在opensuse15.4leap中安装许多解码器让火狐浏览器firefox播放网页视频
实际难题：
在opensuse15.2和15.3leap中安装flash-player、ffmpeg-4、gstreamer-plugins和vlc-codecs就能让火狐浏览器firefox播放酷狗、网易云音乐、优酷、哔哩哔哩网站的视频，但在opensuse15.4却是不能播放视频，提示：“没有找到支持的视频格式和MIME类型”
系统opensuse15.4leap自带火狐浏览器firefox版本是91.8.0esr (64 位)

由 guoyunhe 开发的 opi (Open Build Service Package Installer) 可以在 Leap 和 Tumbleweed 上快速安装解码器。

自动安装50个解码器软件包，就能播放酷狗、网易云音乐、优酷、哔哩哔哩网站的视频，让我很奇怪的地方是它竟会连带安装网易云音乐客户端
