VLC多媒体播放器(英语:VLC media player,最初为VideoLAN Client,是VideoLAN计划的开放源代码多媒体播放器。)支持众多音频与视频解码器及文件格式,并支持DVD影音光盘,VCD影音光盘及各类流协议,它是一个开源并且支持多种平台。
官网:https://wiki.videolan.org/AndroidCompile#Get_VLC_Source
环境:
宿主机:Windows XP
虚拟机:VirtualBox-4.3.12-93733-Win.exe
虚拟机系统:ubuntu14.04
环境搭建要求:
在Linux系统上,我安装的是Ubuntu14.04
需要安装的工具:
apache-ant (or ant), autoconf, automake, autopoint, cmake, gawk (or nawk), gcc, g++, libtool, git,
m4, patch, pkg-config, ragel, subversion, unzip.
提示:
1、如果是编译Android-x86设备,应该安装yasm
一、Android SDK
1.创建一个名为android_tools的目录
2.到官网上下载最新的SDK http://developer.android.com/sdk/index.html
3.解压到android目录下
4.运行:tools/android (也可以运行: "tools/android update sdk -u -t platform,platform-tool,extra")
5.在tool目录,安装"SDK Platform Android 4.3, API 18",根据提示操作
注:VLC的工程属性文件project.properties的target=android-18一定是已经安装的,否则会报问题三:
二、Android NDK
1.确保SDK已经安装成功,NDK要r9 版本以上的,因为在compile.sh文件中已经配置好了,如果版本过低会提示:You need the NDKv9 or later
2.下载NDK for Linux http://developer.android.com/intl/zh-cn/tools/sdk/ndk/index.html
3.解压到android_tools目录下,确保和SDK放在同一目录下
注意安装SDK和NDK时一定要注意机器是64还是32位,下载对应的版本安装,否则会有一些莫名其妙的问题
SDK和NDK的安装,都是解压的当前目录android_tools下
dzt@dzt-VirtualBox:~/android_tools$ sudo tar -xvf /mnt/shared/android-ndk-r9d-linux-x86.tar.bz2
dzt@dzt-VirtualBox:~/android_tools$ sudo unzip /mnt/shared/adt-bundle-linux-x86-20140702.zip
三、配置环境变量
在~/.bashrc最后添加 sudo gedit ~/.bashrc
export ANDROID_SDK=/home/dzt/android_tools/adt-bundle-linux-x86_64-20140321/sdk
export ANDROID_NDK=/home/dzt/android_tools/android-ndk-r9d
export PATH=$PATH:$ANDROID_SDK/platform-tools:$ANDROID_SDK/tools
根据实际安装路径写
设置环境变量等效:
dzt@dzt-VirtualBox:~/android_tools$ sudo source ~/.bashrc
Devices在命令行中指定设备,这个不是在文件中配置的,每次编译后退出再进来都需要重新设置
root@dzt-VirtualBox:/home/dzt/android_vlc/android# export ANDROID_ABI=armeabi
root@dzt-VirtualBox:/home/dzt/android_vlc/android# export NO_FPU=1
四、编译
1.Get VLC Source
在之前创建的android目录下运行以下命令
git clone git://git.videolan.org/vlc-ports/android.git
2.Compile
运行:sh compile.sh
root@dzt-VirtualBox:/home/dzt/android_vlc/android# sh compile.sh
For an ARMv6 device without FPU:
$ export NO_FPU=1
For an ARMv5 device:
$ export NO_ARMV6=1
If you plan to use a release build, run ‘compile.sh release‘

Building tools
我下载的是r9d
需要更新compile.sh文件,如果NDK版本过低或过高会提示:You need the NDKv9 or later
此时就需要修改compile.sh文件
root@dzt-VirtualBox:/home/dzt/android_vlc/android# gedit compile.sh
# try to detect NDK version
REL=$(grep -o ‘^r[0-9]*.*‘ $ANDROID_NDK/RELEASE.TXT 2>/dev/null|cut -b2-)
echo $REL //打印出版本
case "$REL" in
9|9*) #主要修改这一行
GCCVER=4.8
CXXSTL="/"${GCCVER}
;;
7|8|*)
echo "You need the NDKv9 or later"
exit 1
;;

相关库的下载:http://download.videolan.org/pub/contrib/有可能会进不去,我是用了VPN
依赖的一些库,这些库在编译过程中会进行下载,但有可能会下载失败,此时就需要手动去下载,拷贝到这个目录下。

由于我的机器的32位的,我用了64位的软件,把SDK和NDK换成32位的就没这个问题了。

我按照上面的步骤重新下载一遍就没有报这个错误。
我之前是
第一步git clone git://git.videolan.org/vlc-ports/android.git
再做后面的事,所以才报了这个问题,我全部删除后再按上面的步骤执行相当顺利。

因为我没有安装"android-19"的SDK,
解决办法有两种
1、修改工程属性文件vlc-android/project.properties文件
# This file is automatically generated by Android Tools.
# Do not modify this file -- YOUR CHANGES WILL BE ERASED!
#
# This file must be checked in Version Control Systems.
#
# To customize properties used by the Ant build system use,
# "ant.properties", and override values to adapt the script to your
# project structure.
# Project target.
target=android-18
android.library.reference.1=../java-libs/appcompat
android.library.reference.2=../java-libs/SlidingMenu
android.library.reference.3=../java-libs/WheelView
2、安装"android-19"SDK即可,运行以下命令
root@dzt-VirtualBox:/home/dzt/android_tools/adt-bundle-linux-x86-20140702/sdk# tools/android
出现如下画面,下载你需要的SDK即可,但不一定都能下载,因为最近连google都无法连上,你懂的
总结:
在编译的过程中碰到很多问题,有问题可以先百度一下,看别人有没有碰到类似的情况,一般都能在网上找到答案,需要具体问题具体分析,如果找不到要想下自己执行的步骤跟官网上的是否一致;
实在没办法就按步骤多试几遍也许能行。
