OpenCV linux如何安装FFMPEG

问题描述：

有人可以请帮我一个关于如何在Linux上安装FFMPEG的工作方法，我遵循了几个教程，他们似乎工作，除非在系统中找不到任何FFMPEG，即使在几个系统重新启动我的最后一次尝试是从这个链接Compile FFmpeg on Ubuntu, Debian, or Mint OpenCV linux如何安装FFMPEG

我做教程的一切，但是当我运行man ffmpeg它告诉我，没有手动发现OpenCV也没有检测到它，我打过电话了Core.getBuildInformation()输出功率为：

在.deb系统，您需要安装*了libavformat-dev的是，libavcodec-dev的，libswscale-dev的，libavresample-dev的软件包。

它仍然不能检测'FFMPEG' –

你能尝试删除build文件夹并重新运行cmake的？这些可能有ffmpeg版本，比如libavformat-ffmpeg-dev等，你可能也想安装它们。 –

好吧，让我再试一次 –

使用泊坞窗图片里面什么都有，如果你能预先配置。让你的生活变得更轻松--- Docker Image
