我正在尝试在 Ubuntu Desktop 12.04 LTS 上安装rmovie gem 。ffmpeg已安装，但出现此错误：
$ gem install rmovie
Building native extensions. This could take a while...
ERROR: Error installing rmovie:

Could not create Makefile due to some reason, probably lack of
necessary libraries and/or headers. Check the mkmf.log file for more
details. You may need configuration options.

第一次尝试是将 avcodec 重新定位到安装程序正在搜索它的位置。没有成功。下一步 - 更正四重文件中的路径以将其指向 avcodec 所在的位置。没有成功。
这是什么四重物以及如何强制它工作？
或者也许有一些替代 rmovie？
