使用https://github.com/kewlbear/FFmpeg-iOS-build-script的脚本一键编译ffmpeg。
出现
building arm64...
xcrun -sdk iphoneos clang is unable to create an executable file.
输入
xcodebuild -showsdks
如果出现
error: tool 'xcodebuild' requires Xcode, but active developer directory '/Library/Developer/CommandLineTools' is a command line tools instance
说明你的 Xcode命令行工具路径错误
使用
sudo xcode-select --switch /Applications/Xcode.app/Contents/Developer/
问题解决
