Wrong, mostly.
Any changes you make to the encoder library itself would be LGPL, but if all you are doing is calling the library from other code then that is not an issue.
If you make a change to the library, even as part of a larger project, nothing else but that change is forced to be LGPL licensed. If your update is a bit of code you use elsewhere, as long as you own that code it does not force the elsewhere to be LGPL - while you are forced to LGPL the change to the library there is no stipulation that you can't dual license and use the same code under completely different terms outside the library.
