Open Source Elixir Multimedia Software

Midarr is a minimal, lightweight media server built to complement tools like Radarr or Sonarr. Instead of reinventing the media management stack, it leverages existing setups and metadata providers to serve media files "fresh off the metal" without re-indexing or transcoding by default. It offers a sleek web interface with authentication, user profiles, real-time statuses, and experimental support for remuxing/transcoding and Chromecast compatibility.

Elixir WebRTC is an Elixir implementation of the W3C WebRTC API for building real-time communication features in Elixir applications. It gives developers a way to create peer connections, exchange media, and work with browser-compatible WebRTC behavior from the BEAM ecosystem. The project is especially useful for applications that need live audio, video, or data communication without leaving Elixir. It can support DataChannels through an optional SCTP dependency, which extends its usefulness beyond media streaming. Because it follows familiar WebRTC concepts, it can integrate with browser clients and other WebRTC-capable systems. Its main value is bringing WebRTC primitives into Elixir so developers can build real-time products with the fault tolerance and concurrency strengths of the BEAM.

Boombox is a high-level audio and video streaming tool built on top of the Membrane Framework. It is designed to make media transformations easier across common formats, containers, and streaming protocols. The project gives developers a simpler interface over lower-level multimedia pipelines, which can otherwise be complex to configure manually. Boombox is useful for Elixir projects that need to read, write, stream, transcode, or transform media without directly assembling every Membrane element. It can support applications such as media processing services, streaming tools, recording workflows, and format-conversion utilities. Its main value is making powerful Membrane-based multimedia processing more accessible through a cleaner, higher-level API.

Fishjam is a real-time multimedia streaming toolkit for building low-latency video and audio applications. The GitHub repository refers to the original open-source Fishjam media server, which was a general-purpose media server written in Elixir and is no longer actively maintained. The broader Fishjam project has since evolved into a platform for WebRTC-based live video, audio, and messaging infrastructure. It is designed for use cases such as video conferencing, live streaming, classrooms, telehealth, gameplay, collaboration, and interactive media products. Fishjam focuses on reducing the amount of WebRTC infrastructure that teams need to build themselves. Its main value is giving developers a practical foundation for real-time communication products with sub-second media delivery.

Mydia is a modern, self-hosted media management platform for tracking, organizing, and monitoring movies and TV shows, built with Phoenix LiveView for a highly responsive, real-time UI. It aims to function as a “personal media companion,” giving you a unified dashboard that pulls rich metadata and keeps your library information up to date as your collection grows. The system supports automation workflows around acquiring and managing media, including quality profiles and smarter release selection, so it can act as a hub rather than just a catalog. It integrates with common download clients and indexers, enabling an end-to-end workflow where requests, discovery, and acquisition are connected through a single interface. Mydia also supports multi-user setups with roles and request workflows, making it usable in households or shared servers without giving everyone full administrative power.

Algora TV is an open source Elixir/Phoenix application developed by Algora.io that powers Live Billboards—a platform for embedding in-video ads during livestreams. The project enables developers to monetize their live content while providing devtools companies a dynamic and non-intrusive way to reach audiences in real time. Built on top of the Phoenix framework, it leverages Elixir’s concurrency and scalability to handle streaming, ad management, and user interactions seamlessly. The system integrates with GitHub for authentication and uses Tigris for media storage and delivery, with optional support for services like FFmpeg, ImageMagick, and OBS Studio for livestream testing and video processing. The repository includes all setup instructions, from environment configuration to database initialization, making it accessible for developers to self-host or experiment locally.

membrane_core is the foundation of the Membrane multimedia framework for Elixir, providing the abstractions and runtime needed to build real-time audio and video pipelines. It models media processing as a graph of lightweight, supervised OTP processes—elements connected by links—so work is isolated, fault-tolerant, and easy to scale or reconfigure at runtime. The core defines a clear lifecycle and callback API for elements, plus concepts like buffers, events, and capabilities/format negotiation to keep components interoperable and type-safe. Back-pressure, scheduling, and time synchronization are handled by the framework, enabling low-latency streaming and precise playback control without ad-hoc concurrency code. Developers compose pipelines from reusable building blocks and can dynamically add, remove, or switch elements while the system is running.
