Disclaimer: The GStreamer team makes a real effort to make sure that
the information in this file is as up-to-date and accurate as possible.
However, this file may contain errors and omissions. Some dependant
libraries change their licensing from version-to-version and some of
the libraries listed here as LGPL were under the GPL license in
older releases. Distributions which include GStreamer are responsible
for ensuring that plugins are used in accordance with licensing terms
and other laws.
GStreamer is developed under the terms of the LGPL (see LICENSE file for details).
Some of our plugins however rely on libraries which are available under other
licenses. This means that if you are using an application which has a non-GPL
compatible license, for instance a closed-source application with GStreamer
you have to make sure not to use GPL linked or derived plugins. When using
GPL linked plugins GStreamer is for all practical reasons under the GPL itself.
The plugins which use a GPL library are as follows:

Unsure:
faad libfaad (http://www.audiocoding.com/)
faad's license depends on its major version :
- for FAAD1 : it is LGPL
- for FAAD2 : it is GPL
look at these pages for more information on licenses :
http://www.audiocoding.com/modules/wiki/?page=FAAD2
http://www.audiocoding.com/modules/wiki/?page=FAAC
by default, GStreamer faad plugin would compile against FAAD2 if available.
it falls back to FAAD1 if not.
