IINA

Overview

GitHubGitHub

IINA is an open-source video player designed specifically for macOS (11.0 and later), written in Swift and powered by mpv for media decoding. It covers all common features needed for video and audio playback, including subtitle loading, playlist management, and chapter navigation. For the interface, IINA supports multiple color schemes and customizable On-Screen Controller (OSC) layouts, while integrating macOS features like Force Touch, Picture-in-Picture, and Touch Bar. A dedicated Music Mode is provided for audio-only files. For subtitles, IINA supports online searching and smart matching of local subtitle files. Users can fully customize keyboard, mouse, trackpad, and gesture controls, as well as configure video and audio filters. Advanced users will appreciate compatibility with mpv configuration files and scripting, along with a command-line tool and browser extension. IINA supports feature expansion via plugins. Officially maintained plugins include Online Media for enhanced streaming and downloading, OpenSubtitles for searching and downloading subtitles, and User Scripts for running custom JavaScript code. The community has also contributed many plugins, such as AirPlay casting, Anime4K real-time anime upscaling, auto-skipping intros and outros, bilingual audio channel separation, danmaku display, and clickable dictionary-lookup subtitles. The project is open-sourced under the GPL-3.0 license and is actively developed. Users can get stable and beta versions from the GitHub Releases page or the official website, or download automatically generated nightly builds to try the latest features (which may be unstable). Building from source requires the latest version of Xcode, with the option to download pre-built libraries or manually build mpv dependencies.
