Android 手机采集摄像头视频 socket 视频传输实时传播

这里搜集了两种实现Android 手机采集摄像头视频 socket 视频传输实时传播的方法，两种都可以使用。

第一种如下：

1.通过客户端socket请求，服务端接受到请求后，获取socket的输出流对象outs。  
2.服务端通过Camera的setPreviewCallback方法回调采集摄像头视频数据，将一张张图片数据数据压缩，发送到客户端，因为是图片，需要在图片开头加个标记，然后指定数据长度发送。  
3.客户端接收数据，根据数据开头标记，以及数据的长度，接收数据，按一张张图片的形式，采用handle更新imageview。  
主要代码：

服务端代码：

第二种方法：

该视频实现是基于TCP/IP协议的Socket(客户端)和ServerSocket(服务端)类，发送视频也就是不间断的发送图片。具体如下：

PC服务端：socketService类开启服务及监听，线程类TheadServer处理socket连接，并调用另外一个线程类ThreadClient发送图片到到另外一台手机上

视频发送端：MainVideoActivity 为显示界面，子线程ClientThread处理图片并发送到服务器

视频接受端：MainActivity为显示界面，子线程RevImageThread为接受服务端发送过来的图片
