IINA+ is a free, open-source macOS application that extends the IINA media player with online streaming and danmaku support. It allows users to watch videos and live broadcasts from popular Chinese streaming platforms through IINA. Supported services include Bilibili, Bangumi, Douyu, Huya, Douyin, and several live streaming websites. Its danmaku integration displays synchronized viewer comments directly over video playback. The application handles stream extraction and video decoding for compatible platforms. It can also check the live status of supported streaming channels. Platform compatibility varies, with some services supporting video playback but not danmaku comments. Built with Swift, IINA+ provides a desktop viewing alternative for users who prefer IINA over browser-based streaming.
