wxPython：视频未显示，但我可以听到音频

Question

我正在尝试制作一个简单的程序来保留或删除文件夹（及其子文件夹）中的视频，但是虽然我可以听到视频，但看不到它。

您已经将按钮放在视频顶部，没有指定其大小或位置，所以这就是您所看到的。

最好使用一些尺寸调整器来避免此类事情，因为他们会为您整理位置和布局。

真的！大致尝试这样的事情。 （您可能不需要指定

backend

，否则它对于您的系统来说是错误的。）

        self.panel = wx.Panel(self)
        self.media_ctrl = wx.media.MediaCtrl(self, szBackend=wx.media.MEDIABACKEND_GSTREAMER)

        self.yes_button = wx.Button(self.panel, label="Yes (Keep)")
        self.no_button = wx.Button(self.panel, label="No (Delete)")

        sizer = wx.BoxSizer(wx.VERTICAL)
        sizer2 = wx.BoxSizer(wx.HORIZONTAL)
        sizer.Add(self.media_ctrl, 1, wx.EXPAND|wx.ALL, 5)
        sizer2.Add(self.yes_button)
        sizer2.Add(self.no_button)
        self.panel.SetSizer(sizer2)
