MPlayer OSX Extended
MPlayer OSX Extended is a free, open-source video player for macOS that plays a wide variety of audio and video formats without requiring additional codec installations. It is built on the MPlayer backend and provides an alternative to the system's default media player, offering frame-accurate playback and support for subtitles, streaming, and advanced playback controls. The app was popular among users who needed compatibility with less common video codecs or streaming protocols.
AI Recommendation
1 suggestionMPlayer OSX Extended has been discontinued and is no longer supported by its developer. The project appears to have reached end-of-life status, meaning no further updates or maintenance are being provided. While the app may still run under Rosetta 2 today, it will stop working entirely when Apple removes Rosetta 2 in macOS 28 (September 2028). You should plan to migrate to an actively maintained video player before that deadline. VLC is the most direct replacement — it is free, open-source, plays virtually every format that MPlayer supported, and has a confirmed native Apple Silicon build available now. Alternatively, Infuse offers a modern native interface with broad codec support if you prefer a more polished commercial option.
