Sorry for my bad english!
Thanks in advance,
I'm new to Ubuntu too, so all is very difficult for me!
I have downloaded "gst-rtsp-server-1.4.5" from http://gstreamer.freedesktop.org/src/gst-rtsp-server/
and I have unzipped it.
Now I made ".configure", "make" and "sudo make install" by command line and all seems ok.
But I think there is something else which doesn't work right, can you help me?
If I do "make check" the result is this:
