8 years ago 问题找到了，我安装了两个xcode,默认的是xcode8，可以在编译ffmpeg时候用的是xcode8，而我打开demo工程用的是xcode7.3，导致链接出错，使用xcode8就可以了

我是按如下进行操作的： git clone https://github.com/Bilibili/ijkplayer.git ijkplayer-ios cd ijkplayer-ios git checkout -B latest k0.6.2
./init-ios.sh
cd ios ./compile-ffmpeg.sh clean ./compile-ffmpeg.sh all
然后，用xcode打开的ijkplayer-ios/ios/IJKMediaDemo/IJKMediaDemo.xcodeproj,编译就出现了如上问题！
