mpv was forked by Vincent Lang, also known as wm4, in 2012 from mplayer2, which was forked in 2010 from MPlayer.[8] The motive for the fork was to encourage developer activity by removing unmaintainable code and dropping support for very old systems. As a result, the project had a large influx of contributions.[9]
mpv has had several notable changes[11] since it was forked from MPlayer; the most obvious at first glance is the addition of a minimal on-screen controller (OSC) to offer basic mouse interactions. This was intended to make interaction easier for new users and to enable precise and direct seeking.
Video websites: By using yt-dlp, mpv natively supports playback of high-definition video (HD) content and audio on YouTube and over 1000 other supported sites.[12] This allows mpv to replace site-specific video players based on HTML5.
Audio scaling algorithm: The player is equipped with a scaletempo2 parameter for speed changing at constant pitch, for which it uses the Waveform Similarity Overlap-and-add (WSOLA) algorithm, citing more smoothness than the original scaletempo used in the original mplayer, and rubberband.[16]
Improved client API: Beyond working as a stand-alone media player, mpv is designed to be used directly by other applications through a library interface called libmpv. Plex is an example of an application that makes use of this functionality.[17] As a result, all mpv code is required to be thread safe. This form of player control, along with a JSON IPC mechanism, replaces MPlayer's "slave mode".
Encoding subsystem: mpv includes a new video encoding mode that can be used to save files being played under different formats. This allows mpv to work as a transcoder, supporting many video formats.[18] This feature serves as a direct replacement for the MEncoder component of MPlayer, which was a separate program rather than being built into the player.
Lua scripting: mpv's behavior and functions are customizable via use of small programs written in the Lua scripting language, which can be used for tasks like cropping video, providing a graphical user interface (GUI) or automatically adjusting the display's refresh rate.[19]
Like the original MPlayer, mpv is still primarily a command-line application. However, it also has a basic on-screen controller (OSC) to permit limited mouse control; this OSC is still not a full-featured GUI, and there are a number of graphical front-ends available, which use GUI widgets for Qt, GTK, or other toolkits to provide a more complete UI.
The following are some open source front-ends of mpv (based on "libmpv" or the command-line version of mpv) which try to provide more features and a more user-friendly interface than mpv, and/or better integration with various operating systems or desktop environments.[20]
Baka MPlayer - media player on Windows, Linux, and macOS although macOS version requires the user to compile from source, with Qt5 widgets, written in C++. Its main goal is uncluttered, simple design.[21] Its development stalled in January 2017 in favor of another mpv frontend by the same developers, Mochi Player, which is not yet complete.
C-Play - is a video/media player developed for cluster environments where you need multiple computers and/or displays to run your video/image content on. The displays could be flat or curved, and the video content 180 fulldome / fisheye, 360 equirectangular or equiangular cubemap or regular flat content, as well as stereoscopic (Side-by-side or Top-Bottom). Installers and testing is primarily performed for Microsoft Windows, but the code is cross-platform, written in C++ with Qt6/Qt5 QML UI.[22]
Deepin Movie - for Linux - Written by and default video player for the Chinese Deepin distro and desktop environment.[23]
GNOME MPV (Celluloid) 0.18 with its preferences
Celluloid (formerly GNOME MPV) - for Linux - based on GTK. Its goal is to be a simple GTK-based graphical interface for mpv that meets the GNOME Human Interface Guidelines.[24]
Haruna Media Player - for Linux, Windows - based on Qt/QML. A KDE media player project with YouTube support and customizable shortcuts. [25]
IINA - macOS 10.10+ media player with native macOS Cocoa interface. It is a full-featured native macOS graphical interface for mpv that makes use of new features in the most recent versions of macOS. mpv config file and script system are also integrated.[26]
ImPlay - Cross-platform media player with an interface built with the imgui interface library, it includes a context menu and command palette to interact with the player.[27]
Media Player Classic Qute Theater (mpc-qt) - Linux and Windows media player with Qt5 widgets, written in C++. Its goal is to reproduce and ultimately improve upon the functionality of Media Player Classic Home Cinema (mpc-hc), a Windows-only program, as a cross-platform mpv-based multimedia player that also works on Unix-like operating systems like Linux.
mpv.net - Windows media player with native Windows interface. Its goal is to provide the standard mpv OSC interface on Windows along with a customizable Windows context menu, C# scripting, and a Managed Extensibility Framework (MEF) for addons.[29]
OvoPlayer - Linux and Windows music player that supports many backends, based on LCLwidgetsets, written in Pascal. Its goal is to be a flexible audio player that supports as many audio engine backends like mpv as possible.[30]
Sugoi Player - media player on Windows (that might work on Linux and macOS but those are untested) forked from Baka MPlayer, with Qt5 widgets, written in C++. It aims to improve upon and continue development of an mpv frontend based on Baka MPlayer, since Baka MPlayer's development stalled in January 2017.[32]
xt7-player-mpv - Linux media player with Qt5 or Qt4 widgets, written in Gambas 3 (a dialect of BASIC). Its goal is usability, and a variety of extra features like YouTube and SHOUTcast integration, media tagging, library and playlist management, as well as adding more features beyond that.[33]
