Hi Nicolas, 

Many thanks for your reply! Actually I already wrote a C++ Application and
started the pipelines from there, so no gst-launch. In brief, what would be
required to make it working? What is done differently compared to what
happens at gst-launch? 

Sure, I will check out the rtpsink / rtpsrc elements. Would the following
pipelines be sufficient? 
SENDER: gst-launch-1.0 -v souphttpsrc
! matroskademux ! vp8dec ! x264enc bitrate=5000 ! rtph264pay ! identity
drop-probability=0.01 ! rtpsink address= port=5000
RECEIVER: gst-launch-1.0 -v rtpsrc address= port=5000 !
rtph264depay ! decodebin ! xvimagesink

How would it be made work there? I found a latency property in the rtpsrc,
but nothing being mentioned on retransmission. 

I also find the rtprtxreceive/send elements, which are already available in
my version 1.14.5. What are the differences here?
