SMPlayer is built with Qt and is based on MPlayer. This makes it quite portable, since MPlayer and Qt are already available on all major operating systems. On the operating systems on which SMPlayer has not yet been ported to, it is likely possible to run the application through binary compatibility with another Unix or Linux.

In addition to the Windows packages, official binary packages are provided for Ubuntu. Many distributions provide packages in their repositories.

For FreeBSD, SMPlayer is available for installation from source via the ports tree and also available as binary packages for most major FreeBSD releases.

OpenBSD also provides binary packages and is available in its ports collection as well.

SMPlayer is not available yet on NetBSD or DragonFly BSD, either in binary format or in pkgsrc. NetBSD should be able to run the FreeBSD binary without much trouble.

Windows

[edit]

Current versions of SMPlayer bundle all codecs inside the installer, therefore there is no longer any need for a web connection during install. Originally, SMPlayer was distributed with a NSIS generated setup (previously Inno Setup) Since version 0.6.7. This installer was capable of downloading and installing the latest MPlayer and MPlayer codec packages during setup. An alternative installer was available with MPlayer included for off-line installs.[9]

"Portable" (no installer) versions are also available in PortableApps format.[10] An independent Doom9 developer offers different Windows packages based on MPlayer binaries ported by Gianluigi Tiesi.[11][12]

Abandoned forks

[edit]
  • UMPlayer: An abandoned fork that offered integration with SHOUTcast streams and support for Mac OS X.[13][14][15] Since the UMPlayer project is no longer active, the SMPlayer team recommend to use SMPlayer instead, however, they do provide their own updated version of UMPlayer with fixes for its YouTube support[16]
  • SMPlayer2: An abandoned fork targeted at mplayer2 users, as of 2014 replaced by SMPlayer with mpv.[6][17]

History and Development

Origins and Initial Release

SMPlayer was developed by Ricardo Villalba, a Spanish , as a cross-platform (GUI) for the command-line media player . Villalba initiated the project to create an accessible frontend that would make MPlayer's powerful playback capabilities available to users without requiring familiarity with terminal commands. The core motivation behind SMPlayer's creation stemmed from MPlayer's limitations as a text-based tool, which, despite its robustness in handling diverse audio and video formats, lacked an intuitive native GUI and made tasks like subtitle management cumbersome for non-technical users. By leveraging the Qt framework, Villalba designed SMPlayer to support both and Windows from the outset, aiming to streamline media playback while preserving MPlayer's backend efficiency. SMPlayer's initial release took place on December 11, 2006, marking the debut of version 0.6.x and introducing basic features such as simplified video loading, playback controls, and preliminary subtitle support. This launch addressed the growing need for a free, open-source media player that bridged the gap between MPlayer's technical prowess and everyday usability on desktop environments.

A significant milestone came in 2008 with the addition of support in version 0.6.0, allowing users to automatically skip specific segments in videos by placing an .edl file with the same name as the media file. This feature enhanced viewing experiences for edited content, such as skipping commercials or intros, and integrated directly with MPlayer's capabilities. Concurrently, version 0.7.0 introduced initial support, enabling direct playback of videos via input, marking SMPlayer's entry into handling. In 2014, version 14.9.0 represented a pivotal technical shift by adding support for the mpv backend as an alternative to , offering improved performance and modern features like better . This update allowed users to select mpv in preferences, facilitating a smoother transition for those seeking enhanced video rendering and subtitle handling. By , further refinements in version 15.9 strengthened mpv integration, including bundled mpv binaries in Windows installers for easier setup. Chromecast integration arrived experimentally in version 17.1 in January 2017, permitting users to stream local files and videos to devices via a web interface, requiring and the webfs package. This expansion broadened SMPlayer's utility for multi-device playback environments. In 2018, version 18.10 advanced capabilities by supporting resolutions up to 4K, with subsequent version 19.1 in 2019 enabling 60fps playback for high-quality streaming. SMPlayer has maintained a pattern of stable, incremental releases, with regular updates addressing compatibility and usability. The latest version, 25.6.0 released on June 8, 2025, focused on bug fixes such as play/pause functionality, screensaver inhibition on , and disc playback stability, alongside general improvements to ensure ongoing reliability.

