Check If MPlayer Is Installed on Your Server

Note: Installing software needs root access, which is full control of the server. It is for VPS and dedicated server owners.

What is MPlayer?

MPlayer is a free program that plays and reads video and audio files. On a web server, it is not for watching videos. Some websites use it to work with video files. For example, a video-sharing script may call it to read details about an uploaded video.

SSH is a way to type commands on your server from your own computer. You use it for all checks below.

Method 1: Ask where it is

Connect to your server with SSH.
Run this command.

which mplayer

If MPlayer is installed, it prints the file path, such as /usr/bin/mplayer. If nothing prints, it is not installed or not in the search path.

Method 2: Ask for the version

mplayer -v

This starts MPlayer and prints its version. If you see "command not found", it is missing.

Method 3: Ask the package manager

A package manager is the tool that installs and tracks software on Linux.

On CentOS, AlmaLinux or Rocky Linux:

rpm -qa | grep -i mplayer

This lists installed packages that have "mplayer" in the name.

On Ubuntu or Debian:

dpkg -l | grep -i mplayer

This does the same on Debian-style systems.

Install it if missing

On Ubuntu or Debian:

apt-get update
apt-get install mplayer

On CentOS-type systems, MPlayer is not in the standard list. You often have to enable an extra software source first. Ask Hostvento support if you need advice on a safe source.

Warning: Add outside software sources only if you trust them. Take a backup or snapshot of your server first.

Tip: Many scripts also need FFmpeg, another video tool. Check for it with which ffmpeg. If you are not sure, open a support ticket.
