Echo filter use with UDP

Andrés Meseguer Valenzuela

Hi, I am trying to send video and audio muxed via UDP to another PC  
and to receive a similar signal of muxed audio and video from this PC,  
but using echo filters.

My problem is that I receive the signal from the desired computer, but  
this computer does not receive any signal that I send. Hence, I would  
like to know, how to solve this.

I am using the following script to do this.

ENTRYPOINT gst-launch-1.0 -v v4l2src device=/dev/video0 ! video/x-raw,  
height=480 ! videoconvert \
! x264enc noise-reduction=1000 tune=zerolatency byte-stream=true  
threads=4 key-int-max=15  intra-refresh=true \
! queue ! mpegtsmux name=mux ! queue ! udpsink host=  
port=5605 alsasrc \
! queue ! webrtcdsp ! audioconvert \
! queue ! opusenc audio-type=2051 inband-fec=true ! queue ! mux.  
udpsrc port=9100 ! queue ! tsdemux latency=0 name=demux demux. \
! queue ! h264parse ! queue ! avdec_h264 ! queue ! videoconvert \
! autovideosink demux. ! queue ! opusdec ! queue ! audioconvert !  
queue ! webrtcechoprobe ! alsasink sync=true

Thanks for your help.
