java视频流传输代码

以下是一个简单的Java视频流传输代码示例：

1. 服务端代码：

import java.io.*;
import java.net.*;

public class VideoServer {
    public static void main(String[] args) throws Exception {
        ServerSocket serverSocket = new ServerSocket(8888);
        Socket clientSocket = serverSocket.accept();
        DataInputStream dis = new DataInputStream(new BufferedInputStream(clientSocket.getInputStream()));
        DataOutputStream dos = new DataOutputStream(clientSocket.getOutputStream());
        File file = new File("video.mp4");
        FileInputStream fis = new FileInputStream(file);
        byte[] buffer = new byte[(int) file.length()];
        fis.read(buffer);
        fis.close();
        dos.writeInt(buffer.length);
        dos.write(buffer);
        dos.close();
        dis.close();
        clientSocket.close();
        serverSocket.close();
    }
}

2. 客户端代码：

import java.io.*;
import java.net.*;

public class VideoClient {
    public static void main(String[] args) throws Exception {
        Socket socket = new Socket("localhost", 8888);
        DataInputStream dis = new DataInputStream(socket.getInputStream());
        DataOutputStream dos = new DataOutputStream(new BufferedOutputStream(socket.getOutputStream()));
        int bufferSize = 8192;
        byte[] buffer = new byte[bufferSize];
        int read;
        int totalRead = 0;
        int remaining = dis.readInt();
        FileOutputStream fos = new FileOutputStream("video_received.mp4");
        while ((read = dis.read(buffer, 0, Math.min(buffer.length, remaining))) > 0) {
            totalRead += read;
            remaining -= read;
            fos.write(buffer, 0, read);
        }
        fos.close();
        dos.close();
        dis.close();
        socket.close();
    }
}

这个示例基于TCP协议，通过将视频文件读入字节数组中来进行传输。服务端首先读取视频文件并将其发送到客户端，客户端则读取并保存接收到的文件。注意，这里的代码示例并不适用于大型文件，因为它们可能会导致内存问题。
