问题描述
我想知道是否可以在视频上显示图像，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 (https://atmosfx.com/products/unliving-portraits) 的数字板组成。所以我把我的视频放在暂停状态，当一个事件发生时，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，角色应该能够用他们的眼睛跟随这个人，我用 Tkinter 和 PIL（逐帧取决于位置）做到了这一点，到目前为止它工作正常，但分开，我是目前正在尝试将我的两个代码合二为一，但问题仍然存在，我无法纠正它，此人后面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。 我希望这些图像在处于暂停状态时显示在视频的顶部，并在视频开始后消失。
