##### 简介 #####

Vlc for android是一款开源安卓播放器，具备播放多媒体文件、光盘、设备以及网络流媒体协议等功能，支持ARMv7 CPU或一个x86 CPU的设备，所有播放控制特性都已经开发完整。

下面将介绍如何获取代码、编译、vlc原理、缩小延迟、添加截图和录制视频、多路播放等。

##### 详解 #####

###### 1、获取代码 ######

官网源码下载：http://mirror.us.leaseweb[.NET][]/videolan/

[Git][]获取：clone from [git][Git]://git.videolan.org/vlc-ports/[Android][].git

补丁：https://patches.videolan.org/

###### 2、编译 ######

1、搭配环境  
AndroidSDK：adt-bundle-[Linux][]\-x86-20130522  
JDK：jdk-7u25-[linux][Linux]\-i586  
NDK：[android][Android]\-ndk-r8e-linux-x86

2、安装工具  
apt-get install gcc  
apt-get install g++  
apt-get build-dep vlc   
apt-get install git   
apt-get install wget   
apt-get install autoconf  
apt-get install libtool  
apt-get install subversion   
apt-get install cmake  
apt-get install ant

3、配置信息

export ANDROID\_NDK=/home/mythou/android-dev/android-ndk-r8e  
export NDKR5C=/home/mythou/ndkr5c  
export NDKR6B=/home/mythou/ndkr6b  
PATH=$PATH:$NDKR6B:$ANDROID\_NDK  
  
export ANDROID\_ABI=armeabi-v7a  
  
export JAVA\_HOME=/home/mythou/android-dev/jdk/jdk1.7.0\_25  
export JRE\_HOME=/home/mythou/android-dev/jdk/jdk1.7.0\_25/jre  
export CLASSPATH=.:$CLASSPATH:$JAVA\_HOME/lib:$JAVA\_HOME/jre/lib  
export ANT\_HOME=/home/mythou/android-dev/apache-ant-1.8.0  
export PATH=$JAVA\_HOME/bin:$JAVA\_HOME/jre/bin:$PATH:$HOME/bin:$ANT\_HOME  
  
export ANDROID\_SDK=/home/mythou/android-dev/adt-bundle-linux-x86-20130522/sdk  
PATH=$PATH:$ANDROID\_SDK/tools:$ANDROID\_SDK/platform-tools

4、编译

sh compile.sh   or    sh compile.sh release

5、辅助库

由于某些原因，有些库无法获得，请手动下载放入便可。

###### 3、vlc播放原理 ######

视频播放的基本步骤：  
    1、acess 访问（获取视频数据）  
    2、demux 解复用（音频、视频分离）    
    3、decode 解码（音频和视频的解码）  
    4、output 输出（音频和视频的输出（aout和vout）  
  
  
如图：

###### 4、缩小延迟 ######

修改延迟的方法有两种：1、直接用[Java][]代码实现；2、在vlc库中修改。

涉及延迟的参数有：file-caching（文件缓存）、live-caching（直播缓存）、network-caching（网络缓存）、sout-mux-caching（输出缓存）。

Java代码实现如下：

**\[java\]**  [view plain][Link 1]   [copy][Link 1]

1.  options.add(":file-caching=1500");//文件缓存  
2.  options.add(":network-caching=1500");//网络缓存  
3.    
4.  options.add(":live-caching=1500");//直播缓存  
5.  options.add(":sout-mux-caching=1500");//输出缓存  
6.    
7.  options.add(":codec=mediacodec,iomx,all");

vlc库实现如下：

查找目标文件vlc/src/libvlc-module.c  修改对应的参数

**\[java\]**  [view plain][Link 1]   [copy][Link 1]

1.  add\_integer( "file-caching", DEFAULT\_PTS\_DELAY / 3000,  
2.               CACHING\_TEXT, CACHING\_LONGTEXT, **true** )  
3.  add\_integer( "live-caching", DEFAULT\_PTS\_DELAY / 3000,  
4.               CAPTURE\_CACHING\_TEXT, CAPTURE\_CACHING\_LONGTEXT, **true** )  
5.  add\_integer( "network-caching", CLOCK\_FREQ / 3000,  
6.               NETWORK\_CACHING\_TEXT, NETWORK\_CACHING\_LONGTEXT, **true** )  
7.  add\_integer( "sout-mux-caching", 1000, SOUT\_MUX\_CACHING\_TEXT,  
8.                              SOUT\_MUX\_CACHING\_LONGTEXT, **true** )

