Red5 Server
This project is a real-time communication and media streaming server designed for broadcasting, recording, and distributing audio and video content. It functions as a live streaming server and an RTMP media server, providing the infrastructure necessary to deliver real-time media to multiple concurrent viewers over a network.
The system distinguishes itself through a multi-protocol media gateway that supports RTMP, E-RTMP v2 for modern codecs like HEVC and AV1, and HTTP media tunneling to bypass restrictive firewalls. It further acts as a real-time communication platform by synchronizing shared state objects across connected clients and pushing asynchronous updates via server-sent events.
The server covers broad capability areas including media session management, live stream recording, and video-on-demand delivery. It incorporates security features such as TLS/SSL encryption and protocol traffic validation, while using hierarchical user scoping to control data visibility across global, web, and room levels.
Administrative utilities allow the server to be deployed as a daemon on Linux and Windows for background execution.
Features
- Live Streaming Servers - Provides a complete system for delivering real-time media content to multiple concurrent viewers over a network.
- Real-Time Media Streaming - Broadcasts live audio and video to multiple concurrent viewers over a network using protocols like RTMP and E-RTMP.
- Client-Server State Synchronization - Maintains consistent state across multiple concurrent client connections using a server-side state manager.
- Media Servers - Acts as an RTMP media server for broadcasting, recording, and distributing real-time audio and video streams.
- Video Streaming Servers - Provides a high-performance streaming implementation using the Enhanced RTMP v2 specification for modern codecs like HEVC and AV1.
- Media Protocol Gateways - Translates between RTMP, E-RTMP, and HTTP to deliver real-time audio and video across different network environments.
- Real-time Communication Servers - Functions as a real-time communication platform by synchronizing shared state and pushing asynchronous events via server-sent events.
- Real-Time Synchronization - Maintains consistent shared data objects across multiple connected clients to coordinate application state in real time.
- Streaming Session Managements - Manages the lifecycle of streaming sessions by cleaning up stale connections and sending keep-alive signals.
- RTMP Protocol Support - Delivers audio and video content using the RTMP protocol and its secure variants.
- State Consistency Controllers - Maintains consistent state across multiple client connections using a shared object implementation.
- Stream Recorders - Captures incoming real-time media streams and saves them as files for archival and later playback.
- Media Distribution Networks - Delivers real-time audio and video content across a network to all connected clients.
- Media Stream Recording - Captures incoming real-time media streams and saves them as files for archival and later playback.
- E-RTMP v2 Support - Supports the Enhanced RTMP v2 specification for high-performance video streaming using HEVC and AV1 codecs.
- Stream Publishing - Enables broadcasting of real-time media from a single source to multiple concurrent viewers over a network.
- Session Management - Controls the entire lifecycle of media streams, from initial broadcasting to recording and playback.
- Video Streaming - Streams pre-recorded video content to users using dedicated storage and delivery infrastructure.
- Room-Based Message Routing - Directs messages to specific groups, rooms, or application segments to isolate communication between users.
- Connection Lifecycle Managers - Controls session lifecycles by tracking active sockets and using keep-alive signals to prune stale client connections.
- HTTP Tunnels - Wraps media streams in HTTP packets to bypass restrictive firewalls and proxies.
- Protocol Traffic Validations - Protects against stream confusion and overflow attacks through chunk size validation and header checking.
- Real-Time Data Streams - Maintains persistent connections to distribute live audio, video, and data updates to clients.
- Real-Time Messaging - Sends server-to-client updates using Server-Sent Events with integrated connection management and keep-alive signals.
- Server-Sent Events - Pushes asynchronous updates and real-time messages from a server to clients using non-blocking connections.
- Stream Encryption and Decryption - Secures real-time media transmission using TLS/SSL encryption to protect data moving between clients and the server.
- Media Plugin Architectures - Customizes media handling and streaming behavior through a specialized media plugin system.
- Plugin-Based Logic Extensions - Allows custom media handling and streaming behavior by loading external modules into the server runtime.
- Hierarchical Scopes - Organizes connections into global, web, and room levels to isolate data visibility and target specific user groups.
- Server Administration - Manages the lifecycle of media sessions, client connections, and secure stream delivery through a central server.
