Hi! I had this problem and  it was because gstreamer looked for plugins in /usr/lib/gstreamer/... and mine was instaled in /lib/gstreamer/... (or something like that). Try using the --prefix=/usr option when configuring. There are a copule of arguments for gst-inspect and gst-launch that can be usefull too: <dl><dt>--gst-plugin-path=PATH </dt><dd>Add directories separated with ':' to the plugin search path</dd><dt>--gst-plugin-load=PLUGINS </dt><dd>Preload plugins specified in a comma-separated list. Another way to specify plugins to preload is to use the environment variable GST_PLUGIN_PATH</dd></dl>With these, you don't even have to install the plugin. I hope it helps <div>On 3/7/08, Ionut Dediu <<a href="mailto:deionut@yahoo.com">deionut@yahoo.com</a>> wrote:<blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"> Hi, I am trying to get started with GStreamer plugin devel. I wrote a basic plugin, based on the gst-template plugin. I compiled and installed it with autogen.sh make and make install from the top directory. All steps seem to be successful. However I want to inspect it using gst-inspect mypluginname, but it gives me the following error: No such element or plugin 'mypluginname'... I have also looked in the registry file under ~/.gstreamer-0.10/registry.i486.xml to see if this file was modified to include my plugin, but it wasn't. So what are the necessary steps to correctly build and install a "Hello World" plugin? What does installing a plugin mean? Will its library be copied to a certain location and/or the plugin has to be included in the rtegistry xml file? Needles to say the Plugin Writer's Guide fails to mention anything about compling and installing a plugin.
