完全删除 GStreamer 并重新安装

我整天都在尝试在 Ubuntu Studio 14.04 上安装更新版本的字幕编辑器，但没有成功。

特别是，我需要安装更新版本的 GStreamer。之前安装的版本是 0.10.something。我整天都从很多来源安装 GStreamer。我添加了一个 ppa 并从那里下载了它，我以几种不同的方式从 .tar 存档安装了它，最后我没有解决任何问题。

更重要的是，现在 Totem 不起作用，如果我尝试从终端启动它，我会在 GUI 中收到此消息：

它是意大利语的，上面写着：“无法启动 Totem。缺少一些必要的插件。检查程序是否正确安装”。

单击“确定”后，它会自行关闭，在终端中我读到：

alex@Sargon:~$ totem

** (totem:3702): WARNING **: Element 'playbin' is missing, verify your installation

** (totem:3702): WARNING **: Element 'audioconvert' is missing, verify your installation

** (totem:3702): WARNING **: Element 'scaletempo' is missing, verify your installation

** (totem:3702): WARNING **: Element 'autoaudiosink' is missing, verify your installation

(totem:3702): Gtk-WARNING **: A floating object was finalized. This means that someone
called g_object_unref() on an object that had only a floating
reference; the initial floating reference is not owned by anyone
and must be removed with g_object_ref_sink().

我卸载它并重新安装它，但问题仍然存在。

所以我假设我搞砸了 GStreaming。我想我能做的最好的事情就是完全删除它而不是安装默认版本。

我怎样才能做到这一点？
