Video: Using CMAF to Cut Costs, Simplify Workflows & Reduce Latency

There are two ways to stream video online, either pushing from the server to the device like WebRTC, MPEG transport streams and similar technologies, or allowing the receiving device to request chunks of the stream which is how the majority of internet streaming is done – using HLS and similar formats.

Chunk-based streaming is generally seen as more scalable of these two methods but suffers extra latency due to buffering several chunks each of which can represent between 1 and, typically, 10 seconds of video.

CMAF is one technology here to change that by allowing players to buffer less video. How does this achieve this? An, perhaps more important, can it really cut costs? Iraj Sodagar from NexTreams is here to explain how in this talk from Streaming Media West, 2018.

Iraj covers:

  • A brief history of CMAF (Common Media Format)
  • The core technologies (ISO BMFF, Codecs, captions etc.)
  • Media Data Object (Chunks, Fragments, Segments)
  • Different ways of video delivery
  • Switching Sets (for ABR)
  • Content Protection
  • CTA WAVE project
  • Wave content specifications
  • Live Linear Content with Wave & CMAF
  • Low-latency CMAF usage
  • HTTP 1.1 Chunked Transfer Encoding
  • MPEG DASH

Video: SCTE-35 In-band Event Signalling in OTT

Alex Zambelli from Hulu presents SCTE-35 at the Seattle Video Tech Meetup.

Alex looks at what SCTE and SCTE-35 are and introduces ad insertion. With the foundation in place, he then looks through the message structures to show the commands and descriptors possible.
Finishing off with SCTE-35 signalling in MPEG-DASH and HLS, Alex covers the topic admirably for live streaming!

Webinar: Latency Still Sucks – So What Can You Do About It Today?

Date: Thursday 6th December, 2018. 11AM PT / 2PM ET / 19:00 GMT

Nobody wants to find out about a big play or major news event on Twitter before they see it in their video stream, so reducing latency is crucial for OTT services’ success. Likewise, ultra-low latency is crucial for interactive streaming applications. Depending on your use case, a few seconds of latency might be fine, or you might need to try to hit that sub-second target.

Learn which technologies and solutions are best for your business, and make sure your viewers get their video on time, every time. In this webinar, you’ll learn the following:

  • Why it’s important to evaluate and improve latency end-to-end, including software and services, encoder, platform, and player
  • How to decide which technology and solution is best for your use case (e.g. CMAF, HLS/DASH, WebRTC, Websocket)
  • How chunked CMAF offers a standards-based approach that allows latency to be decoupled from segment duration
  • How chunked CMAF leverages existing CDN HTTP capacity to provide low-latency solutions at high scale
  • How WebRTC can be used to deliver live video sub-second latency at scale, and provide rich, interactive experiences for live streaming applications
  • How a single misconfigured component can undo any other effort to achieve low latency
  • How integrated solutions create new business opportunities for low latency interactive use cases
  • How to achieve low latency across all platforms and devices

Video: Low-Latency DASH streaming

From VideoLAN’s Video Dev Days 2018, Romain Bouqueau from GPAC and FireKast discusses MPEG DASH and how this helps us with low-latency streaming. Romain starts by looking at latency in Adaptive Streaming Workflow and then covers 4 false assumptions in streaming. We are walked through all the different points that latency can occur and we see how to reduce each before looking at the drawbacks.

Webinar: Sub-Second Global Live Streaming

Viewers are increasingly watching live sports and other realtime events online, but the inherent delay in traditional online streaming often means they learn about an important play from social media before they are able to see it. Delivering true realtime global online streaming requires a new approach.

Video delivery experts from Limelight Networks present ways to deliver broadcast quality low-latency live streams, including the ability for viewers to watch live video with less than one second of latency on standard web browsers—without special plug-ins. Also discussed is how to integrate live video and interactive data to open up new workflows in sports, gaming, auctions, and more and make live viewing a more interactive social experience.

Join this webinar for:
• Latest market data on the evolving viewer expectations for online
• Delivering low-latency live video with HLS and DASH chunked streaming techniques
• Realtime global live streaming using WebRTC
• How integrated live bidirectional data sharing can help open up new business opportunities
• and much more!

Video: The Quest for Low-Latency Live Video


A great discussion from Streaming Media East discussing the battle to achieve Low-Latency Live Video by speakers from BAMTECH, Limelight and Red5Pro.In this session, learn about the pros and cons of various technologies on both the contribution and delivery side of lowlatency streaming, including small chunk size HLS/DASH, WebRTC, WebSockets, QUIC, SRT, and CMAF:

  • What does ‘Low Latency’ mean? Realtime? Are Cable & TV low-latency?
  • How do you synchronise OTT with Data and TV
  • Where is latency introduced? Which buffers have the biggest impact?
  • How can you fight rebuffing and which metric is the most useful?
  • Pros and Cons of WebRTC
  • How to stream 4K/VR?
  • Plus Q&A
