Question

有人可以给我一个完整的例子，使用这个用 VB.NET 或 C# 编写的库在 picturebox 中显示流的图像

Answer 1

这是一个非常非常简单的表单，它使用了 AForge.Video.MJPEGStream 类。

private MJPEGStream VideoStream = new MJPEGStream();

private void frmMain_Load(object sender, System.EventArgs e)
{
    VideoStream.Source = "URL_HERE";
    VideoStream.Login = "USERNAME_HERE";
    VideoStream.Password = "PASSWORD_HERE";

    VideoStream.Start();
}

private void frmMain_FormClosing(object sender, System.Windows.Forms.FormClosingEventArgs e)
{
    VideoStream.Stop();
}

private void VideoStream_NewFrame(object sender, AForge.Video.NewFrameEventArgs eventArgs)
{
    Bitmap FrameData = new Bitmap(eventArgs.Frame);

    pbStream.Image = FrameData;
}

private void VideoStream_VideoSourceError(object sender, AForge.Video.VideoSourceErrorEventArgs eventArgs)
{
    Debug.WriteLine(eventArgs.Description);
}
public frmMain()
{
    InitializeComponent();
    this.FormClosing += new EventHandler(frmMain_FormClosing);
    this.Load += new EventHandler(frmMain_Load);
    VideoStream.NewFrame += new EventHandler(VideoStream_NewFrame);
    VideoStream.VideoSourceError+= new EventHandler(VideoStream_VideoSourceError);
}
