This answer is from Chatgpt 3.5. The information about error:

qt.qpa.plugin: Could not find the Qt platform plugin "xcb" in ""

Answer:

export QT_PLUGIN_PATH=/path/to/Qt/plugins
E.g. export QT_PLUGIN_PATH=/media/sdtv/新加卷/MyCode/MiVOS/venv/lib/python3.7/site-packages/PyQt5/Qt5/plugins

本次文档测试的系统为Ubuntu 16.04，很多通过apt install安装的库都很破旧
想要vlc实现解码稀有编码格式必须能够完整地安装vlc，通过snap或apt安装的vlc没有办法以root用户运行，因此只能重新编译vlc，并在编译前配置时加入允许root用户运行的选项(enable-run-as-root)，当然如果转码程序本身可以在不用root用户运行的情况下就能够正常运行的话直接通过snap install vlc就可以（通过apt安装的vlc十分破旧），不需要再按照这个文档编译vlc
