GoblinXNA:更改屏幕分辨率时异常

本文关键字：分辨率 异常 屏幕 GoblinXNA | 更新日期: 2023-09-27 18:36:26

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

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

但是，如果我像这样将其更改为 800x600 或 1280x1024：

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

我收到异常

知道如何解决这个问题吗？

谢谢

GoblinXNA:更改屏幕分辨率时异常

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

.dll
