Not without more details, like where the EOS comes from. Check the
debug logs.


Also better use rpicamsrc instead of something with fdsrc:
https://github.com/thaytan/gst-rpicamsrc


And using RTP together with GDP does not make much sense, just using
GDP alone will work the same way without another layer in between. But
you might just want to use gst-rtsp-server on the server and rtspsrc on
the client instead of something complicated around the TCP elements.
