Introduction - Monibuca Streaming Media Server Engine

What is Monibuca?

Monibuca (abbreviated as m7s) is a high-performance streaming media server engine. Version 6 has been completely rewritten from scratch in Rust, pushing performance to the extreme while maintaining a flexible plugin-based architecture.

Monibuca is not just a streaming server — it is an engine. It provides comprehensive streaming media processing capabilities, allowing developers to rapidly build streaming applications tailored to various business requirements through its plugin system.

Core Features

Multi-Protocol Support

Monibuca natively supports mainstream streaming protocols, ready to use out of the box:

Protocol	Publish	Subscribe	Description
RTMP	✅	✅	Classic low-latency publishing protocol
RTSP	✅	✅	Commonly used for surveillance devices
HTTP-FLV	-	✅	HTTP long-connection streaming
HLS	-	✅	Widely compatible segmented protocol
WebRTC	✅	✅	Based on WHIP/WHEP standards, ultra-low latency
SRT	✅	✅	Secure Reliable Transport protocol
GB28181	✅	✅	Chinese national standard for video surveillance networking
WebTransport	✅	✅	Next-generation transport protocol based on QUIC

Zero-Copy RingBuffer

Featuring a proprietary zero-copy ring buffer design, audio and video data written by publishers is read directly by all subscribers through references without memory copying. This design results in extremely low memory overhead when a single stream serves a large number of concurrent subscribers.

Dispatcher Architecture

An event-driven architecture based on the Dispatcher enables efficient stream management and distribution. Each stream has its own Dispatcher instance responsible for coordinating data flow between publishers and subscribers.

Plugin System

All protocols and features in Monibuca are implemented as plugins, supporting both static compilation and dynamic loading modes:

Static compilation: Select required plugins via feature flags, compiled into a single binary
Dynamic loading: Load .so / .dylib plugins at runtime for flexible extension

Cluster Support

Built-in cluster plugin supporting multi-node deployment and cross-node stream distribution, easily handling large-scale concurrent scenarios.

Full-Stack Monitoring & Operations Dashboard

V6 includes a complete monitoring system spanning from stream-level to site-wide, with no third-party tools required:

Stream-level real-time monitoring: Per-frame waveforms + bitrate/framerate/GOP trend charts with live SSE push
Room-level quality analysis: Sender-receiver pair analysis with bitrate, freeze, packet loss, and resolution comparison
Live operations dashboard: Site-wide real-time overview, 7-day trends, popularity ranking, risk detection
Three-tier reporting: Heartbeat (real-time quality) + Leave (session snapshot) + KV (event counters)

Through the Admin dashboard, operations teams can monitor site-wide live streaming status in real time, while developers can quickly diagnose audio/video quality issues through bitrate and framerate analysis. See Monitoring & Operations for details.

V6: Complete Rust Rewrite

V6 is a milestone release for Monibuca, fully migrated from Go to Rust, bringing a quantum leap in capabilities:

Extreme performance: Rust’s zero-cost abstractions and memory safety guarantees deliver significantly higher throughput
Memory safety: Data races and memory leaks are eliminated at compile time, ensuring stable server operation
Lower latency: No GC pauses, making audio/video processing latency more predictable
Full-stack monitoring: Built-in three-tier reporting + three dashboards, real-time observability for bitrate/framerate/freeze
Full-stack ecosystem: Engine + Admin dashboard + monitoring dashboards + Web player + Web SDK, all developed in-house

Media Processing: Audio transcoding, video snapshots, MP4 recording, HLS segmentation
Edge Nodes: Lightweight deployment with cluster cascading, ideal for edge computing scenarios

Open Source & Ecosystem

Monibuca open-sources the monibuca-sdk plugin development SDK, allowing developers to freely develop custom plugins that run via dynamic loading or WASM sandbox mode.

Monibuca also provides a complete full-stack ecosystem:

Engine: Pre-compiled binaries or Docker images, ready to use out of the box
Admin dashboard: In-house visual management interface for stream monitoring, configuration management, and operations dashboards in one place
Monitoring dashboards: Built-in Stream Detail, Room Report, and Live Dashboard for visual bitrate/framerate troubleshooting
Web player: In-house Web player supporting HTTP-FLV, HLS, WebSocket-FLV, and other protocols
Web SDK: Frontend rapid integration SDK, covering the entire pipeline from publishing to playback

For enterprise-level requirements, Monibuca offers commercial licensing and technical support services, including:

Enterprise features (authentication, encryption, advanced cluster capabilities)
Dedicated technical support and consulting
Custom development services