Community involvement is evident through ongoing issue tracking and discussions on , where users report and resolve bugs related to cross-platform performance, such as audio/video synchronization and subtitle handling. Development priorities center on sustaining compatibility with evolving dependencies like mpv—following an earlier transition from —while prioritizing bug fixes and minor enhancements to ensure long-term stability without introducing sweeping new features.

Features

Core Playback Functionality

SMPlayer primarily utilizes as its backend engine for media decoding, enabling the playback of virtually all audio and video formats without requiring external codecs. Additionally, it supports mpv as an alternative backend, providing enhanced performance and compatibility for modern . The player offers robust playback controls, including the ability to remember the exact position within files or chapters upon resumption, allowing seamless continuation from previous sessions. Variable speed playback is supported, which facilitates accelerated viewing or slowed analysis without altering pitch. Audio and video equalizers are integrated, enabling users to adjust frequency responses and visual properties like contrast and brightness during playback. Filters such as (e.g., Yadif algorithm) are available to improve video quality for interlaced sources, alongside other audio and video processing options. SMPlayer provides built-in support for common container formats including , MKV, and MP4, as well as audio formats like . It handles streaming protocols such as HTTP and RTSP natively through its backend engines, supporting live and on-demand media delivery. Subtitle integration is handled during playback for synchronized text display.

Subtitle and Multimedia Support

SMPlayer provides robust subtitle handling, enabling users to automatically search and download subtitles from OpenSubtitles.org directly within the player. To access this feature, users open a video file and navigate to the Subtitles menu, where they select "Find subtitles on opensubtitles.org"; a list of available subtitles in various languages appears, allowing selection and immediate download for seamless integration. Customization options for subtitles include adjustments to font type, size, color, and position, particularly when using SSA/ASS subtitle formats, which can be enabled in the Subtitles menu for enhanced styling control. The player supports multi-language by prioritizing frequently used languages in search results and allowing users to select from multiple tracks embedded in the media or downloaded files. For audio enhancements, SMPlayer allows selection of multiple audio tracks from media files via the Audio menu, facilitating switches between languages or formats during playback. It includes a built-in audio with presets tailored for different music genres, such as rock or classical, which users can apply or customize to adjust bands. Additionally, normalization is available as a filter option in the Audio menu, helping to balance and prevent clipping by automatically adjusting audio levels. SMPlayer integrates online multimedia capabilities, supporting video playback up to and 60fps when configured with the mpv engine and youtube-dl or yt-dlp tool via the Network preferences (as of version 25.6.0). Users can browse and play stations through the dedicated Radio menu, which lists streams for direct access, while TV support is available on systems for compatible capture devices. integration enables casting of local or online media to compatible devices by selecting "Play on Chromecast" from the Play menu, which launches a web-based control interface.

User Interface and Customization

SMPlayer employs a (GUI) built using Qt widgets, ensuring cross-platform consistency across Windows, , and other supported systems. This framework provides a familiar desktop experience with standard controls such as buttons, menus, sliders, and dialogs, all integrated with the underlying or MPV playback engine. The interface emphasizes ease of use, featuring a main video , a control bar for playback navigation, and contextual menus for quick access to options like and audio tracks. The player supports extensive customization through its skinnable interface, allowing users to alter the visual appearance via themes and skins. In the Preferences dialog under the Interface tab, users can select the "Skinnable GUI" option and choose from bundled skins or install additional ones, such as the H2O or themes, which modify colors, icons, and layout elements like the and panel. Icon themes can also be swapped independently to match system aesthetics, with distributions often providing the smplayer-skins package for expanded options. Furthermore, the manager is fully customizable; users can add files or directories via drag-and-drop or the "+" button in the dedicated sidebar, rearrange items, save/load playlists as files, and enable automatic addition of opened media to the queue. Key interaction elements are configurable through the Preferences > Keyboard and Mouse section, where hotkeys can be remapped for actions like play/pause, seek, volume adjustment, and subtitle toggling—default shortcuts include spacebar for pause and arrow keys for seeking. Global multimedia keys (e.g., for next/previous track) can be enabled as system-wide shortcuts, provided they do not conflict with other applications. The on-screen display (OSD) is also user-tunable via the View > OSD menu, offering modes such as "Subtitles only," "Volume + Seek," or full display, with the 'o' key cycling through options to show/hide elements like timecodes, progress bars, and volume indicators during playback. For accessibility, SMPlayer supports over 30 languages, including Spanish, German, French, Italian, Russian, Chinese, and Japanese, selectable in Preferences > General to accommodate diverse users. Additionally, it provides automatic support for (EDL) files, which enable custom edit lists to skip or mute unwanted segments like commercials or intros; users place an .edl file with the same name as the video in the same directory, and SMPlayer loads it seamlessly to apply the cuts during playback.

