Python pygame.camera”的英文缩写；livefeed“；在tkinter窗口内（在raspbian上）

我已经研究过在tkinter窗口中嵌入pygame窗口（参考：）

我想用它来嵌入pygame.camera模块制作的快照（可能是livefeed）

在评论中说，当评论出

os.environ['SDL\u VIDEODRIVER']='windib'

然而，我无法让嵌入工作正常进行，也无法用pygame制作快照，我也无法找出问题的原因。以下是我编写的代码：

---

在设置

os.environ['SDL\u WINDOWID']之后，必须使用
pygame

os.environ['SDL_WINDOWID'] = str(...)
pygame.init()


编辑：它适用于Linux Mint 18.2

在
Viewer
中，您有方法
refresh（self）
和按钮
self.refresh=button（）
-对于python，这意味着
button
替换了方法。可能一些代码在嵌入框架中无法工作-在获得工作示例之前，开始删除代码行。谢谢！我明天会测试这个。。还感谢您指出
self.refresh
bug。以这种方式运行时，我遇到了一个内核错误（使用带有内置IPython控制台的spyder3 IDE）。摄像头检测工作正常，因为当没有检测到摄像头时，我会遇到异常。编辑：好的，很抱歉，我遗漏了您在
snap（）
方法中更改的另一部分代码。现在它起作用了。非常好的帮助：）我应该在更改代码时在代码中添加注释-但我忘了；）
