Cisco Cisco IPICS Release 2.1 Licensing Information

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.

FFmpeg contains source code under both GPL and LGPL. We avoid using any GPL code in our project by disable

macros ARCH_X86, HAVE_MMX, HAVE_MMX2, and CONFIG_GPL. This way, our complied DLL are 100%

covered by LGPL v2.1 and later.    

   

We build FFmpeg to several DLLs in case functionality requirement and our product links to the related DLLs via

dynamic link method.    

   

We add our own code to wrap FFmpeg DLLs. We are ready to publish the code to public.
