BlackOnvif: 测试可用;实现的功能比较少;该项目是基于Android 通过onvif协议实现搜索设备以及获取设备信息

# BlackOnvif
Android onvif 搜索设备并获取信息<br>
此项目是基于Android 通过onvif协议实现搜索设备以及获取设备信息，相关blog:http://blog.csdn.net/a512337862/article/details/79281648

# 思路

最近，在接触onvif协议在Android端的实现。抓了无数的包，踩了无数的坑之后，利用取巧的方式也终于实现部分的功能，
主要是搜索IPC设备，获取IPC设备的一些信息：rtsp地址，音视频编解码信息，云台信息等。关于onvif协议请自行百度。

# 思路
这里主要是将一些需要发送的关键指令以文件的形式保存在assets中，需要时直接从assets中读取指定的文件，
然后将一些关键的字符填充进去发送给服务器即可。项目的流程如下：

- 1.发送广播包搜索局域网内的IPC。
- 2.通过IPC设备的serviceUrl获取IPC的能力集。
- 3.获取IPC的Profiles
- 4.获取IPC每个Profile的rtsp

# BX笔记

## 刚开始搜索到设备,但是设备的信url为nul，原来是缓存的数组长度不够导致
