About IINA

IINA is a video player designed for modern versions of macOS, written in Swift and released under the GPL-3.0 license. It uses mpv as its playback engine, which gives it broad decoding capability, and wraps it in a native Mac interface that supports Force Touch, picture-in-picture and Touch Bar controls.

Everyday features include subtitles, playlists and chapters, video thumbnails, online subtitle searching with local subtitle matching, and an unlimited playback history. A standalone Music Mode is designed for audio files. The interface is customizable, with several color schemes and a movable on-screen controller, and keyboard, mouse, trackpad and gesture controls can all be remapped.

Advanced users can reuse mpv configuration files and scripts, and a command-line tool and browser extensions are provided. Stable and beta builds are available from the website and GitHub releases, while nightly builds are generated automatically and may be unstable. IINA suits Mac users who want a polished player for video and music that can be tuned in depth.
