iphone x264 庫編譯方法

首先到http://www.videolan.org/developers/x264.html下載x264的庫，然後解壓。

開啟shell，進入x264的目錄，執行如下語句

CC=/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/gcc ./configure --host=arm-apple-darwin --sysroot=/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS6.1.sdk
--prefix='dist' --extra-cflags='-arch armv7s' --extra-ldflags='-arch armv7s -L/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS6.1.sdk/usr/lib/system' --enable-pic

然後make，libx264.a就出來啦。如果無法執行，請將語句中的6.1.sdk替換成你電腦裡面有的sdk。

注意:

    CC=/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/gcc

    請確保，路徑正確。
