最近要录制h264+aac的mp4视频，使用mp4v2来实现，下面就是编译的方法
1、下载源码，到官网 下载，现在最新的是mp4v2 2.0.0
2、解压下载的mp4v2-2.0.0.tar.bz2,然后进入mp4v2-2.0.0，将里面的文件以及文件夹拷贝的新创建的jni目录中，目录结构例如：/home/zhangjie/mp4v2-2.0.0/jni
3、进入jni目录，将include目录中的mp4v2文件夹拷贝出来放到jni目录下面，例如：/home/zhangjie/mp4v2-2.0.0/jni/mp4v2
4、在jni目录下创建Application.mk，内容如下：
5、创建Android.mk文件，内容如下：
