Required Redistributables

Before you begin, ensure you have the following packages installed:

• Video capture redist x86 x64
• LAV redist x86 x64

Implementation Example

Below is a complete WinForms example showing how to integrate IP camera preview functionality:

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 VisioForge.Core.VideoCapture;
using VisioForge.Core.Types;
using VisioForge.Core.Types.Output;
using VisioForge.Core.Types.VideoCapture;

namespace ip_camera_preview
{
    public partial class Form1 : Form
    {
        private VideoCaptureCore videoCapture1;

        public Form1()
        {
            InitializeComponent();
        }

        private void Form1_Load(object sender, EventArgs e)
        {
            videoCapture1 = new VideoCaptureCore(VideoView1 as IVideoView);
        }

        private async void btStart_Click(object sender, EventArgs e)
        {
            // Several engines are available. We'll use LAV as the most compatible. For low latency RTSP playback, use the RTSP Low Latency engine.
            videoCapture1.IP_Camera_Source = new IPCameraSourceSettings()
            {
                URL = new Uri("http://192.168.233.129:8000/camera/mjpeg"),
                Type = IPSourceEngine.Auto_LAV
            };

            videoCapture1.Audio_PlayAudio = videoCapture1.Audio_RecordAudio = false;
            videoCapture1.Mode = VideoCaptureMode.IPPreview;

            await videoCapture1.StartAsync();
        }

        private async void btStop_Click(object sender, EventArgs e)
        {
            await videoCapture1.StopAsync();
        }
    }
}

Key Implementation Details

Setting the IP Camera Source

The code demonstrates configuring the IP camera source with the appropriate URL and engine type:

videoCapture1.IP_Camera_Source = new IPCameraSourceSettings()
{
    URL = new Uri("http://192.168.233.129:8000/camera/mjpeg"),
    Type = IPSourceEngine.Auto_LAV
};

Handling Audio Settings

For simple preview applications, you may want to disable audio playback and recording:

videoCapture1.Audio_PlayAudio = videoCapture1.Audio_RecordAudio = false;

Setting the Capture Mode

The correct mode for IP camera preview is:

videoCapture1.Mode = VideoCaptureMode.IPPreview;

Advanced Options

For production applications, consider implementing:

• Error handling and connection retry logic
• UI feedback during connection attempts
• Camera authentication handling
• Frame rate and resolution control
