Thanks a lot for the reply!

To a)
Server:
 gst-launch-1.0 videotestsrc horizontal-speed=5 ! x264enc tune="zerolatency"
threads=1 ! tcpserversink port=8554
Receiver:
 gst-launch-1.0 tcpclientsrc port=8554 host=localhost ! h264parse !
avdec_h264 ! xvimagesink

*The receiver does not go from the Prerolling into the Playing state. I
somehow should to say to the piple to be live which does not need to
preroll. How can I do this?*


To b)
Server:
 gst-launch-1.0 videotestsrc horizontal-speed=5 ! x264enc tune="zerolatency"
threads=1 ! rtph264pay config-interval=1 ! gdppay ! tcpserversink port=8554
Receiver:
 gst-launch-1.0 tcpclientsrc port=8554 host=localhost ! gdpdepay !
application/x-rtp, payload=96 ! rtpjitterbuffer ! rtph264depay ! avdec_h264
! xvimagesink

This works. But well its somewhat in a roundabout way and has quiet some
overhead.


To c)
Server:
 gst-launch-1.0 videotestsrc horizontal-speed=5 ! x264enc tune="zerolatency"
threads=1 ! mpegtsmux ! tcpserversink port=8554 
Receiver:
 gst-launch-1.0 tcpclientsrc port=8554 host=localhost  ! tsdemux ! h264parse
! avdec_h264 ! xvimagesink
 
This works fine. Is it normal that there must be no tsparse before the
tsdemux?
