  参考大佬 https://bbs.aw-ol.com/topic/362/diy教程-d1的双屏异显第一弹来啦-d1同时支持两个屏幕-一共做ui交互-一边个播放视频?_=1713492912563
  帖子，
  尝试去做实验，
  发现修改 libuapi 库，videoOutPort.c 文件 SCREEN_0 为1 ，
  通过 tplayerdemo播放视频，HDMI无任何输出，
  但是通过 colorbar 调试，两边是可以显示不同的画面。
  如果不修改 videoOutPort.c 文件 SCREEN_0 为1 ，则MIPI DSI可以正常播放视频。

  目前认为是是 硬件部分 没问题，两个图层已经创建，单独 MIPI DSI 运行LVGL示例没问题，但是Tplayerdemo在调取disp图层 播放视频时无法从 hdmi 输出，有没有比较了解的大佬指点一二？
