在Mac 10.8上安装ffmpeg ios库armv7、armv7s、i386和universal

如何在Mac with 10.8上安装最新的ffmpeg ios库armv7、armv7s、i386和universal？

几天后，我为此次安装做了逐步说明：

FFmpeg构建说明MAC 10.8或更高版本

复制ffmpeg-2.0.tar.bz2（，）并解压缩到Documents文件夹

---

确保在Xcode>下有最新的命令行工具；偏好>；下载>；组成部分

安装气体预处理器

点击ZIP图标下载

将gas-preprocessor.pl复制到/usr/bin目录

通过将权限设置为读取和写入所有，更改gas-preprocessor.pl的权限

从10.8版开始的xcrun中的错误

打开端子并粘贴以下命令，然后按enter键：

export DEVELOPER_DIR="/Applications/Xcode.app/Contents/Developer/"

mkdir armv7
mkdir armv7s
mkdir i386
mkdir -p universal/lib

./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/iPhoneOS6.1.sdk" --target-os=darwin --cc="/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/gcc" --extra-cflags="-arch armv7s -mfpu=neon -miphoneos-version-min=6.1" --extra-ldflags="-arch armv7s -isysroot /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS6.1.sdk -miphoneos-version-min=6.1" --arch=arm --cpu=cortex-a9 --enable-pic

cd ../..

将cd粘贴到ffmpeg-2文件夹，并粘贴到以下命令中，然后按enter键：

export DEVELOPER_DIR="/Applications/Xcode.app/Contents/Developer/"

要在以下命令中配置armv7s库粘贴，请按enter键：

export DEVELOPER_DIR="/Applications/Xcode.app/Contents/Developer/"

mkdir armv7

cd -
done
cd ../..

（注意与上面相同的规则：如果配置失败，请转到 Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/ 如果没有更改，请确保sdk文件夹为iPhoneOS6.1.sdk config命令以反映iPhoneOSx.x.sdk并更改所有目标 至x.x）

要构建和安装armv7s库，请粘贴以下命令并按enter键：

export DEVELOPER_DIR="/Applications/Xcode.app/Contents/Developer/"

mkdir armv7
mkdir armv7s
mkdir i386
mkdir -p universal/lib

./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/iPhoneOS6.1.sdk" --target-os=darwin --cc="/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/gcc" --extra-cflags="-arch armv7s -mfpu=neon -miphoneos-version-min=6.1" --extra-ldflags="-arch armv7s -isysroot /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS6.1.sdk -miphoneos-version-min=6.1" --arch=arm --cpu=cortex-a9 --enable-pic

done
cd ../..

要配置i386（以便模拟器工作），请粘贴以下命令并按enter键：

export DEVELOPER_DIR="/Applications/Xcode.app/Contents/Developer/"

mkdir armv7
mkdir armv7s
mkdir i386
mkdir -p universal/lib

./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/iPhoneOS6.1.sdk" --target-os=darwin --cc="/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/gcc" --extra-cflags="-arch armv7s -mfpu=neon -miphoneos-version-min=6.1" --extra-ldflags="-arch armv7s -isysroot /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS6.1.sdk -miphoneos-version-min=6.1" --arch=arm --cpu=cortex-a9 --enable-pic

echo "Universal $file created."
cd -
done
cd ../..

（注意：这与前两个配置命令不同。） 命令，如果向上箭头指向这些命令，则将失败）

要构建和安装i386库，请粘贴以下命令并按enter键：

export DEVELOPER_DIR="/Applications/Xcode.app/Contents/Developer/"

mkdir armv7

要使通用库（即添加到xcode的库）粘贴到以下命令中，请按enter键：

export DEVELOPER_DIR="/Applications/Xcode.app/Contents/Developer/"

mkdir armv7
mkdir armv7s
mkdir i386

支持iOS7和XCode5的通用ffmpeg库：

---

确保在Xcode>下有最新的命令行工具；偏好>；下载>；组成部分

安装气体预处理器

点击ZIP图标下载

将gas-preprocessor.pl复制到/usr/bin目录

通过将权限设置为读取和写入所有，更改gas-preprocessor.pl的权限

从以下位置下载我的shell脚本：

运行

sh build ffmpeg.sh

---

我需要arm64支持，这个脚本对我很有用：

使用

适用于iOS 64位和模拟器体系结构。然后将“fat”目录中的内容复制到您的Xcode项目中

我对脚本所做的唯一修改是取消对这一行的注释：

CONFIGURE_FLAGS="$CONFIGURE_FLAGS --enable-avresample"

编译libavresample库

---

编辑：它不适用于armv7和armv7s，但使用的是iOS 7.1 SDK。如果我找到了解决方案，我将在这里发布。

用于构建您可以使用的ffmpeg iOS库

下载ffmpeg源代码

下载

打开终端并运行导出FFSRC=/path/to/ffmpeg

转到

构建\u ffmpeg

文件夹并运行：

/ios.sh

成功构建后，结果将显示在

sdk ios

文件夹中

在Xcode项目中添加include文件夹和lib文件夹

---

这将使它更容易阅读。您可以突出显示文本并点击ctrl+k或command+k（我想），或者单击文本框上方的代码按钮（看起来像

{}

）。您可以添加对iOS7的支持吗？我尝试在ffmpeg2.2和gas预处理器中使用上述说明，但是，我只得到了静态libs文件（我可以从中创建可执行文件吗？），我哪里都没看到ffmpeg。。。？我应该从配置中删除禁用ffmpeg吗？你能详细说明每个参数的含义吗？如果我只想从一种音频文件格式转换成另一种格式？（或将立体声合并到单声道？）我应该使用什么设置来配置上述脚本？我希望二进制输出尽可能小……太棒了，我为此浪费了很多时间DAlso请检查运行此脚本的目录路径是否不包含空格。我收到此错误

/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/gcc无法创建可执行文件。C编译器测试失败。

GCC在Xcode5中明显贬值。我很不确定下一步该怎么办。请确保您在Xcode>下拥有最新的命令行工具；偏好>；下载>；Component我也收到了Joseph Toronto的问题，我似乎正在使用最新的5.1.1命令行工具。我可以从4.x和5.x中进行选择。请参考这篇文章，它将对您有所帮助：您不应该将armv7和armv7s添加到命令行脚本中吗？
