Greetings again, I am working on my on this project of mine which i find
very educational. 

Again, what i am trying to achieve is to forward an rtp traffic from a
source to a pc (named pc1) and then forward again on other pc (named pc2)
which will receive a either transcoded form or display as is. What i have
achieved so far: 

1. Transfer an mp4 from one pc to another.
2. Forward rtp traffic from pc1 to pc2 and then saved to a filesink on pc2

What i have a problem right now is that i want to extend my 2nd achievement
(described above) to something more:

3. Receive rtp traffic, store it to a filesink and forward using udpsink (a
mix of 1 and 2 described above)

I provide my pipelines for both 1,2 and 3 but no.3 needs some modification 

Sender: 

gst-launch-1.0 -v filesrc location = test.mp4 ! qtdemux ! h264parse !
avdec_h264 ! videoconvert ! x264enc ! rtph264pay ! udpsink
host=192.168.10.18 port = 5000

Receiver

1. gst-launch-1.0 -e udpsrc port=5000 caps="application/x-rtp ,
media=(string)video , clock-rate=(int)90000, encoding-name=(string)H264" !
rtpjitterbuffer latency=100 ! rtph264depay ! h264parse ! mp4mux ! filesink
location=try.mp4

2. gst-launch-1.0  -v udpsrc port=5000 ! -e udpsink host= 192.168.10.19 port
= 5001    
# this is pc1 and excute the 1st  Receiver pipeline on pc2 to store the
traffic on pc2, modyfying 
# ports and addresses

3. gst-launch-1.0 udpsrc port=5000 -e -v tee name=tp  tp.  ! queue ! udpsink
host=192.168.10.19 port=5001 tp. ! queue ! caps="application/x-rtp ,
media=(string)video , clock-rate=(int)90000, encoding-name=(string)H264" !
rtpjitterbuffer latency=100 ! rtph264depay ! h264parse ! mp4mux ! filesink
location=my.mp4

#The above gives this error:  link without source element. I am trying to
understand if i have split the pipeline correct or not using tee to and
queue .

Any advice would be very helpful.

Best Regards,
S.