Platforms and Distribution

Linux and Unix-like Systems

SMPlayer is widely available in the official repositories of major distributions and BSD variants, facilitating easy integration into environments. On , users can access the latest versions through the dedicated Personal Package Archive (PPA) maintained by the developers, which provides up-to-date builds beyond the standard repositories. For , the application is included in the main package repository, ensuring seamless installation on stable releases. distributes SMPlayer via the RPM Fusion free repository, which hosts software not included in the base packages due to licensing considerations. In the BSD ecosystem, offers SMPlayer through its ports collection under the multimedia category, allowing compilation or binary installation tailored to the system's architecture. similarly provides it via ports in the x11 category, emphasizing security-focused builds for its environment. Installation on Linux typically leverages distribution-specific package managers for simplicity and dependency resolution. For Debian-based systems like and , the APT tool is used; after adding the PPA for if needed, the command sudo apt update && sudo apt install smplayer retrieves and installs the package along with essential components such as themes and skins. On , after enabling the RPM Fusion repositories with sudo dnf install https://mirrors.rpmfusion.org/free/fedora/rpmfusion-free-release-$(rpm -E %fedora).noarch.rpm (and the nonfree equivalent if required), users run sudo dnf install smplayer to deploy it via DNF, Fedora's successor to YUM. For BSD systems, users employ pkg install smplayer for pre-built packages or cd /usr/ports/[multimedia](/page/Multimedia)/smplayer && make install clean for port-based builds, while follows a similar ports with pkg_add smplayer or manual compilation. For users preferring custom builds, source compilation is supported on and systems by downloading the tarball or cloning the repository. The process requires installing development dependencies such as Qt5 or Qt6 libraries (e.g., libqt5-dev on Debian-based systems or qt5-qtbase-devel on ), along with build tools like qmake and make; or mpv must also be present for playback functionality, though they are not compiled into SMPlayer itself. Compilation proceeds with qmake to generate Makefiles, followed by make and optionally make install to deploy the binary, typically to /usr/local unless a custom prefix is specified. This method allows adaptations for specific environments but demands familiarity with the system's build . SMPlayer includes Unix-specific adaptations to ensure compatibility with display servers and backends prevalent in and BSD. It natively supports X11, the traditional , for rendering its Qt-based graphical interface and video output. Experimental integration with Wayland is available, enabling direct compositing without X11 intermediaries, though users may encounter playback issues resolvable by environment variables like QT_QPA_PLATFORM=xcb or unsetting WAYLAND_DISPLAY for fallback to XWayland. Core dependencies encompass Qt5 or Qt6 for the user interface framework, providing cross-desktop consistency, and the mpv library (or legacy ) as the engine, which handles decoding and rendering while leveraging codecs for broad format support. These elements allow SMPlayer to function efficiently in resource-constrained setups, such as servers or lightweight desktops.

Windows Packages

SMPlayer provides comprehensive support for Windows operating systems, ensuring compatibility across modern installations. As of version 25.6.0, the official distribution includes a 64-bit installer targeting and later versions. Earlier versions provided 32-bit support for and other legacy systems. These installers are available directly from the project's official website as well as , allowing users to download and set up the application with minimal configuration. A key feature of the Windows packages is the inclusion of essential bundled components to eliminate the need for external dependencies. The installers incorporate executables for both and mpv as multimedia engines, along with built-in that enable playback of virtually all video and audio formats without requiring additional software like K-Lite or external codec packs. This self-contained approach simplifies deployment, particularly for users on restricted systems or those preferring a streamlined installation process. During setup, users can select their preferred (MPlayer or mpv) and optional features such as icon themes and language packs, further customizing the package to their needs. In addition to traditional installers, SMPlayer offers a portable version optimized for Windows, which can be run directly from USB drives or other without any installation required. This edition is distributed through , providing a launcher-wrapped package that maintains all functionality while preserving user settings across devices. Available in a 64-bit variant, the portable release mirrors the bundled elements of the standard installer. Earlier versions offered 32-bit support.

