这段代码是一个函数，它的功能是让用户选择一个 RTSP 地址，然后加载这个地址的视频流。具体来说，它会先创建一个窗口对象，并将窗口显示出来。然后，它会读取一个配置文件，如果这个配置文件不存在，它会将一个默认的 RTSP 地址写入配置文件中。接着，它会从配置文件中读取 RTSP 地址，并将这个地址显示在窗口中的文本框中。最后，它会连接一个点击事件，当用户点击“确认”按钮时，会调用 `load_rtsp` 函数来加载用户选择的 RTSP 地址的视频流。

根据提示，可能是因为在不同的线程中尝试停止定时器。你可以尝试在调用 `start()` 方法时，将 `QTimer` 对象传递给 `ImageThread` 类，并在 `ImageThread` 中使用该定时器对象，而不是在 `MyWindow` 类中创建定时器对象。这样可以确保定时器在同一线程中启动和停止，避免出现跨线程问题。

另外，你在 `MyWindow` 类中定义了 `saved_color_photos` 和 `saved_depth_photos` 这两个属性，但是没有看到它们被使用。如果你想使用这两个属性，可以在 `update_saved_color_photos_label` 和 `update_saved_depth_photos_label` 方法中更新它们的值，并在需要时获取它们的值。例如：

def update_saved_color_photos_label(self, num_photos):
    self.saved_color_photos += num_photos
    self.ui.label_5.setText(f"已保存 {self.saved_color_photos} 张")

def update_saved_depth_photos_label(self, num_photos):
    self.saved_depth_photos += num_photos
    self.ui.label_6.setText(f"已保存 {self.saved_depth_photos} 张")

这样在每次保存颜色或深度图像时，`saved_color_photos` 和 `saved_depth_photos` 的值都会相应地增加，并在界面上显示出来。
