我想使用我的相机捕获网络摄像头.为此,我使用了2个参考：AForge.Video.dll和AForge.Video.DirectShow.dll.

Here’s我发现一个片段：

public FilterInfoCollection CamsCollection;

public VideoCaptureDevice Cam = null;

void Cam_NewFrame(object sender,NewFrameEventArgs eventArgs)

{

frameholder.Source = (Bitmap)eventArgs.Frame.Clone();

/* ^

* Here it cannot convert implicitly from System.Drawing.Bitmap to

* System.Windows.Media.ImageSource

*/

}

private void startcam_Click(object sender,RoutedEventArgs e)

{

CamsCollection = new FilterInfoCollection(FilterCategory.VideoInputDevice);

Cam = new VideoCaptureDevice(CamsCollection[1].MonikerString);

Cam.NewFrame += new NewFrameEventHandler(Cam_NewFrame);

Cam.Start();

}

private void stopcam_Click(object sender,RoutedEventArgs e)

{

Cam.Stop();

}

}

他们使用PictureBox来显示帧.当我在WPF工作时,我使用了this

总结一下这里我的代码看起来像现在.

public FilterInfoCollection CamsCollection;

public VideoCaptureDevice Cam = null;

void Cam_NewFrame(object sender,NewFrameEventArgs eventArgs)

{

System.Drawing.Image imgforms = (Bitmap)eventArgs.Frame.Clone();

BitmapImage bi = new BitmapImage();

bi.BeginInit ();

MemoryStream ms = new MemoryStream ();

imgforms.Save(ms,ImageFormat.Bmp);

ms.Seek(0,SeekOrigin.Begin);

bi.StreamSource = ms;

frameholder.Source = bi;

/* ^ runtime error here because `bi` is occupied by another thread.

*/

bi.EndInit();

}

private void startcam_Click(object sender,RoutedEventArgs e)

{

CamsCollection = new FilterInfoCollection(FilterCategory.VideoInputDevice);

Cam = new VideoCaptureDevice(CamsCollection[1].MonikerString);

Cam.NewFrame += new NewFrameEventHandler(Cam_NewFrame);

Cam.Start();

}

private void stopcam_Click(object sender,RoutedEventArgs e)

{

Cam.Stop();

}