macOS and Portable Versions

SMPlayer provides official support for macOS, introduced in version 21.8.0, with downloadable DMG packages available from the project's releases. The latest version, 25.6.0, targets macOS 10.15 (Catalina) and later, with earlier versions providing compatibility down to macOS 10.14 (Mojave). As the application is not digitally signed, macOS security features may display warnings; users can proceed by right-clicking the app and selecting "Open," or install it via Homebrew with the command brew install --cask --no-quarantine smplayer. Built on the Qt framework, SMPlayer delivers consistent functionality across macOS versions, aligning with its cross-platform design. Portable versions of SMPlayer emphasize standalone deployment without requiring system installation or registry modifications, facilitating use on multiple machines via external storage. For Windows, official portable builds are distributed as 7z archives for 64-bit architectures; extraction allows direct execution of smplayer.exe from any directory, with user configurations saved locally in a "config" subfolder since version 24.5. This edition is also packaged for the PortableApps.com platform, enabling seamless integration with portable application launchers. On Linux and Unix-like systems, portability is supported through the AppImage format, added in version 21.8.0, as well as Snap and Flatpak packages, which bundle all dependencies into a single executable file runnable on most distributions after setting execute permissions—no installation or root access needed. For macOS, the DMG package yields a self-contained application bundle that operates independently once extracted, allowing placement and execution from removable media while maintaining full feature parity with installed versions. These options leverage Qt's cross-platform capabilities to ensure uniform behavior across supported operating systems.

Notable Forks

One notable fork of SMPlayer is UMPlayer, initiated in 2010 by developer Ori Rejwan based on SMPlayer version 0.6.9. This project introduced enhancements such as integrated YouTube video playback and SHOUTcast radio streaming support, allowing users to access online audio and video content directly within the player. Additionally, UMPlayer provided native builds for macOS, improving compatibility on Apple systems compared to the original SMPlayer's reliance on cross-platform Qt widgets. However, development ceased around December 2011 with the release of version 0.98.2, leaving features like YouTube playback non-functional due to upstream changes in video services. Another significant fork, SMPlayer2, emerged in early 2012 as a temporary adaptation of SMPlayer specifically for users of the mplayer2 backend, a fork of the original with improved scripting and performance features. It experimented with alternative backend integrations to address limitations in (IPC) mechanisms, aiming to enhance compatibility with mplayer2's evolving architecture. The project remained short-lived, with activity tapering off by 2013 as its developer positioned it as an interim solution pending broader backend advancements. Both UMPlayer and SMPlayer2 were ultimately abandoned due to insufficient maintainer activity and the redundancy created by upstream improvements in SMPlayer, particularly the adoption of the mpv backend in late 2014, which incorporated mplayer2's key enhancements and resolved many compatibility issues that the forks had targeted. This integration rendered the specialized forks obsolete, as the mainline project evolved to support modern multimedia requirements without needing separate branches.

Integrations and Successors

SMPlayer has been integrated into media center applications such as Kodi, where it functions as an external player to handle video playback, enabling users to organize content in Kodi while utilizing SMPlayer's subtitle and support. The project's Qt-based graphical interface has influenced other open-source media players by exemplifying effective front-end designs for backends like mpv, as highlighted in compilations of mpv-compatible GUIs. In terms of successors, SMPlayer transitioned its primary multimedia engine from to mpv starting around 2015, with mpv now serving as the recommended backend for enhanced performance and format compatibility in recent versions. Community-driven extensions include SMPlayer Portable, a distribution packaged for easy deployment without installation, maintained through platforms like to broaden accessibility on Windows systems. As of 2025, forks continue to provide niche enhancements, such as the Windows ARM64 adaptation by minnyres, which supports modern hardware while preserving core functionality. Unlike abandoned forks such as UMPlayer, these ongoing efforts underscore SMPlayer's lasting role in open-source media playback, contributing GPL-licensed code that supports standards for cross-platform video handling via mpv.
