History
XMMS was originally written as x11amp by Peter and Mikael Alm in November 1997.[1] The player was made to resemble Winamp, which was first released in May that year. x11amp received Winamp skin support in version 0.7 on May 6, 1998.[2] Though the original release was made under a license that did not provide any access to the program's source code, it is now released under the GPL-2.0-or-later.
On June 10, 1999, 4Front Technologies decided to sponsor x11amp development and the project was renamed to XMMS[3] - the name being an acronym for X MultiMedia System. Most XMMS users take this to mean "X11 MultiMedia System" or "X Window System MultiMedia System"; the official interpretation of the "X" is "Cross-platform".[4]
In 2002, Peter Alm initiated the XMMS2 project, aiming to produce a successor to XMMS using all new code and devoted solely to audio playback.[5]
The final version of the player was released in November 2007. After it its development and support were ceased. Modern Linux distributions no longer offer it.
Forks
XMMS continued to use GTK+ 1.x toolkit, despite newer versions of the toolkit being released. The primary reason for this reluctance to upgrade was that many XMMS plugins (written by third parties) were dependent on the older version of GTK+ to properly function, e.g., "about" boxes and configuration dialogs. Many software developers considered the XMMS codebase to be poorly designed and difficult to maintain.[citation needed] This led to forks and related projects:
- The Beep Media Player, a fork of XMMS code that uses GTK+ 2, started around 2003
- A GTK+2 based fork by Mohammed Sameer, named XMMS2. It is unrelated to the current XMMS2 project, which uses a new codebase and client/server architecture not derived from XMMS.[7]
- In 2026 Christian Schaller from Red Hat, part of his experiments with AI, revived the project and rewritten it for GTK4/PipeWire.[8][9] It was named XMMS Resuscitated.
