参考了这篇博文：http://blog.csdn.net/madongchunqiu/article/details/7625083，根据后面的问答修改了一些脚本内容，以及编译时遇到的问题说明
只针对真机编译，前几步跟上面博文一样：
1.到http://www.videolan.org/vlc/download-ios.html 下载3个压缩文件
2. 创建目录（比如/VLC)，并将3个源代码包解压在目录内，并依次重命名为：MediaLibraryKit, MobileVLC, vlc
3.替换脚本文件内容：/VLC/vlc/extras/package/ios/build_for_iOS.sh，其中
-miphoneos-version-min我设置的是5.0，你也可以设置成5.1或6.0：
#!/bin/shset -eecho "Building libvlc for the iOS"if [ "$1" = "Simulator" ]; then PLATFORM="Simulator" TARGET="i686-apple-darwin10" ARCH="i386"else PLATFORM="OS" TARGET="arm-apple-darwin10" ARCH="armv7" OPTIM="-mno-thumb"fiTHIS_SCRIPT_PATH=`pwd`/$0pushd `dirname $0`/../../..VLCROOT=`pwd` # Let's make sure VLCROOT is an absolute pathpopdDEVROOT="/Applications/Xcode.app/Contents/Developer/Platforms/iPhone${PLATFORM}.platform/Developer"IOS_SDK_ROOT="${DEVROOT}/SDKs/iPhone${PLATFORM}6.0.sdk"BUILDDIR=${VLCROOT}/build-ios-${PLATFORM}PREFIX=${VLCROOT}/install-ios-${PLATFORM}IOS_GAS_PREPROCESSOR="${VLCROOT}/extras/package/ios/resources/gas-preprocessor.pl"export AR="${DEVROOT}/usr/bin/ar"export RANLIB="${DEVROOT}/usr/bin/ranlib"export CFLAGS="-isysroot ${IOS_SDK_ROOT} -arch ${ARCH} -miphoneos-version-min=5.0 ${OPTIM}"export OBJCFLAGS="${CFLAGS}"if [ "$PLATFORM" = "Simulator" ]; then # Use the new ABI on simulator, else we can't build export OBJCFLAGS="-fobjc-abi-version=2 -fobjc-legacy-dispatch ${OBJCFLAGS}"fiexport CPPFLAGS="${CFLAGS}"export CXXFLAGS="${CFLAGS}"export CPP="${DEVROOT}/usr/bin/llvm-cpp-4.2"export CXXCPP="${DEVROOT}/usr/bin/llvm-cpp-4.2"export CC="${DEVROOT}/usr/bin/llvm-gcc-4.2"export OBJC="${DEVROOT}/usr/bin/llvm-gcc-4.2"export CXX="${DEVROOT}/usr/bin/llvm-g++-4.2"export LD="${DEVROOT}/usr/bin/ld"export STRIP="${DEVROOT}/usr/bin/strip"if [ "$PLATFORM" = "OS" ]; then export LDFLAGS="-L${IOS_SDK_ROOT}/usr/lib -L${IOS_SDK_ROOT}/usr/lib/system -arch ${ARCH}"else export LDFLAGS="-syslibroot=${IOS_SDK_ROOT}/ -arch ${ARCH}"fiexport PATH="/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/X11/bin:${VLCROOT}/extras/contrib/build/bin:${VLCROOT}/extras/package/ios/resources"echo "Boostraping contribs"pushd ${VLCROOT}/extras/contrib# contains gas-processor.plexport PATH=$PATH:${VLCROOT}/extras/package/ios/resources# The contrib will read the followingexport IOS_SDK_ROOTecho "Building contrib for iOS"./bootstrap ${TARGET} iosmake srcecho "Building contrib for current host"./bootstrapmakepopdif [ "$PLATFORM" = "OS" ]; then export AS="${IOS_GAS_PREPROCESSOR} ${CC}" export ASCPP="${IOS_GAS_PREPROCESSOR} ${CC}"else export AS="${DEVROOT}/usr/bin/as" export ASCPP="${DEVROOT}/usr/bin/as"fiecho "Bootstraping vlc"if !

5. 修改Makefile文件，禁用汇编，该文件位于：/VLC/vlc/extras/contrib/src目录下
改动方式：搜寻关键字“FFMPEGCONF”，FFMPEGCONF =改为FFMPEGCONF = --disable-asm
这步其实相当纠结，虽然最终编译出可运行的app，但效率实在不敢恭维，我试过1G以上的rmvb和avi文件，均无法正常播放；郁闷。
后来根据这篇文章https://github.com/yuvi/gas-preprocessor/issues/16最后提到的下载这个https://github.com/xbmc/xbmc/tree/master/tools/darwin/depends/gas-preprocessor，并替换vlc/extras/package/ios/resources下的同名文件，尝试编译，仍然会有错；
再后来我又替换了vlc/extras/contrib/src-arm-apple-darwin10-ios/src/ffmpeg/libavutil/arm目录下的intmath.h和intreadwrite.h2个头文件（其实脚本执行最先会去svn地址checkout ffmpeg，我不知道这个ffmpeg的svn内容到底是何时版本的，因为我单独编译过ffmpeg，网上的教程是git clone git://source.ffmpeg.org/ffmpeg.git这个地址，于是我直接从git clone这来的同目录下的头文件去替换了vlc里的）；这样就不需要修改Makefile文件了，但编译出来运行效果还是不理想，这一步还望高人求解，如何不disable-asm而编译成功？
6. 为了编译libdvbpsi库，稍稍修改iOS SDK的源文件。这是因为编译时会报错说找不到"i386/limits.h"，所以需要把这个文件拷贝到他的搜寻目录中去。
- a) 找到目录：/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS5.0.sdk/usr/include
- b) 在其中新建目录：i386
- c) 全局搜索某个i386目录下的limits.h和_limits.h文件，并将搜索到的这两个文件拷贝入刚才创建的目录中。
7.替换VLC/vlc/extras/contrib里的bootstrap内容如下，mac为10.8系统的请把其中10.7的文本都替换为10.8：

cd /VLC/vlc/extras/package/ios （这里要自己改成绝对路径）
./build_for_iOS.sh
该脚本执行会遇到2处错误：
1."/usr/bin/curl" -L -O http://live555.com/liveMedia/public/live555-latest.tar.gz1.
make[1]: *** [live] Error 1
make: *** [using-src] Error 2
这个错误不管，重新执行./build_for_iOS.sh又会继续编译。
2."/usr/bin/curl" -L -O http://downloads.videolan.org/pub/videolan/testing/contrib/contrib-macosx-i386-34.tar.bz2
(cd tmp && tar jxvf ../contrib-macosx-i386-34.tar.bz2)
tar: Unrecognized archive format
tar: Error exit delayed from previous errors.
对于这个错误，先进入/vlc/extras/contrib目录，删除temp和/host/i686-apple-darwin11/ 下darwin这两个目录，然后手动去下载http://downloads.videolan.org/pub/videolan/contrib/contrib-macosx-i386-34.tar.bz2（多谢下面评论的兄弟的提醒），替换该目录下的同名压缩包；该包正常大小为24.4M，而错误下载包只有168k；然后重新执行./build_for_iOS.sh，这下应该一切编译OK9.继续执行命令：

10.进入VLC/MobileVLC目录，打开项目文件，Bundle identifier改成自己的，连接真机编译运行OK，拷贝几个媒体文件到Documents里，启动后就有文件列表了。
