  3. Get the latest FFmpeg from SVN (minimum r20151).
  4. Configure FFmpeg with one of the following commands. These give a
    clean build with a default installation of iPhone SDK 3.1 on OSX Leopard.
    Other versions may vary.
  5. For iPhone 3GS or iPod Touch 3G 32GB/64GB, use this command:

    ./configure --cc=/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/arm-apple-darwin9-gcc-4.2.1 --as='gas-preprocessor.pl /Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/arm-apple-darwin9-gcc-4.2.1' --sysroot=/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS3.1.sdk --enable-cross-compile --target-os=darwin --arch=arm --cpu=cortex-a8 --enable-pic
  6. For other iPhone or iPod Touch models, use this command:

    ./configure --cc=/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/arm-apple-darwin9-gcc-4.2.1 --as='gas-preprocessor.pl /Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/arm-apple-darwin9-gcc-4.2.1' --sysroot=/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS3.1.sdk --enable-cross-compile --target-os=darwin --arch=arm --cpu=arm1176jzf-s
