iOS下编译ffmpeg

一.下载FFmpeg安装文件

下载的文件，包含 build-ffmpeg-iOS-framework.sh，build-ffmpeg-tvos.sh，build-ffmpeg.sh三个脚本。

二.编译FFmpeg

切换到FFmpeg-iOS-build-script-master目录，编译armv7，x86_64库

./build-ffmpeg.sh armv7 x86_64

building armv7...
xcrun -sdk iphoneos clang is unable to create an executable file.
C compiler test failed.

If you think configure made a mistake, make sure you are using the latest
version from Git.  If the latest version fails, report the problem to the
ffmpeg-user@ffmpeg.org mailing list or IRC #ffmpeg on irc.freenode.net.
Include the log file "ffbuild/config.log" produced by configure as this will help
solve the problem.

使用

xx@localhost FFmpeg-iOS-build-script-master % sudo xcode-select --switch /Applications/Xcode.app

配置clang编译器，重新编译即可生成armv7，x86_64库。

同理：可生成arm64，x86_64的库。
