Specifically, the GPL parts of FFmpeg are
- libpostproc
-- some x86 optimizations in libswscale
+- 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
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 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.
