Here is my working Configure for cross-compiling FFmpeg on iOS 6 the arch is ARMv7

NOTE: You must have to have gas-preprocessor.pl inside /usr/local/bin/ please do not continue until you have gas-preprocessor.pl on your bin directory

  • Download FFmpeg 1.0 "Angel" from here

  • Unzip it and place it somewhere i.e. your Desktop folder

  • Open terminal and browse to unzipped FFmpeg folder

  • Copy and paste the following command, (be patient will take a while)

./configure --disable-doc --disable-ffmpeg --disable-ffplay --disable-ffserver --enable-cross-compile --arch=arm --target-os=darwin --cc=/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/gcc --as='gas-preprocessor/gas-preprocessor.pl /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/gcc' --sysroot=/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS6.0.sdk --cpu=cortex-a8 --extra-cflags='-arch armv7' --extra-ldflags='-arch armv7 -isysroot /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS6.0.sdk' --enable-pic --enable-decoder=rawvideo --disable-asm

  • Now type the following command on terminal make (wait a little more)

  • Once it has finished now type on terminal sudo make install (wait again)

  • Go to /usr/local/lib to find your freshly baked armv7 libs

  • Enjoy!


    Added Support for armv7s

    This armv7s configure is totally untested and i dont really know if this would work, i don't own an iPhone 5 so we need someone to test the final armv7s libs

    ./configure --disable-doc --disable-ffmpeg --disable-ffplay --disable-ffserver --enable-cross-compile --arch=arm --target-os=darwin --cc=/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/gcc --as='gas-preprocessor/gas-preprocessor.pl /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/gcc' --sysroot=/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS6.0.sdk --cpu=cortex-a8 --extra-cflags='-arch armv7s' --extra-ldflags='-arch armv7s -isysroot /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS6.0.sdk' --enable-pic --enable-decoder=rawvideo --disable-asm
