我正在尝试创建从IP Camera显示视频的程序。

这是我的代码:

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 Emgu.CV;                  //
using Emgu.CV.CvEnum;           // usual Emgu Cv imports
using Emgu.CV.Structure;        //
using Emgu.CV.UI;
using System.IO;
using System.Reflection;
using System.Windows;
using System.Runtime.InteropServices;
using Emgu.Util;
using System.Net;


namespace WindowsFormsApplication1
{
    public partial class Main : Form
    {
        public Main()
        {
            InitializeComponent();
        }

        public Capture _capture;
        public Mat imgOriginal;

        private void imageBox2_Click(object sender, EventArgs e)
        {
        }

        private void label1_Click(object sender, EventArgs e)
        {
        }

        public void button1_Click(object sender, EventArgs e)
        {
            _capture = new Capture("http://192.168.1.148:8080/video");
            _capture.ImageGrabbed += ProcessFrame;
            _capture.Start();
        }

        public void ProcessFrame(object sender, EventArgs arg)
        {
            imgOriginal= _capture.QueryFrame();
            ibOriginal.Image = imgOriginal;
        }
    }
}

它陷入了这一步(没有期待):

imgOriginal= _capture.QueryFrame();

也许我应该调用方法,但我不知道怎么做。 我正在使用Emgu 3.1.0 Link to Doc

我成功解决了这个问题。我犯了一些规范和语法错误。 我为社区提供了工作代码:

            }
            catch (Exception e)
            {
                MessageBox.Show(e.Message);
                return;
            }

            Application.Idle += ProcessFrame;
        }
        void ProcessFrame(object sender, EventArgs e)
        {
            Mat frame = _capture.QueryFrame();

            ibOriginal.Image = frame;
        }
        public void button1_Click(object sender, EventArgs e)
        {



        }


    }
