四、总结

有个IPC的项目有用到live555，简单编译了一下live555的动态库，作为笔记存用，因为也没碰到什么难点，有问题可以联系我

一、Live555简绍

Live555作为一个经典的流媒体开源框架，相信如果你要用到，肯定也有初步了解，我的项目中用到他的RTSP Server。一起来看看它的支持：

The “LIVE555 Media Server” is a complete RTSP server application. It can stream several kinds of media file (which must be stored in the current working directory - i.e., the directory from which you launch the application - or a subdirectory.):
- A MPEG Transport Stream file (with file name suffix “.ts”)
- A Matroska or WebM file (with filename suffix “.mkv” or “.webm”)
- An Ogg file (with filename suffix “.ogg”, “ogv”, or “.opus”)
- A MPEG-1 or 2 Program Stream file (with file name suffix “.mpg”)
- A MPEG-4 Video Elementary Stream file (with file name suffix “.m4e”)
- A H.264 Video Elementary Stream file (with file name suffix “.264”)
- A H.265 Video Elementary Stream file (with file name suffix “.265”)
- A VOB video+audio file (with file name suffix “.vob”)
- A DV video file (with file name suffix “.dv”)
- A MPEG-1 or 2 (including layer III - i.e., ‘MP3’) audio file (with file name suffix “.mp3”)
- A WAV (PCM) audio file (with file name suffix “.wav”)
- An AMR audio file (with file name suffix “.amr”)
- An AC-3 audio file (with file name suffix “.ac3”)
- An AAC (ADTS format) audio file (with file name suffix “.aac”)
  上面死它支持流的类型，它能同时传输多路流，支持VLC和RTSP Client预览流媒体
它对应的目录（中间还包含其他目录，包括win和linux编译环境和脚本，我们用不到删除即可）：
- BasicUsageEnvironment UsageEnvironment define
- groupsock 包含网络和socket相关
- liveMedia 核心功能，对接流媒体编码器等
- mediaServer 媒体server
- proxyServer 代理server
- UsageEnvironment 都是些待实现的抽象基础类，构成一些基础架构
- testProgs 列举使用UsageEnvironment实现的一些简单程序

二、编译live555

下载：http://www.live555.com/liveMedia/public/
```
 选择live555-latest.tar.gz
```
删除用不到的文件，如win和linux编译环境和脚本

三、解决报错

错误：

GroupsockHelper.cpp:575:23: error: request for member ‘s_addr’ in ‘imr.ip_mreq_source::imr_multiaddr’, which is of non-class type ‘__be32 {aka unsigned int}’
imr.imr_multiaddr.s_addr = groupAddress;

查看代码：

  ----------->其中定义的NDK版本
  #define ANDROID_OLD_NDK __NDK_MAJOR__ < 17


  ----------->575报错的代码：其中判断了NDK编版本。我关注自己版本以下即可，注释即可，后面的错误同理

  Boolean socketJoinGroupSSM(UsageEnvironment& env, int socket,
  	   netAddressBits groupAddress,
  	   netAddressBits sourceFilterAddr) {
  	  if (!IsMulticastAddress(groupAddress)) return True; // ignore this case
  	
  	  struct ip_mreq_source imr;
  	#if ANDROID_OLD_NDK
  	    imr.imr_multiaddr = groupAddress;
  	    imr.imr_sourceaddr = sourceFilterAddr;
  	    imr.imr_interface = ReceivingInterfaceAddr;
  	#else
  	   // imr.imr_multiaddr.s_addr = groupAddress;
  	   // imr.imr_sourceaddr.s_addr = sourceFilterAddr;
  	   // imr.imr_interface.s_addr = ReceivingInterfaceAddr;
  	#endif
  	  if (setsockopt(socket, IPPROTO_IP, IP_ADD_SOURCE_MEMBERSHIP,
  			 (const char*)&imr, sizeof (struct ip_mreq_source)) < 0) {
  	    socketErr(env, "setsockopt(IP_ADD_SOURCE_MEMBERSHIP) error: ");
  	    return False;
  	  }
  	
  	  clearMulticastAllSocketOption(socket);
  	
  	  return True;
  	}

四、总结

我的NDK版本是r14b,android api=8，顺利编译完成了，live555是个很成熟的库，网上也有许多的博客和代码，基本不存在很多编译难题，如果碰到问题，可以从源码中找答案，大多数是编译环境或者宏定义判断导致。只有认真排查，很快就能解决
