OpenCV linux如何安装FFMPEG

Question

有人可以帮助我提供有关如何在 linux 上安装 FFMPEG 的工作方法，我已经遵循了几个教程，它们似乎可以工作，除了在系统中从未找到所有 FFMPEG 之后，即使在几次系统重新启动之后我最后一次尝试来自此链接Compile FFmpeg on Ubuntu, Debian, or Mint

我在教程中做了所有的事情，但是当我运行 man ffmpeg 时它告诉我没有找到手册并且 OpenCV 也没有检测到它，我尝试调用 Core.getBuildInformation() 并且输出是：

Answer 1

如果可以，请使用预先配置了所有内容的 docker Image。让您的生活更轻松 --- Docker Image

Answer 2

在.deb 系统上，您需要安装 *libavformat-dev、libavcodec-dev、libswscale-dev、libavresample-dev 软件包。
