+# License
+
+Most files in FFmpeg are under the GNU Lesser General Public License version 2.1
+or later (LGPL v2.1+). Read the file `COPYING.LGPLv2.1` 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 the file `COPYING.GPLv2` 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 optimization in the files
+ - `libavcodec/x86/flac_dsp_gpl.asm`
+ - `libavcodec/x86/idct_mmx.c`
+ - `libavfilter/x86/vf_removegrain.asm`
+- the following building and testing tools
+ - `compat/solaris/make_sunver.pl`
+ - `doc/t2h.pm`
+ - `doc/texi2pod.pl`
+ - `libswresample/swresample-test.c`
+ - `tests/checkasm/*`
+ - `tests/tiny_ssim.c`
+- the following filters in libavfilter:
+ - `vf_blackframe.c`
+ - `vf_boxblur.c`
+ - `vf_colormatrix.c`
+ - `vf_cover_rect.c`
+ - `vf_cropdetect.c`
+ - `vf_delogo.c`
+ - `vf_eq.c`
+ - `vf_find_rect.c`
+ - `vf_fspp.c`
+ - `vf_geq.c`
+ - `vf_histeq.c`
+ - `vf_hqdn3d.c`
+ - `vf_interlace.c`
+ - `vf_kerndeint.c`

+ - `vf_super2xsai.c`
+ - `vf_tinterlace.c`
+ - `vf_uspp.c`
+ - `vsrc_mptestsrc.c`
+
+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 the file `COPYING.LGPLv3` or, if you have enabled GPL parts,
+`COPYING.GPLv3` to learn the exact legal terms that apply in this case.
+
+There are a handful of files under other licensing terms, namely:
+
+* The files `libavcodec/jfdctfst.c`, `libavcodec/jfdctint_template.c` and
+ `libavcodec/jrevdct.c` are taken from libjpeg, see the top of the files for
+ licensing details. Specifically note that you must credit the IJG in the
+ documentation accompanying your program if you only distribute executables.
+ You must also indicate any changes including additions and deletions to
+ those three files in the documentation.
+* `tests/reference.pnm` is under the expat license.
+
+
+## External libraries
+
+FFmpeg can be combined with a number of external libraries, which sometimes
+affect the licensing of binaries resulting from the combination.
+
+### Compatible libraries
+
+The following libraries are under GPL:
+- frei0r
+- libcdio
+- librubberband
+- libvidstab
+- libx264
+- libx265
+- libxavs
+- libxvid
+
+When combining them with FFmpeg, FFmpeg needs to be licensed as GPL as well by
+passing `--enable-gpl` to configure.
+
+The OpenCORE and VisualOn 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 these libraries with FFmpeg, the
+license version needs to be upgraded by passing `--enable-version3` to configure.
+
+### Incompatible libraries
+
+There are certain libraries you can combine with FFmpeg whose licenses are not
+compatible with the GPL and/or the LGPL. If you wish to enable these
+libraries, even in circumstances that their license may be incompatible, pass
+`--enable-nonfree` to configure. But note that if you enable any of these
+libraries the resulting binary will be under a complex license mix that is
+more restrictive than the LGPL and that may result in additional obligations.
+It is possible that these restrictions cause the resulting binary to be
+unredistributable.
+
+The Fraunhofer FDK AAC and OpenSSL libraries are under licenses which are
+incompatible with the GPLv2 and v3. To the best of our knowledge, they are
+compatible with the LGPL.
+
+The NVENC library, while its header file is licensed under the compatible MIT
+license, requires a proprietary binary blob at run time, and is deemed to be
+incompatible with the GPL. We are not certain if it is compatible with the
+LGPL, but we require `--enable-nonfree` even with LGPL configurations in case
+it is not.
libraries must be explicitly enabled.
