标签： c aforge 摄像头 it

对于视频编程，网络上的东西不是很好找，摄像头算是比较初级的东东了，我查了很多资料，才算是有一点结果，现在把摄像头采集程序代码与大家分享一下。（vs2008编译通过）

其中，Aforge.net下载地址http://www.aforgenet.com/framework/

下载lib之后，引用就可以了

foreach (FilterInfo device invideoDevices)
{
comboBox1.Items.Add(device.Name);
}
comboBox1.SelectedIndex = 0; //make dafault to firstcam
}
catch(ApplicationException)
{
DeviceExist =false;
comboBox1.Items.Add("No capture device on yoursystem");
}
}

}
}

}

//videoSource.DesiredFrameSize = new Size(353, 290);
//videoSource.DesiredFrameRate =10;
videoSource.Start();

}

}

this.Dispose();
}

}
