6. FFmpeg:
-------

Most files in FFmpeg are under the GNU Lesser General Public License version 2.1 or later (LGPL v2.1+). Read http://www.gnu.org/licenses/old-licenses/lgpl-2.1.html for details. Some other files have MIT/X11/BSD-style licenses. In combination the LGPL v2.1+ applies to FFmpeg.

Some optional parts of FFmpeg are licensed under the GNU General Public License version 2 or later (GPL v2+). See http://www.gnu.org/licenses/old-licenses/gpl-2.0.html 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+.

Specifically, the GPL parts of FFmpeg are

- libpostproc
- optional x86 optimizations in the files
  libavcodec/x86/idct_mmx.c
- the X11 grabber in libavdevice/x11grab.c

There are a handful of files under other licensing terms, namely:

* The files libavcodec/jfdctfst.c, libavcodec/jfdctint.c, libavcodec/jrevdct.c are taken from libjpeg, see the top of the files for licensing details.

Should you, for whatever reason, prefer to use version 3 of the (L)GPL, then the configure parameter --enable-version3 will activate this licensing option for you. Read http://www.gnu.org/licenses/lgpl.html or, if you have enabled GPL parts, read http://www.gnu.org/licenses/gpl-3.0.html to learn the exact legal terms that apply in this case.


external libraries:
-------------------

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 OpenCORE external libraries are under the Apache License 2.0. That license is incompatible with the LGPL v2.1 and the GPL v2, but not with version 3 of those licenses. So to combine the OpenCORE libraries with FFmpeg, the license version needs to be upgraded by passing --enable-version3 to configure.

The nonfree external library libfaac can be hooked up in FFmpeg. You need to pass --enable-nonfree to configure to enable it. Employ this option with care as FFmpeg then becomes nonfree and unredistributable.
