Android 多媒体框架 OpenCore（PacketVideo）介绍

核心提示：* libopencoreplayer.so：OpenCore的Player库* libopencoreauthor.so：OpenCore的Author库* libopencorertspreg.so：RTSP注册库* libopencorertsp.so：RTSP功能实现库OpenCore的各个库之间具有如下的关系

* libopencoreplayer.so：OpenCore的Player库

* libopencoreauthor.so：OpenCore的Author库

* libopencorertspreg.so：RTSP注册库

* libopencorertsp.so：RTSP功能实现库

OpenCore的各个库之间具有如下的关系：

libopencorecommon.so是所有的库的依赖库，提供了公共的功能;

libopencoreplayer.so和libopencoreauthor.so是两个并立的库，分别用于回放和记录，而且这两个库是OpenCore对外的接口库;

libopencorenet_support.so提供网络支持的功能;

一些功能以插件(Plug-In)的方式放入Player中使用，每个功能使用两个库，一个实现具体功能，一个用于注册。

2.libopencorecommon.so库的结构

libopencorecommon.so是整个OpenCore的核心库，它的编译控制的文件的路径为pvcommon/Android.mk，这个文件使用递归的方式寻找子文件：
