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.

Video – Live Streaming with VP9 at Twitch TV

Tarek Amara from Twitch explains their move from a single codec (H.264) to multiple codecs in order to provide viewers an optimal viewing experience.

In this session, Tarek shares findings on VP9’s suitability for live streaming and the technical and industrial challenges such move involves. Covering:

  • VP9 encoding performance,
  • Device and player support,
  • Bandwidth savings,
  • The role of FPGAs
  • plus an overview of how the transcoding platform need to change to enable VP9 encoding and delivery at scale.

This presentation is from the Video Engineering Summit at Streaming Media West 2018.
