第一种方案是Libssh2/libssh1这两种方案，需要个人开发很多功能。
第二种使用已经安卓化的应用：https://github.com/CFM880/simplesshd,可搭配

cef的Qt的封装库及webrtc的测试
1.webrtc已经在cef3.x中支持。
2.由于cef的编译复杂性，有一些第三方机构专门编译一些全功能的二进制库，并提供了相应的例子，很方便地直接引入到第三方应用中。
3.在window中，简述其编译测试如下：
A-首先下载cef的库文件。下载地址如下：
http://opensource.spotify.com/cefbuilds/index.html【记住要下载32位的版本，不要下载64位的】
下载完成，先阅读其CMakeLists.txt文件，它说明了在各个平台该如何二次编译，如window的编译截图如下：
注：————–一定要用cmake -G “Visual Studio 14″【也即是vs2015,社区版就可以了编译了】的命令，令其生成工程vc的工程文件。———
注：————–不要用cmake的gui方式生成工程，因为可能会失败，而产生困扰——————————-
4.用vs2015打开工程，选择全编译。
5.调试cefclient工程，在调试器中添加–enable-media-stream选项。
6.打开webrtc的测试页面如下：
https://webrtc.github.io/samples/
7.截图如下：经验检，摄像头及声音都正常。
8.

有人针对这场景写了一个QT的封装库，可以方便直接被Qt使用,在github随便搜索的结果有如下，可以逐个测试。
