MPlayer

Name: MPlayer
Availability: InStock
Author: The MPlayer Project

MPlayer is an open source media player that runs entirely from the command line and plays virtually any audio or video format without requiring external codec packs. It ships with its own decoders built on FFmpeg and supports local files, network streams, DVDs, and subtitle overlays, all controlled through terminal commands and keyboard shortcuts.

What it does

Type mplayer file.mp4 and playback starts in a new window. Press space to pause, q to quit, arrow keys to seek. MPlayer decodes hundreds of formats internally, including H.264, HEVC, AVI, MKV, FLAC, Ogg Vorbis, and legacy codecs that modern players sometimes drop. It handles network streams just as easily: pass an HTTP, RTSP, or MMS URL as the argument and MPlayer buffers and plays it live. For DVD playback, mplayer dvd://1 launches the first title from a disc.

Subtitles load with the -sub flag followed by the SRT or SSA file path. Video filters apply through -vf: brightness and contrast adjustments, rotation, cropping, deinterlacing. The -speed flag changes playback rate from 0.1x to 100x, which is practical for transcribing audio or skimming through long recordings. MPlayer can also extract audio from video files to WAV using -ao pcm:file=output.wav -novideo, functioning as a lightweight extraction tool.

Advantages

Plays almost every audio and video format without installing additional codecs
Lightweight and scriptable, ideal for automation and server environments
Runs on Windows, Linux, macOS, and BSD with the same command syntax
No graphical interface overhead means it starts and responds instantly

Drawbacks

No graphical interface at all, requiring all interaction through terminal commands
Development has largely shifted to the mpv fork, which receives more frequent updates
Configuration requires editing a text file (mplayer.conf) rather than using a settings menu
No playlist management, media library, or built-in file browser

Who it is for

I keep MPlayer installed on headless Linux machines where I need to test audio output or extract tracks from video files through SSH. It plays things that other players refuse to open, and it does so without pulling in large GUI frameworks or codec dependencies. If you work in the terminal regularly, enjoy scripting media tasks, or maintain servers, MPlayer fits naturally into that workflow. For anyone who expects a visual interface with playlists and library management, mpv or VLC will be a better starting point.

Frequently Asked Questions

Is MPlayer free?

Yes. MPlayer is free and open source, licensed under the GPL. It runs on Windows, Linux, macOS, and BSD at no cost.

Does MPlayer have a graphical interface?

MPlayer itself runs from the command line. Graphical frontends like SMPlayer and GNOME MPlayer provide a window-based interface that controls MPlayer underneath.

What is the difference between MPlayer and mpv?

mpv is a fork of MPlayer with a modernized codebase, better default settings, and active development. MPlayer's original project receives fewer updates. Most users today choose mpv or SMPlayer instead.

Can MPlayer play network streams?

Yes. MPlayer supports HTTP, RTSP, MMS, and other streaming protocols. Pass the URL as an argument on the command line and it connects and plays directly.
