I checked ffmpeg svn log:

Add note about nonfree license of libfaac.

r18715 | diego | 2009-04-29 17:40:25 +0200 (sre, 29 apr 2009) | 3 lines

Require --enable-nonfree for turning on libfaac support.
libfaac lies about being LGPL, when it really is not.



Parts of LICENSE:
Some optional parts of FFmpeg are licensed under the GNU General Public
License
version 2 or later (GPL v2+). See the file COPYING.GPL for details. None
of
these parts are used by default, you have to explicitly pass
--enable-gpl to
configure to activate them. In this case, FFmpeg's license changes to
GPL v2+.

Some external libraries, e.g. libx264, are under GPL and can be used in
conjunction with FFmpeg. They require --enable-gpl to be passed to
configure
as well.


The nonfree external libraries libamrnb, libamrwb and libfaac can be
hooked up
in FFmpeg. You need to pass --enable-nonfree to configure to enable
them. Employ
this option with care as FFmpeg then becomes nonfree and
unredistributable.
Note that libfaac claims to be LGPL, but is not.


Checking faac:
COPYING - LGPL2.1

And in README:
