场景描述

ffmpeg是著名的流媒体工具，CentOS 8 上安装 ffmpeg 却提示如下所示的错误！

解决过程

Q:

I was trying to install erlang package on CentOS8 box from EPEL8. And I got this message -> - nothing provides libSDL2-2.0.so.0()(64bit) needed by wxGTK3-3.0.4-10.el8.1.x86_64

Which I found weird, I rarely see dependencies errors on a vanilla centos box with EPEL. But I couldnt find the SDL2 package.. RHEL 8 does have it.
SDL2, SDL2-devel, SDL2-static

A:

Nevermind! I found them in the powertools c8 repos. http://mirror.leaseweb.com/centos/8/PowerTools/x86_64/os/Packages/

R:

I’ve enable repo:
sudo dnf config-manager –set-enabled PowerTools

List your repos:
sudo dnf repolist all
