问题描述
我下载了 VLCJ JavaFX 示例，以便确定问题与我的代码无关，但我仍然无法让它在 Ubuntu 上运行，只能在 Windows 10 上运行。我收到了这个奇怪的错误，导致了这个错误"hr_err_pidxxxx.log"
我使用的是 openjdk-15 和 Ubuntu 20.10，安装最少，但我已经安装了完整的 vlc，想 sudo apt install vlc 和 ffmepg（不确定是否需要），以便加载所有必要的本机库。
值得一提的是，我不得不将 vlcj 的 pom.xml 依赖项更改为 4.7.0，因为 5.0.0-SNAPSHOT 在 Maven Repo 上不可用。
