C# GoblinXNA:更改屏幕分辨率时发生异常

我在GoblinXNA程序中遇到了一个问题，那就是屏幕分辨率，如果我使用480*640，一切都很好，我的应用程序工作正常

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);

我有个例外

GoblinXNA.GoblinException was unhandled
  Message=Could not start video stream
Could not setup graph
Error HRESULT E_FAIL has been returned from a call to a COM component.

你知道怎么解决这个问题吗

谢谢

我通过将DirectShowCapture.cs中的分辨率更改为1280x720并重新编译GoblinXNA.dll成功地解决了这个问题
