Detailed Introduction

NymphCast is an open-source software solution that transforms commodity hardware (like Raspberry Pi or a PC) into a networked audio and video receiver. It allows you to stream local files, network media, or internet URLs from a client device (phone, computer) or a dedicated media server. The server supports multi-room synchronized playback, subtitle selection, and all codecs supported by ffmpeg. Experimental features include a Smart TV GUI mode and an AngelScript app system for extending functionality. It's a lightweight, privacy-respecting alternative to proprietary solutions like Chromecast or AirPlay, with no vendor lock-in.
