REDPlayer 是一款由小红书自主研发的跨平台(支持 Android、iOS、HarmonyOS 等平台)播放器。不同于行业其他播放器，REDPlayer 具有结构简单、耦合度低、功能边界清晰等特点，提供了多种接入方式，技术人员可根据需要灵活选择，既可快速集成SDK使用，也可基于源码进行定制开发。
REDPlayer 的宗旨是让开发者可以快速明确地了解播放器的基本构造，并可根据个人需求进行简单扩展，满足不同用户的多样需求，可作为学生学习的基础工具，也可作为企业的商用平台。
REDPlayer 支持点播、直播场景下的多种协议和格式(如 HLS、MP4、FLV 等)，并可二次扩展更多协议(如：RTC 等)。每个模块均是解耦的，开发者可以根据需要挂载自定义模块，如自研解码器、渲染器等。
