Thanks for your answer, Zaheer. How can I know which plugins/elements are installed in my system? I know I've installed the core-, base-, ugly- and bad-plugins packages, but how can I know which elements they provide? I have looked at the GStreamer 0.10 Plugins reference manual but I don't see neither mpegpsdemux nor mpegtsdemux in the <a href="http://gstreamer.freedesktop.org/data/doc/gstreamer/head/gst-plugins-bad-plugins/html/">bad plugins reference manual</a>. I would like to know how to find this kind of information as it may be useful for my future development tasks (I need to start with the basic ideas...=) ) Thank you all, Javi <div class="gmail_quote"> 2009/3/6 Zaheer Merali <<a href="mailto:zaheerabbas@merali.org">zaheerabbas@merali.org</a>> <blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"> <div class="im">On Fri, Mar 6, 2009 at 10:56 AM, Javier Gálvez Guerrero <<a href="mailto:javier.galvez.guerrero@gmail.com">javier.galvez.guerrero@gmail.com</a>> wrote: > Hi, > > I solved it.
