我正在制作一张将在屏幕上显示的“海报”。海报的核心内容是连续播放的视频。
我正在使用baposter文档类来创建海报（http://www.brian-amberg.de/uni/poster/) 以及media9处理视频的包。
另外，我没有遇到依赖任何一个包的文档的问题，但是当我在文档中media9使用时，视频不会按预期在占位符图像上播放，而是显示在下方并偏移。列出了相同的问题\includevideo{}baposter这里，但作者baposter.cls并没有回答是什么原因导致了这个问题。
是什么原因导致了这个显示问题？看来文件中存在兼容性问题baposter.cls，但我无法查明并修复该问题。
下面是使用 Okular pdf 查看器在 Linux 操作系统上重现该问题的最小示例：
