NymphCast is an audio and video casting system that turns Linux-capable hardware (such as SBCs) into a network receiver for TVs, speakers, or Hi‑Fi systems. It streams local media files, media server content, and internet media to a NymphCast server, controlled from a client device or optional on-screen GUI.
Key Features
- Receiver server for audio-only or audio+video playback, including optional “Smart TV” style GUI mode
- Streaming from client devices, from URLs, and from NymphCast MediaServer instances
- Multi-room synchronized playback (experimental)
- Broad codec support via FFmpeg for decoding and playback
- Extensible “apps” system (preview/experimental) using AngelScript for adding services and custom UI elements
- Client ecosystem including a CLI client and a Qt-based graphical client (NymphCast Player), plus a client SDK library
Use Cases
- Turn a Raspberry Pi or small Linux box into a network music receiver for powered speakers
- Add a casting endpoint to a TV for network video playback controlled from desktop or Android
- Build custom casting-enabled applications using the client SDK
Limitations and Considerations
- Some major features are explicitly experimental (multi-room playback, GUI mode, apps) and may be incomplete or less stable
- Video capability and performance can depend heavily on platform hardware decode support
NymphCast provides a flexible, extensible casting receiver that can be deployed on many platforms and controlled by dedicated clients. It is well-suited for DIY audio/video endpoints and for integrating casting into custom applications.
