在 Centos8 上观看 Netflix

我在华硕上安装了 Centos 8.5.2111。我试图在 Firefox 91 上观看 Netflix，但存在编解码器和协议。我设置了 Widevine 和 Cisco H264 插件，但它不起作用。谷歌搜索表明我需要 ffmpeg 和 ffmpeg-devel。好的，我运行这些命令，结果如下：

好的，刷新我的 Netflix 标签仍然不起作用。我需要 libSDL2。我能找到的最接近的是SDL，SDL-devel我安装了它，但它无助于安装 ffmpeg。我该怎么办？

答案1

我不是基于 rpm 的发行版的专家，但你试过运行吗 sudo yum install ffmpeg ffmpeg-devel --nobest？根据输出结果判断，这个可能有效。

此外，你可能缺少一些存储库（这只是猜测，因为你没有发布yum repolist）这里有一个我找到的指南，并且根据您提供的输出判断，您没有完全满足要求。我的猜测得到了证实这论坛帖子中，一位 CentOS 用户在使用 SDL2 库时遇到了类似的问题，他只需要启用powertools 仓库事物。

答案2

我跟随关联由@savchenko-dmitriy 提供，在安装前的最后一步ffmpeg说安装 PowerTools 像这样$ sudo dnf config-manager –enable PowerTools

对我来说工作是这样的：-

sudo dnf config-manager --enable   powertools

之后我进行安装并且它工作

$ sudo dnf install ffmpeg
$ sudo dnf install ffmpeg ffmpeg-devel
