视频编辑软件pitivi基本功之安装篇
台式机的系统是openSUSE-Leap-15.5-DVD-x86_64
应用程序——工具——终端，切换到root用户

缺少的可选依赖：

• cvtracker GStreamer element not found on the system
  -> enables object tracking
  缺少的可选依赖：
• librosa 没有在该系统上发现
  -> 启用节拍检测功能

正常安装pitivi后运行报错缺少cvtracker和librosa，尝试过都不能成功安装cvtracker，根据官网提示可以通过flatpak来安装pitivi

先卸载之前安装过的pitivi
localhost:~ # zypper remove pitivi
localhost:~ # zypper install flatpak
localhost:~ # flatpak remote-add --if-not-exists flathub https://dl.flathub.org/repo/flathub.flatpakrepo
localhost:~ # flatpak remote-modify flathub --url=https://mirror.sjtu.edu.cn/flathub
参考上海交通大学软件源镜像服务https://mirrors.sjtug.sjtu.edu.cn/docs/flathub
使用flathub.org网站下载是非常缓慢的，改成使用mirror.sjtu.edu.cn/flathub就非常快速了，大约耗时15分钟左右

localhost:~ # flatpak install flathub org.pitivi.Pitivi

必须要以普通用户ruhong启动pitivi

报错缺少libpython3.10.so，补安装python3-devel就可以了
