如何在 Ubuntu 14.04（32 位）上安装 ffmpeg？

当我尝试时：

sudo apt-get install ffmpeg

我得到：

Reading package lists... Done
Building dependency tree       
Reading state information... Done
Package ffmpeg is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source

E: Package 'ffmpeg' has no installation candidate

而且我不知道如何安装 ppa 包。
