Gstreamer not using multi core on linode server

I have been trying to run a gstreamer application written in python to run on linode server, for some reason the application is not using up the multi core that is available instead it runs on a single core. But on the other hand when I am trying to run the same app on my system it uses all my 8 core to process the video. Is there something specific that I need to do to make it work on multicores.

I use gstreamer0.10 and python 2.7. Thanks in advance.
