用FFmpeg 5构建xCode

Question

有人知道如何用FFmpeg 5编译xCode吗？

我的配置部分：

/配置--禁用-doc--禁用-ffmpeg--禁用-ffplay--启用交叉编译--arch=arm -塔吉特-os=达尔文-启用-neon-禁用-avfilter--禁用-bsfs-启用-avresample启用-swresample启用-gpl-禁用-demuxer-启用-demuxer=rtsp-启用-demuxer=rtp-启用-demuxer=mpegts\-禁用-解码器-启用解码器=mmp3-启用decoder=mpeg2video --启用-解码器=AC3-启用-解码器=dvbsub-启用-解码器=H 264-禁用-解析器-启用-解析器=alpha 4视频-启用-解析器=alpha 4视频-使能-解析器=alpha音频-解析器=dvbsub\-禁用-muxers-禁用-encoders-禁用-过滤器\-禁用-协议-启用-协议=rtp-协议-启用-协议=tcp-禁用-协议-启用协议=tcp\-禁用-alpha-禁用-禁用-mv6\\-禁用-v62\tcp=tcp？/Applications/Xcode.app/Contents/Developer/usr/bin --as='/usr/local/bin/gas预处理程序/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--/Applications/Xcode.app/Contents/Developer/usr/bin’--sysroot=/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS7.0.sdk=‘arch armv7 -mfpu=neon -mfloat-abi=softfp’-over-ld威=‘-arch armv7 -mfpu=neon -mfloat abi=softfp -isysroot /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS7.0.sdk‘--启用-pic-禁用-bzlib

它适用于xCode 4(不同编译路径)。

错误消息：

./configure: line 3763: nm: command not found

Answer 1

./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

编辑：下载我的脚本并从：Installing ffmpeg ios libraries armv7, armv7s, i386 and universal on Mac with 10.8运行

https://github.com/ciphor/ffmpeg4ios

这可能就是你要找的。得到他们的建造脚本和学习。将SDK更改为7.0。它会编译，至少在我的Xcode5上是这样的。

更新:搜索ffmpeg4ios。
