A problem with running gstreamer pipeline on Xubuntu

[Eskender]

Hi everyone,
 
My problem is that i get an Error message when i'm trying to run this pipeline on Xubuntu system
udpsrc port=1234 ! theorasink ! autovideosink.
I emphasize Xubuntu, because the same line perfectly runs on my home Ubuntu. Thus, it's really hard for me to get what is the problem. I have installed all missing plug-ins for gstreamer that were not in Xubuntu. Actually the Error says
"autovideosink(): Could not initialize supporting library".
Although, it perfectly works when i try
 v4l2src ! autovideosink.
 Hope that someone can give me a solution for this problem. Thanks in advance.

I never seen 'theorasink' element around (I use Ubuntu), what does it do?

What are you trying to do?

Notice that udpsrc doesn't put caps on its buffers, so it is usually a good idea to set the caps property so it can add it to its buffers. IIRC not having caps on buffers causes the xvimagesink error you mention.

Of course that only makes sense if theorasink element exists and if it also doesn't put caps on buffers.

Thank you thiagossantos for your help.
I'm very sorry. I misspelled it. It's not theorasink, it's theoradec of course. I'm trying to send a live stream from a web cam on a Linux system using either UDP or RTP. I'm pretty new in this field, so I need to do a lot of experimenting. I've found this example in an article in
French http://blog.nicolargo.com/2009/02/jai-streame-avec-gstreamer.html. It's shows different pipeline types to send a stream through a network. For now the main problem that concerns me is why what perfectly works on Ubuntu gives, currently difficult for me to explain, errors on Xubuntu. As far as I know the main difference between these two systems is on the interface level, what it has to do with the gstreamer? This forum is the only hope for me. It seems that there is not much useful help elsewhere.
