        #region IP Camera Connect/Disconnect

        private void ConnectIPCamera_Click(object sender, RoutedEventArgs e)
        {
            var host = HostTextBox.Text;
            var user = userTextBox.Text;
            var pass = Password.Password;

            _ipCamera = IPCameraFactory.GetCamera(host, user, pass);
            if (_ipCamera == null) return;
            _connector.Connect(_ipCamera.VideoChannel, _provider);

            _ipCamera.Start();
            _videoViewerWPF.Start();

        }

        private void DiconnectIPCamera_Click(object sender, RoutedEventArgs e)
        {
            _videoViewerWPF.Stop();

            _ipCamera.Disconnect();
            _ipCamera.Dispose();

            _connector.Disconnect(_ipCamera.VideoChannel, _provider);
        }
        #endregion
    }
}

有人可以告诉我该怎么做吗？它告诉我，我无法将_videoViewerWPF.SetImageProvider(_provider)行从Ozeki.Media.BitmapSourceProvider转换为Ozeki.Media.IImageProvider，而且我完全不知道该怎么做才能起作用。

我几次尝试做某事，但我什至不知道我在做什么。
如果有人可以帮助我，我将不胜感激，这样我就可以完成。

在YouTube上观看Ozeki视频C# camera tutorial #3 - Camera viewer之后，我遇到了同样的问题。

自该视频以来，API可能已经继续运行，因为Ozeki网站(How to connect to an RTSP camera and display the picture in C#)上的示例代码使用了DrawingImageProvider而不是BitmapSourceProvider:

...

private DrawingImageProvider _provider = new DrawingImageProvider();

...

...然后(对于WPF应用):

_videoViewerWpf.SetImageProvider(_provider);

就我而言，这解决了编译器错误，现在我可以在WPF应用程序中显示RTSP视频。
