Android(安卓)编译so文件 MP4V2

Linux系统下编译mp4v2生成Android下使用的So文件

一、需求背景

之前一直用到了mp4v2这个库，使用库进行MP4的文件录制，一直使用的是armeabi类型的so文件,后来由于AS的更新，将不再支持armeabi格式的so文件，所以才需要编译不同类型的so文件以支持项目的健壮性。而且armeabi-v7a的兼容性更好。

二、在Ubuntu下安装ndk环境

Android NDK 安装配置指南
可以根据安装指南初步编译sample工程。

三、编译mp4v2

通过第一步的sample工程的试手，我们可以知道，如果要编译工程，先需要编写对应的.mk文件。
1.android 编译mp4v2 2.0.0生成动态库
2.Android平台的Android.mk和Application.mk

第一个链接是百度上面找的，找了很多资料，很多都是参考第一个资料进行编译的。第二个资料是GITHUB上面的一个开源项目，看起来还不错，但是第二个作者将整个项目编译成了许多不同的小包。所以我需要将第一个和第二个进行整合一下。
1). 下载[2]中的项目，调整一下目录结构,在mp4v2-master目录下面新建jni目录，将其他文件都考入jni目录。
2). 将jni目录下的Android.mk里面的内容替换如下

3). 进入到mp4v2-master/jni目录运行 ndk-build命令即可进行编译
4). 如果需要编译全部类型的so文件，只需要将Application.mk文件下面 APP_ABI 修改成all即可。

编译了这么久，传上来给大家共享一下都觉得不好意思，因为ubuntu确实太难捣鼓了，为了编译这东西，又是装LINUX系统，又是学习.mk文件里面属性的作用，确实麻烦。
