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 optimizations in the files - - `libavcodec/x86/flac_dsp_gpl.asm` - - `libavcodec/x86/idct_mmx.c` - - `libavfilter/x86/vf_removegrain.asm` -- libutvideo encoding/decoding wrappers in - `libavcodec/libutvideo*.cpp` -- the X11 grabber in `libavdevice/x11grab.c` -- the swresample test app in - `libswresample/swresample-test.c` -- the `texi2pod.pl` tool -- the following filters in libavfilter: - - `f_ebur128.c` - - `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_mcdeint.c` - - `vf_mpdecimate.c` - - `vf_owdenoise.c` - - `vf_perspective.c` - - `vf_phase.c` - - `vf_pp.c` - - `vf_pp7.c` - - `vf_pullup.c` - - `vf_sab.c` - - `vf_smartblur.c` - - `vf_repeatfields.c` - - `vf_spp.c` - - `vf_stereo3d.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 -- libutvideo -- 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 ----------------------- - -The Fraunhofer AAC library and FAAC are under licenses which -are incompatible with the GPLv2 and v3. We do not know for certain if their -licenses are compatible with the LGPL. -If you wish to enable these libraries, 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 unredistributeable. |
