 So FFmpeg does not build.

 This looks very similar to 55198 -- the complaint about linking with the
 wrong system library/framework.

 ffmpeg-4.0.2_1+gpl2.darwin_13.x86_64

 So I'm only using "gpl2" as the only option on ffmpeg.

 I also get these compiler messages over and over:

 warning: unknown warning option '-Werror=partial-availability'; did you
 mean '-Werror=availability'? [-Wunknown-warning-option]
 warning: unknown warning option '-Wno-bool-operation'; did you mean '-Wno-
 bool-conversion'? [-Wunknown-warning-option]
