如何在 CentOS 8 上安装 FFmpeg

开发笔记 admin 2个月前 (05-27) 231次浏览 已收录 0个评论 扫描二维码

CentOS7 安装ffmpeg
自带的yum库不包含ffmpeg软件包,借助第三方YUM源下载ffmpeg
1.升级yum,安装Nux Dextop Yum 源
sudo yum install epel-release -y
sudo yum update -y
sudo rpm --import http://li.nux.ro/download/nux/RPM-GPG-KEY-nux.ro
sudo rpm -Uvh http://li.nux.ro/download/nux/dextop/el7/x86_64/nux-dextop-release-0-5.el7.nux.noarch.rpm
2.安装FFmpeg 和 FFmpeg开发包
sudo yum install ffmpeg ffmpeg-devel -y
3.测试
ffmpeg

现在用的Centos8,那么CentOS8怎么安装ffmpeg?

同样CentOS 8 源仓库中也没有提供。

可以选择通过源文件编译安装 FFmpeg,或者使用dnf工具从Negativo17源仓库中安装。

1.Negativo17软件源依赖EPEL 和 PowerTools 软件源。

sudo dnf install epel-release
sudo yum config-manager --set-enabled PowerTools
sudo yum config-manager --add-repo=https://negativo17.org/repos/epel-multimedia.repo

2.一旦软件源被启用,安装FFmpeg:

sudo dnf install ffmpeg

3.通过检测版本号,验证FFmpeg安装:

ffmpeg -version

FFmpeg已经安装OK。接下来运行

ffmpeg -re -i "001.mp4" -vcodec h264 -acodec aac -f rtp_mpegts rtp://127.0.0.1:10000

如下:
