I did the following steps to install good,bad,ugly and base plugins from gstreamer: sudo apt-get install gstreamer0.10-plugins-good sudo apt-get install gstreamer0.10-plugins-bad sudo apt-get install gstreamer0.10-plugins-ugly sudo apt-get install gstreamer0.10-plugins-base </blockquote><div> [deletia] </div><blockquote class="gmail_quote" style="margin: 0pt 0pt 0pt 0.8ex; border-left: 1px solid rgb(204, 204, 204); padding-left: 1ex;">Now when I do gst-inspect | grep osssink, I don't find any results. same happening with some other plugins also e.g. alsasink, oggdemux etc. </blockquote> I'm guessing you have plugins installed in multiple directories. Run gst-inspect without any arguments, and choose a plugin at random. Run gst-inspect for the plugin you chose and examine the Filename detail. If you look in that directory, I'm guessing you'll not find the osssink plugin in that directory. If this is the problem, and you need multiple plugin directories, this page describes that: <a href="http://www.gstreamer.net/data/doc/gstreamer/head/gstreamer/html/gst-running.html">http://www.gstreamer.net/data/doc/gstreamer/head/gstreamer/html/gst-running.html</a> If you don't need multiple directories, you can just delete (or rename to be conservative) the directory that is being picked up instead of the correct one.
