Seems good to me. What do you see when you run file FFmpeg-iOS/lib/libavcodec.a? I see the following:

$ file FFmpeg-iOS/lib/libavcodec.a 
FFmpeg-iOS/lib/libavcodec.a: Mach-O universal binary with 4 architectures: [i386:current ar archive random library] [arm64]
FFmpeg-iOS/lib/libavcodec.a (for architecture i386):	current ar archive random library
FFmpeg-iOS/lib/libavcodec.a (for architecture armv7):	current ar archive random library
FFmpeg-iOS/lib/libavcodec.a (for architecture x86_64):	current ar archive random library
FFmpeg-iOS/lib/libavcodec.a (for architecture arm64):	current ar archive random library
