 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

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