我在两台台式电脑和一台笔记本电脑中使用 Ubuntu-Studio 20.04.3 LTS。
那台笔记本电脑是 HP 250 G5 设备，我们可以将其视为旧电脑。
该笔记本电脑的内部视频适配器无法播放每秒超过 30 帧的超高清视频。
我使用相同的视频、相同的分辨率、相同的文件格式，但分别以 29.97 fps 和 50 fps 进行测试。29.97 fps 版本播放效果“令人满意”。我的意思是，我们可以看到它（有些卡顿，但不是太难看）。50 fps 版本... 不予置评。简而言之：太糟糕了！
当然，正确的解决方案是购买一台新设备。
但是...我想知道在旧设备中是否有办法解决这个问题。
有什么想法吗？？？
