Video: Deploying WebRTC In A Low-Latency Streaming Service

WebRTC is an under appreciated streaming protocol with sub-second latency. Several startups are working hard to harness this technology born by Google for use in video conferencing for live streaming.

When you look at the promised latencies, you can see why. CMAF, the lowest-latency protocol for live streaming using HLS-style chunked file delivery is gaining wider adoption and provides a very impressive latency reduction, however it typically stops at between 4 and 2 seconds. To get below a second, WebRTC is almost the only option out there.

In this talk, Millicast CTO Dr. Alex Gouaillard looks at the misunderstandings and misinformation are out there regarding WebRTC. Dr. Alex covers WebRTC now having ABR, using over multiple hops, the testing ecosystem and much more.

Dr. Alex also covers the lessons learnt over the last two years of development and implementation of the standard and finishes by looking to the future which will bring in QUIC, AV1 and Web ASM

Video: WebRTC: The Future Champion of Low Latency


With the continual quest for lower and lower latencies in streamed video, WebRTC is an attractive technology with latencies in the milliseconds rather than seconds. Limelight’s lowest latency offerings are based on WebRTC.

Alex Gouaillard from millicast explains the brief history and current status of WebRTC including which browsers are supported. After talking about optimisations that have been made, he talks about Bandwidth Adaptive Media and other use cases to be solved.

Supported codecs and, importantly, Scalable Video Coding support is discussed along with ways of implementing WebRTC. Alex also talks about the testing that’s gone in to the standard looking at bandwidth and latencies.

Lastly, a key question around WebRTC is ‘does it scale’ which is discussed before the conclusion.
