What do you mean with plugins that don't have a shared library? All of
the ones shipped with the binaries should have a shared library in
lib/gstreamer-1.0 and a corresponding static one in lib/gstreamer-
1.0/static.

The static ones need special attention to work, check
GST_STATIC_PLUGIN_DECLARE() and GST_STATIC_PLUGIN_REGISTER() in the
docs for seeing how that works.

The dynamic ones only need to be in a path that is considered by the
GstRegistry. This is configured via the GST_PLUGIN_PATH,
GST_PLUGIN_SYSTEM_PATH environment variables and API on GstRegistry.
