Distributed RTSP Streaming Orchestration with Auto-Scaling
The surveillance platform needed a reliable, scalable system to manage hundreds of camera streams with automatic lifecycle management, ensuring streams are available on demand without wasting resources.

Le DĂ©fi
Managing streaming infrastructure for many cameras presented operational challenges:
- Manually provisioning streaming servers for each camera was unsustainable
- Idle streams wasted compute resources and bandwidth
- Cloudflare and CDN integration required HLS conversion from RTSP
- User-scoped access control needed to ensure tenants only saw their cameras
Notre Solution
We built an orchestration layer that dynamically provisions, monitors, and cleans up MediaMTX streaming containers based on demand.
Architecture
- Orchestrator API: FastAPI microservice for stream lifecycle management
- Container Engine: Docker-based MediaMTX container provisioning
- Authentication: Supabase JWT for user-scoped camera access
- CDN Proxy: Cloudflare Workers for HLS delivery
- Health Monitoring: Periodic health checks with automatic recovery
Lifecycle Management
- On-Demand Provisioning - Streaming server created when user requests a camera feed
- RTSP-to-HLS Conversion - MediaMTX handles protocol conversion for browser playback
- Health Monitoring - Periodic checks ensure server responsiveness
- Auto-Cleanup - Idle servers terminated after configurable timeout
- Recovery - Unhealthy servers automatically restarted
Key Features
- User-Scoped Access - Each tenant sees only their authorized cameras
- Dynamic Scaling - Containers spun up and down based on viewer demand
- Quality Control - Per-stream FPS (1-60) and resolution (low/medium/high/ultra) settings
- Snapshot API - Timestamp-precise frame capture from live streams
- CDN Integration - Cloudflare Workers proxy for global low-latency HLS delivery
- RTSP Caching - Intelligent caching of camera connection details to minimize API calls

Traitement de factures assisté par l'IA avec OCR et intégration QuickBooks
Une entreprise de taille moyenne, traitant des centaines de factures fournisseurs chaque mois, devait éliminer la saisie manuelle des données en extrayant automatiquement les données des factures à l'aide de l'IA/OCR et en les synchronisant directement dans QuickBooks pour la tenue de livres et le suivi des paiements.
Insertion d'annonces côté client (CSAI) avec analyse des marqueurs SCTE-35 et intégration de lecteurs multiplateformes
Une plateforme de streaming vidéo devait implémenter l'insertion d'annonces côté client (CSAI) sur les applications web, mobiles et de télévision connectée — permettant des expériences publicitaires personnalisées au niveau de l'appareil avec un support complet d'interaction publicitaire (superpositions cliquables, bannières complémentaires, boutons de saut) que l'insertion côté serveur ne peut pas offrir.
Questions fréquemment posées
MicrocosmWorks built a multi-region orchestration layer where edge relay nodes at each physical location pull RTSP streams locally, transcode as needed, and forward them to the central platform via encrypted tunnels. This architecture eliminates the need for direct internet-exposed camera access, reduces WAN bandwidth by applying intelligent frame sampling at the edge, and maintains stream continuity even during network fluctuations between sites.
MicrocosmWorks implemented schedule-aware auto-scaling that pre-provisions processing capacity based on historical stream patterns, combined with reactive scaling that responds to real-time stream count changes within 30 seconds. The system scales down aggressively during off-peak hours to minimize cloud compute costs, and uses warm standby pods that can accept new streams instantly without the cold-start delay of provisioning new GPU instances.
MicrocosmWorks designed an admission control system that queues incoming stream connections and distributes them across available processing nodes using a weighted round-robin algorithm that accounts for each node's current CPU, GPU, and memory utilization. Streams are prioritized based on configurable rules, so high-priority cameras like entry points always get processing capacity before lower-priority feeds.
Yes, MicrocosmWorks built ONVIF discovery and RTSP pull adapters that connect to existing NVRs and VMS platforms, treating them as stream sources without requiring any changes to the existing recording infrastructure. The orchestration layer can also receive re-streamed feeds from popular VMS systems like Milestone and Genetec, allowing enterprises to add AI analytics capabilities to their current surveillance investment.
MicrocosmWorks delivers distributed streaming orchestration solutions at rates between $30-$50/hr, with a production-ready MVP typically requiring 3-4 months of development depending on the number of edge locations and integration requirements. This is substantially more cost-effective than enterprise video platform licenses that charge per-stream fees, especially at scale beyond 100 concurrent streams.
