android使用socket實現實時視頻

該視頻實現是基於TCP/IP協議的Socket(客戶端)和ServerSocket(服務端)類，發送視頻也就是不間斷的發送圖片。具體以下：

PC服務端：socketService類開啓服務及監聽，線程類TheadServer處理socket鏈接，並調用另一個線程類ThreadClient發送圖片到到另一臺手機上

視頻發送端：MainVideoActivity 爲顯示界面，子線程ClientThread處理圖片併發送到服務器

視頻接受端：MainActivity爲顯示界面，子線程RevImageThread爲接受服務端發送過來的圖片

PC端 socketService類：

package com.socket;
import java.io.IOException;
import java.net.ServerSocket;
import java.net.Socket;

public class socketService {

/**
* @param args
* @throws IOException
*/

System.out.println("begin");

while(true){

new Thread(new TheadServer(ss)).start();
}
}
}
