快速用VLC的SDK开发RTSP流教程

http://www.cnblogs.com/MikeZhang/tag/%E8%A7%86%E9%A2%91%E6%8A%80%E6%9C%AF/

使用VLC的SDK开发播放器，不管是播放文件还是RTSP流都是相当简单的事，只需要调用几个简单的函数就可以实现播放了，甚至你连窗口都可以不建，SDK会自动创建窗口。

你需要准备的是安装VLC，可以到官网上下载最新版本，直接安装之后在程序目录有一个APP/SDK/里面的include,lib复制出来，另外 有一个插件目录plugins,也要在发布程序时复制到程序根目录就可以了

vlc-sdk-file需要的文件

通过这个代码片断你应该了解如何调用VLC的SDK来实现简单的播放器开发了。
