemp3enc
But when I compile the pipeline(tx), I had this issue:
root at apalis-imx6:~# gst-launch-1.0 autoaudiosrc ! decodebin ! audioconvert
! tee name=split ! queue ! rtpL16pay ! udpsink host=192.168.10.142
port=5000 name=teste autoaudiosrc ! audioconvert ! audioresample !
lamemp3enc

And when I compile the pipeline(rx), I has this issue:

Someone do you have any ideia?
