Hi! thank you for your reply!

now I can see that im doing something wrong, this is the server command with
-v:


gst-launch -v videotestsrc ! ffenc_mpeg4 ! rtpmp4vpay ! udpsink
host=192.168.1.16 port=5000

Pipeline is PREROLLED ...
Setting pipeline to PLAYING ...
New clock: GstSystemClock

now I noticed that there are several caps in the client side, of several
filters...
so how the client command supposed to look like?
thank you for your help!
