vlc-android 源码下载及主要编译过程可以参考vlc官方微博，地址如下:

在vlc-android编译过程中，我遇到了很多问题，在此记录一下：
1 vlc依赖库a52dec编译时报错，如下:
mkdir -p – /home/chen/workspace/vlc-android/vlc/contrib/x86_64-linux-android/share/aclocal && cd a52dec && autoreconf -fiv -I/home/chen/workspace/vlc-android/vlc/contrib/x86_64-linux-android/share/aclocal
autoreconf: Entering directory `.’
autoreconf: configure.in: not using Gettext
autoreconf: running: aclocal -I /home/chen/workspace/vlc-android/vlc/contrib/x86_64-linux-android/share/aclocal –force
aclocal: warning: autoconf input should be named ‘configure.ac’, not ‘configure.in’
autoreconf: configure.in: tracing

configure.in:74: error: possibly undefined macro: AC_DISABLE_SHARED
If this token and others are legitimate, please use m4_pattern_allow.
See the Autoconf documentation.
configure.in:75: error: possibly undefined macro: AC_LIBTOOL_WIN32_DLL
configure.in:76: error: possibly undefined macro: AC_PROG_LIBTOOL
autoreconf: /home/chen/workspace/vlc-android/vlc/extras/tools/build/bin/autoconf failed with exit status: 1
make: * [.a52] Error 1
contribs: make failed
解决办法：
apt-get install libtool 安装libtool，若问题还未得到解决，进到 vlc/contrib/contrib-android-x86_64-linux-android(注：因为我指定的平台是x86_64所以是这个目录，如果制定其他平台，则路径替换为 vlc/contrib/contrib-android-host-linux-android)目录，打开Makefile，找到
PATH :=
export PATH
注释掉这两行，然后在当前目录下执行
export PATH=$PATH:/opt/android-ndk-r12b/toolchains/x86_64-4.9/prebuilt/linux-x86_64/bin
make -j1
make install
中间可能遇到遇到一些错误，大部分都是需要升级或安装一些工具，依赖库等
编译完成后，回到vlc-android目录下，重新执行
sh compile.sh -a x86_64
