I'm writing C# code which can display logitech usb c525 webcam to picturebox. I tried many sample codes from web with AFORGE/OpenCvSharp/avicap32.dll and no success, keep displays no image on picturebox. Webcam, C525, is working with other application like a camera app in Win10 so webcam is working, not broken.
Could you look at my code what I'm missing?
If I using default webcam on laptop, it's working well with my code
using System;
using System.Collections.Generic;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;
using AForge.Video;
using AForge.Video.DirectShow;
namespace LogitechWebCam
{
public partial class Form1 : Form
{
//Create webcam object
VideoCaptureDevice videoSource;
private FilterInfoCollection VideoCaptureDevices;
private VideoCaptureDevice FinalVideo;
public void AForgeLoadDevice()
{
VideoCaptureDevices = new FilterInfoCollection(FilterCategory.VideoInputDevice);
foreach (FilterInfo VideoCaptureDevice in VideoCaptureDevices)
{
comboBox1.Items.Add(VideoCaptureDevice.Name);
}
comboBox1.SelectedIndex = 0;
}
public void AForgeOpen()
{
FinalVideo = new VideoCaptureDevice(VideoCaptureDevices[comboBox1.SelectedIndex].MonikerString);
FinalVideo.NewFrame += new NewFrameEventHandler(FinalVideo_NewFrame);
FinalVideo.Start();
}
public void AForgeClose()
{
FinalVideo.Stop();
}
void FinalVideo_NewFrame(object sender, NewFrameEventArgs eventArgs)
{
Bitmap video = (Bitmap)eventArgs.Frame.Clone();
pictureBox1.Image = video;
}
}
}
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;
namespace LogitechWebCam
{
public partial class Form1 : Form
{
LogiWebCam webCam;
WebCamera wc;
public Form1()
{
InitializeComponent();
}
// start cam
private void Button1_Click(object sender, EventArgs e)
{
AForgeOpen();
}
// stop cam
private void Button2_Click(object sender, EventArgs e)
{
AForgeClose();
}
// load cam
private void Button3_Click(object sender, EventArgs e)
{
AForgeLoadDevice();
}
}
}
Build is ok and when I run program, I can see memory increasing from diagnostics window and also I can see C525 webcam led on so actually webcam is working but couldn't display image on picturebox screen.
