First Plugin - Compiling and installation
 
|
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. Thanks, Ionut

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:

Chances are that the default prefix (/usr/local/) was used, so your plugin got installed into /usr/local/lib/gstreamer-0.10/, while you're using GStreamer packages which usually go into the /usr prefix and will only look in /usr/lib/gstreamer-0.10/ for plugins. You could try a) copying the plugin .so into ~/.gstreamer-0.10/plugins/ b) use export GST_PLUGIN_PATH=/usr/local/lib/gstreamer-0.10/ c) re-run autogen.sh or configure with --prefix=/usr (not recommended) Cheers -Tim ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.

Hi, Thanks a lot guys, export GST_PLUGIN_PATH=/usr/local/lib/gstreamer-0.10/ did the trick. I still have a question about the registry.CPU.xml file under ~/gstreamer-0.10. What is his purpose? It should list all the installed plugins, and since my make install rule executed successfully I would expected to add the plugin in the registry, but obviously this was not the case.

The file caches information about plugins previously found, so that information is available without loading and inspecting all .so plugin files at every gst_init(). It is usually (re-)generated from within gst_init() if necessary, and will not be touched by any plugin installation/deinstallation (even less so since the cache is per-user).
