Question

我在我的GoblinXNA程序中面临一个问题，即屏幕分辨率，如果我使用480 * 640一切都很好，我的应用程序运行正常

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

但如果我将其更改为800x600或1280x1024，请执行以下操作：

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

我得到例外

GoblinXNA.GoblinException was unhandled

任何想法如何解决这个问题？

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
