FFmpeg:  

-------  

 

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 MMX optimizations for YUV to RGB colorspace conversion in  

 libswscale/x86/yuv2rgb_template.c  

- optional x86 optimizations in the files  

 libavcodec/x86/h264_deblock_sse2.asm  

 libavcodec/x86/h264_idct_sse2.asm  

 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 the file COPYING.LGPLv3 or, if you have enabled GPL parts,  

COPYING.GPLv3 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
