Question

我正在使用Visual Studio 2013创建Windows应用程序表单以从我的IP摄像机获取图像，但是不幸的是，一旦单击该按钮，该图像就不会出现在图片框上。我该怎么做才能解决这个问题？

我尝试了各种参考，包括Emgu.Cv，AForge.net等，但这些参考都没有。

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;
using System.Web;
using System.Net;
using System.IO;
using Emgu.CV;

namespace WindowsFormsApp3
{
    public partial class Form2 : Form
    {

        public Form2()

        {
            InitializeComponent();
        }

        private void button1_Click(object sender, EventArgs e)
        {
            getFrame();
        }

        private void getFrame()
        {
            string sourceURL = "http://admin:testground@192.xxx.x.x/video/mjpg.cgi";

            byte[] buffer = new byte[1280 * 800];
            int read, total = 0;

            HttpWebRequest req = (HttpWebRequest) WebRequest.Create(sourceURL);
            WebResponse resp = req.GetResponse();

            Stream stream = resp.GetResponseStream();

            while((read = stream.Read(buffer, total, 1000)) != 0)
            {
                total += read;
            }

            Bitmap bmp = (Bitmap)Bitmap.FromStream(new MemoryStream(buffer, 0, total));

            pictureBox1.Image = bmp;
        }
    }
}

预期结果应该显示我的IP摄像机的视频，但实际输出是

An unhandled exception of type 'System.Net.WebException' occurred in System.dll

Additional information: The remote server returned an error: (401) Unauthorized.

如何使用Visual Studio 2013从IP摄像机捕获图像？
