When you say "my application", do you mean totem, or an application you
have written yourself.

GStreamer should be able to support that fine. For example, after Totem
has triggered the automatic installation of some missing plugins, and
they were installed successfully, it should call gst_update_registry(),
which in turn should re-scan the available plugins and pick up any new

If that doesn't work, that's probably a bug somewhere, and you should
file a bug in the Ubuntu bug tracker about this then.
