java - 将视频流式传输到服务器

Question

我正在尝试使用 Java 将视频从另一台机器流式传输到服务器，对于初学者来说，我只是尝试使用原始套接字连接和字节流传输文件。然而，事情并没有以同样的方式出现。如果我以这种方式传输文件，我的计算机上的 3MB 文件最终在服务器上会变成 5MB。我正在尝试使用视频文件进行此操作，当我下载它时，生成的文件实际上会“播放”并且长度正确，但没有图像。代码如下:

客户端(流媒体):

public static void main(String[] args){
    Socket sock = null;

    try{
        System.out.println("Connecting...");
        sock = new Socket("server.com", 8080);
        InputStream is = new FileInputStream(new File("Bear.wmv"));
        byte[] bytes = new byte[1024];

        OutputStream stream = sock.getOutputStream();

        int count = is.read(bytes, 0, 1024);
        while (count != -1){
            stream.write(bytes, 0, 1024);
            count = is.read(bytes, 0, 1024);
        }

        is.close();
        stream.close();
        sock.close();

    }catch (Exception e){
        e.printStackTrace();
    }
}

服务器(接收者):

public static void main(String[] args){
    ServerSocket sock = null;
    try {
        sock = new ServerSocket(8080);
    } catch (IOException e) {
        System.out.println("Could not instantiate socket:");
        e.printStackTrace();
        return;
    }

    Socket clientSock = null;
    while(true){

        try{

            System.out.println("Waiting for connection...");
            clientSock = sock.accept();
            final Socket fin = clientSock;
            System.out.println("Connection accepted");
            System.out.println("Spawning thread...");
            Thread trd = new Thread(new Runnable(){
                public void run(){
                    try {
                        try {
                            Thread.sleep(5000);
                        } catch (InterruptedException e) {
                            e.printStackTrace();
                        }

                        System.out.println("Receiving video...");
                        File video = new File("test.wmv");
                        FileOutputStream fos = new FileOutputStream(video);
                        byte[] data = new byte[1024];
                        int count = fin.getInputStream().read(data, 0, 1024);
                        while (count != -1){
                            fos.write(data, 0, 1024);
                            count = fin.getInputStream().read(data, 0, 1024);
                        }
                        fos.close();
                        fin.close();
                        System.out.println("Done receiving");
                    } catch (IOException e) {
                        // TODO Auto-generated catch block
                        e.printStackTrace();
                    }}
            });
            trd.start();

        }catch(IOException e){
            System.out.println("Could not accept");
            e.printStackTrace();
        }


    }



}

有什么想法吗？提前致谢!

所以我找到了问题所在。

我将服务器更改为仅写入“count”个字节

while (count != -1){
       fos.write(data, 0, count);
       count = fin.getInputStream().read(data, 0, 1024);
}

现在可以了:)

谢谢!
