live555是个流媒体C++开源库,VLC的Meida Player就使用了它的API完成的RTSP客户端,由于VLC的SDK没有提供相关record流到视频文件的API,所以我想用过live555的例子学习,但是live555它不自带二进制的发布,必须自己编译。
编译live555:

这个是打好的VS2013的包,编译live555的工程:

live555的OpenRTSP例子程序可以打开接收流,并且进行存储为视频文件。当然听说FFMPEG也可以,但是我看了些例子,比较复杂,所以不看了。而且VLC也是使用live555来做的。所以就打算研究这个。
我是用VS2013编译的,但是照链接文章的方法,出现了的错误,原来是在VS2013安装的时候,把ntwin32.mak拷贝到VC的include目录下失败了,所以就没有,是从我的C:\Program Files (x86)\Microsoft SDKs\Windows\v7.1A\Include这个目录拷贝的,这里面有ntwin32.mak 和win32.mak,这两个都需要。拷贝到VS2013的安装目录的VC目录的include目录下。编译就不会出错了。但是这个过程中还有一个错误:就是打开msvcirt.lib 这个库错误,心想,这是啥库啊,都没有听过,其实这个msvcirt.lib 是老版本的名字,不是新的,VS2013的SDK当然是新的了,所以要用CRT,msvcrt.lib 这个运行时库,原来是win32config这个文件里面这个域LINK_OPTS_0 的库名字写错了,把它改成msvcrt.lib 就行了。然后就完美成功生成相关lib了。唉,开源的东西真心蛋疼啊,windows上编译又不友好。
照上面的方法,默认编译出来的是x86的,需要编译成x64的。
就需要在VS2013的VS tools里面找到x64 Native Common Prompt的命令行工具进行编译。做个好人,还是把x64相关的win32config修改贴上来吧:
