我在我的 GoblinXNA 程序中遇到了一个问题，即屏幕分辨率，如果我使用 480*640 一切都很好并且我的应用程序运行良好

captureDevice.InitVideoCapture(0, FrameRate._60Hz, Resolution._640x480,
                ImageFormat.R8G8B8_24, false);

但如果我将其更改为 800x600 或 1280x1024，如下所示：

captureDevice.InitVideoCapture(0, FrameRate._60Hz, Resolution._800x600, ImageFormat.R8G8B8_24, false);

我有一个例外

GoblinXNA.GoblinException was unhandled
  Message=Could not start video stream
Could not setup graph

知道如何解决这个问题吗？

谢谢

我设法通过将 DirectShowCapture.cs 中的分辨率更改为 1280x720 并重新编译 GoblinXNA.dll 来解决问题
