This is a shell script to build FFmpeg libraries for iOS and tvOS apps.

Tested with:

• FFmpeg 3.4
• Xcode 9

• https://github.com/libav/gas-preprocessor
• yasm 1.2.0

Use build-ffmpeg-tvos.sh for tvOS.

• To build everything:

    ./build-ffmpeg.sh
  

• To build arm64 libraries:

    ./build-ffmpeg.sh arm64
  

• To build fat libraries for armv7 and x86_64 (64-bit simulator):

    ./build-ffmpeg.sh armv7 x86_64
  

• To build fat libraries from separately built thin libraries:

    ./build-ffmpeg.sh lipo
