我想知道是否可以在视频顶部显示图像，让我解释一下：我目前正在进行一个小型万圣节项目，该项目由一个显示视频的数字板组成（https://atmosfx.com/products /unliving-肖像）。因此，我将视频置于暂停状态，当事件发生时，我启动视频并触发跳跃恐慌。我正在使用 OMXPlayer 来管理视频。
当一个人走过棋盘时，角色应该能够用眼睛跟随这个人，我用 Tkinter 和 PIL 做到了这一点（逐帧取决于位置），到目前为止它工作正常但分开，我目前正在尝试将我的两个代码合二为一，但问题仍然存在，我无法更正它，跟随此人的图像不在视频上方而是在下方，我不知道如何解决此问题。我希望这些图像在暂停时位于视频顶部，并在视频开始后消失。