把分母数据增大，缓存的数据就越小，延迟就减少，流畅性就减少，相反，分母数据减少，缓存的数据就越大，延迟就增加，流畅性就增加。

[测试][Link 2]结果，延迟明显减少。

###### 5、添加截图和录制视频 ######

官方已给出补丁实现截图和录制视频

1、截图

修改文件： android/configure.sh  搜索内容 \-disable-sout   并删除

修改文件：android/vlc/contrib/src/ffmpeg/rules.mak  增加\-enable-encoder=png的编码器 实现png格式截图

**\[java\]**  [view plain][Link 1]   [copy][Link 1]

1.  FFMPEGCONF += --disable-encoders --disable-muxers  
2.   改成FFMPEGCONF += --disable-encoders --enable-encoder=png --disable-muxers

源码重新编译便可

编译过程中可能会出现如下问题：

**\[java\]**  [view plain][Link 1]   [copy][Link 1]

1.  ./vlc/android/modules/.libs/libvorbis\_plugin.a(libvorbis\_plugin\_la-vorbis.o): in function OpenEncoder:../../modules/codec/vorbis.c:758: error: undefined reference to 'vorbis\_encode\_setup\_vbr‘

**\[java\]**  [view plain][Link 1]   [copy][Link 1]

1.  error: undefined reference to 'vlc\_entry\_\_access\_output\_udp'

解决方法：  
修改文件： /vlc/modules/access\_output/ Modules.am

**\[java\]**  [view plain][Link 1]   [copy][Link 1]

1.  SOURCES\_access\_output\_dummy = dummy.c    
2.      SOURCES\_access\_output\_file = file.c

23.     **if** HAVE\_GCRYPT    
24.     access\_output\_LTLIBRARIES += libaccess\_output\_livehttp\_plugin.la    
25.     endif    
26.   
27. 内容覆盖便可

相关源码添加：

在libvlcjni.c中增加函数：

**\[java\]**  [view plain][Link 1]   [copy][Link 1]

1.  **boolean** Java\_org\_videolan\_libvlc\_LibVLC\_takeSnapShot(JNIEnv \*env, jobject thiz,jint number, jstring path, jint width,jint height)    
2.  \{    
3.      jboolean isCopy;    
4.     libvlc\_media\_player\_t \*mp = getMediaPlayer(env, thiz);    
5.       /\* Get C string \*/    
6.     **const** **char**\* psz\_path = (\*env)->GetStringUTFChars(env, path, &isCopy);    
7.      
8.     **if** (mp)    
9.          **if**(libvlc\_video\_take\_snapshot(mp, (**int**)number,psz\_path , (**int**)width,(**int**)height)==0)    
10.             **return** JNI\_TRUE;    
11.    **return** JNI\_FALSE;    
12.     
13. \}

LibVlc.java中增加native函数的接口和调用方法：

**\[java\]**  [view plain][Link 1]   [copy][Link 1]

1.  **private** **native** **boolean** takeSnapShot( **int** num, String file, **int** width, **int** height);

**\[java\]**  [view plain][Link 1]   [copy][Link 1]

1.  **public** **boolean** takeSnapShot(String file, **int** width, **int** height) \{    
2.      **return** takeSnapShot(0, file, width, height);    
3.  \}

###### 6、实现多路播放 ######

使用process属性实现

##### 总结 #####

接触vlc for android 是帮助朋友完成一个外单，即实现认证播放器的封装（即添加播放网络视频的认证），传地址便可播放。

经测试vlc无法播放swf文件，为了弥补这已缺陷，准备添加swfdec到android平台以支持swf文件。

楼主您好，  
请教一个问：我下载的vlc-android怎么找不到稳重分析的关于access部分，比如里面提到的SOURCES\_access\_output\_udp = udp.c ，我在几个版本的vlc-android版本中都找不到，请问您用的那个版本？可否给我共享，非常感谢！

修改这些参数，options.add(":live-caching=1500")  
减少，会有一个问题，就是在出现卡吨后，又会回到1500的延迟。请问有遇到过吗？怎么解喔！
