android使用socket实现实时视频
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
PC端 socketService类：
package com.socket;
import java.io.IOException;
import java.net.ServerSocket;
import java.net.Socket;
public class socketService {
/**
* @param args
* @throws IOException
*/
public static void main(String[] args) throws IOException {
ServerSocket ss = new ServerSocket(3000);
System.out.println("begin");
while(true){
new Thread(new TheadServer(ss)).start();
}
}
}
TheadServer 类:
package com.socket; import java.awt.Image; import java.awt.image.BufferedImage; import java.io.IOException; import java.io.InputStream; import java.io.InputStreamReader; import java.io.OutputStream; import java.net.ServerSocket; import java.net.Socket; import javax.imageio.ImageIO; public class TheadServer implements Runnable { private Socket s = null; private BufferedImage bufferedImage; public InputStream ins; public TheadServer(ServerSocket ss ) throws IOException{ System.out.println("start thread"); this.s=ss.accept(); } @Override public void run(){ try { ins = s.getInputStream(); bufferedImage = ImageIO.read(ins); ins.close(); ThreadClient tc = new ThreadClient(bufferedImage); new Thread(tc).start(); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); }finally{ try { if(!s.isClosed()) s.close(); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } } } }
ThreadClient类:
package com.socket; import java.awt.Image; import java.awt.image.BufferedImage; import java.awt.image.RenderedImage; import java.io.ByteArrayOutputStream; import java.io.IOException; import java.io.ObjectOutputStream; import java.io.OutputStream; import java.io.Serializable; import java.net.InetSocketAddress; import java.net.Socket; import javax.imageio.ImageIO; public class ThreadClient implements Runnable , Serializable { private BufferedImage bufferedImage; public ThreadClient(BufferedImage image){ this.bufferedImage = image; } @Override public void run() { // TODO Auto-generated method stub try { Socket s = new Socket(); //接受视频端IP和端口 s.connect(new InetSocketAddress("10.0.56.234", 40000), 2000); if(s.isConnected() && !s.isClosed()){ System.out.println("Client:"+s.getRemoteSocketAddress().toString()); OutputStream oos = s.getOutputStream(); ImageIO.write(bufferedImage,"JPG",oos); oos.write("\n".getBytes()); oos.flush(); oos.close(); s.close(); } } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } } }
