Video: Deploying CMAF In 2019

It’s all very good saying “let’s implement CMAF”, but what’s implemented so far and what can you expect in the real world, away from hype and promises? RealEyes took the podium at the Video Engineering Summit to explain.

CMAF represents an evolution of the tried and tested technologies HLS and DASH. With massive scalability and built upon the well-worn tenants of HTTP, Netflix and a whole industry was born and is thriving on these still-evolving technologies. CMAF stands for the Common Media Application Format because it was created to allow both HLS and DASH to be implemented in one common standard. But the push to reduce latency further and further has resulted in CMAF being better known for it’s low-latency form which can be used to deliver streams with five to ten times lower latencies.

John Gainfort tackles explaining CMAF and highlights all the non-latency-related features before then tackling its low-latency form. We look at what it is (a manfest) and where it came from (ISO BMFF before diving in to the current possibilities and the ‘to do list’ of DRM.

Before the Q&A, John then moves on to how CMAF is implemented to deliver low-latency stream: what to expect in terms of latency and the future items which, when achieved, will deliver the full low-latency experience.

Video: Reducing Latency & Startup Times

Low latency and fast startup times are KPIs for most streaming video producers, particularly for live events. In this talk from Streaming Media west, you will learn how to achieve the low latency live streaming.
David and Jun show the importance of measuring startup time, latency, and network overhead and with Jan Ozer, they show you how to get latency down by:
• reducing fragment sizes, using hybrid fragment sizes;
• specifying first variant retrieved;
• controlling the number of fragments retrieved before playback starts;
• and opening a persistent connection between player.

You’ll learn the most effective strategies for minimizing startup time and latency without swamping your network with additional HTTP requests, and what you’ll need to do to implement them in your encoding and delivery workflows.
