Build FFmpeg with xCode 5

问题:

Does anyone know how to compile FFmpeg with xCode 5?

My configure part:

./configure --disable-doc --disable-ffmpeg --disable-ffplay --disable-ffserver --enable cross-compile --arch=arm --target-os=darwin --enable-neon --disable-avfilter \ --disable-bsfs \ --enable-avresample --enable-swresample --disable-iconv --enable-gpl \ --disable-demuxers --enable-demuxer=rtsp --enable-demuxer=rtp --enable-demuxer=mpegts \ --disable-decoders --enable-decoder=mp2 --enable-decoder=mp3 --enable-decoder=mpeg2video --enable-decoder=ac3 - enable-decoder=dvbsub --enable-decoder=h264 \ --disable-parsers --enable-parser=mpegvideo - enable-parser=mpeg4video --enable-parser=mpegaudio --enable-parser=dvbsub\ --disable-muxers --disable-encoders --disable-filters \ --disable-protocols --enable-protocol=http --enable-protocol=rtp --enable-protocol=udp --enable-protocol=tcp \ --disable-swscale-alpha \ --disable-armv5te \ --disable-armv6 \ --disable-armv6t2 \ --cc=/Applications/Xcode.app/Contents/Developer/usr/bin --as='/usr/local/bin/gas preprocessor/gas-preprocessor.pl /Applications/Xcode.app/Contents/Developer/usr/bin' --sysroot=/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS7.0.sdk --cpu=cortex-a8 --extra-cflags='-arch armv7 -mfpu=neon -mfloat-abi=softfp' --extra-ldflags='-arch armv7 -mfpu=neon -mfloat-abi=softfp -isysroot /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS7.0.sdk' --enable-pic --disable-bzlib

It works with xCode 4 (different Compiler-Path)

./configure --prefix=armv7s --disable-ffmpeg --disable-ffplay --disable-ffprobe --disable-ffserver --enable-avresample --enable-cross-compile --sysroot="/Applications/XCode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS7.0.sdk" --target-os=darwin --cc="/Applications/XCode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/clang" --extra-cflags="-arch armv7s -mfpu=neon -miphoneos-version-min=7.0" --extra-ldflags="-arch armv7s -isysroot /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS7.0.sdk -miphoneos-version-min=7.0" --arch=arm --cpu=cortex-a9 --enable-pic

EDIT: Download my script and run from: Installing ffmpeg ios libraries armv7, armv7s, i386 and universal on Mac with 10.8

this probably is what you looking for. Get their build script and study. Change the SDK to your 7.0. It'll compile, at least for me on my Xcode5.

UPDATE: search for ffmpeg4ios.
