dnf install mplayer

dnf install smplayer

提示仓库

里没有这个软件

fedora默认不提供一些有版权争议的软件，非开源的项目包，所以需要用rpm fusion源，来补充Linux的“软件库”

解决方案:

fedora 26

4.11.11-300.fc26.x86_64

一，添加RPM Fusion源

进入 https://rpmfusion.org/Configuration

点击下载RPM Fusion free for Fedora 26， RPM Fusion nonfree for Fedora 26# cd  /home/for/Downloads/
# yum localinstall rpmfusion-free-release-26.noarch.rpm

# yum localinstall rpmfusion-nonfree-release-26.noarch.rpm

二，安装mplayer, smplayer(如果下载失败，再次执行#dnf install bar)

# dnf install mplayer

#dnf install smplayer
