Real-time streaming infrastructure designed for low-latency broadcast delivery.
Real-time video delivery is fundamentally complex. Traditional streaming pipelines introduce latency, break under network variability, and rely heavily on external encoding tools. The challenge was to design a system that enables real-time broadcasting directly from the browser, while maintaining performance, reliability, and scalability.
Browser-Native Encoding
Using WebRTC to capture and encode streams directly from the client, bypassing external heavy-lifters.
Real-Time Transport
LiveKit SFU orchestration for low-latency distribution and efficient routing.
Format Conversion
Egress pipelines to convert WebRTC to RTMPS for legacy CDN compatibility.
Global Delivery
Cloudflare HLS transformation for scalable, regional playback.
Latency vs. Compatibility
WebRTC offers ultra-low latency but struggles with massive concurrent global fan-out compared to robust CDNs. Extracting the pure WebRTC feed and dynamically transcoding it into HLS via egress workers was necessary to support unbounded audiences while keeping the host's ingest latency sub-second.
Network Variability
Browser-native capture is vulnerable to the client's network state. We implemented aggressive adaptive bitrate streaming (ABR) and simulated edge fallback mechanics to ensure that upstream packet loss resulted in resolution degradation rather than connection drops.

"Building real-time systems requires more than connecting services — it requires understanding how data moves, transforms, and fails under pressure."
