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

Webinar: Advanced Encoding & Transcoding with the Experts

Thursday 27th September 2018, 19:00 BST / 11am PT / 2pm ET

Encoding and transcoding are at the heart of every video service and solution, and the codec and format landscape has never been more crowded. Publishers are wringing the most efficiency out of H.264 while making the move to HEVC/H.265 and AV1—and keeping an eye on other proprietary codecs. On top of all that are considerations like video optimization, bitrate ladders, and per-title encoding.

Join this expert panel as they discuss the latest in encoding and transcoding, including the following:

  • The state of the art in encoding efficiency in 2018
  • How per-title encoding and machine learning can increase quality and decrease delivery costs
  • How to build flexible and cost-effective encoding solution
  • The latest developments in video encoding platforms and infrastructure
  • The benefits of contribution to distribution encoding and transcoding
  • The next big advances in encoding and transcoding, including AV1

Video: Comparing AV1, VP9, HEVC, & H.264

Comparing AV1, VP9, HEVC and H.264 is quite a task, but Streaming Media’s Jan Ozer is here to take us through it. From MPEG royalties to VP9 browser compatibility, from the AV1 roadmap to HEVC-enabled HLS, this is a comprehensive look at real world usage of the top four codecs.

This is a key topic because many content distributors and aggregators still use H.264 as their primary, if not exclusive, codec, but the bandwidth savings promised by newer, more powerful codecs are alluring. Those considering a switch must evaluate at least three options: HEVC, VP9, and AV1.

In this session, codec specialist Jan Ozer evaluates the quality of these codecs and compares them to H.264. Learn how much bandwidth you can save with each, and how the newer codecs compare from quality and implementation perspectives.

Video: How to Fine Tune your Adaptive Encoding Groups with Objective Quality Metrics


In this on-demaind video, Streaming Learning Center’s Jan Ozer explains objective metrics to us and how they can be used to build better ABR ladders.

Choosing the number of streams in an adaptive group and configuring them is usually a subjective, touchy-feely exercise, with no way to really gauge the effectiveness and efficiency of the streams. However, by measuring stream quality via metrics such as PSNR, SSIMplus, and VQM, you can precisely assess the quality delivered by each stream and its relevancy to the adaptive group.

This presentation identifies several key objective quality metrics, teaches how to apply them, and provides an objective framework for analyzing which streams are absolutely required in your adaptive group and their optimal configuration.

Webinar: Foundational Concepts: Video Compression, Processing and Delivery


On demand webinar from AWS Elemental covering some streaming basics.

In this webcast, you will:
• Learn how to create and deliver video over the internet
• Understand video codecs, containers, popular delivery methods and content delivery networks
• Consider methods, including adaptive bitrate streaming, that enable high-quality video to be delivered to a wide range of internet-connected devices
• Learn about the latest trends in video compression and delivery

Increasing smartphone subscriptions and data volumes per subscription are driving rapid growth in mobile data traffic, much of which is video content. According to multiple industry reports, these trends will continue for the near future, and by 2020, 75 percent of the world’s mobile data traffic will be video according to the Cisco Visual Networking Index. Technical and business leaders at organizations that aim to expand offerings using video need to understand the complexities of delivering premium viewing experiences to consumers.

Video: Improving Video Quality and Reducing Bandwidth by Going Beyond Fixed Bit-Rate ABR Recipe


This panel discusses real-world methods, techniques, and solutions for moving beyond traditional fixed bit-rate ABR profiles to a content adaptive approach, where the encoding bit-rate is determined by the needs of the video vs. a pre-determined recipe. Come hear innovative thinking that, if adopted, can yield a 20% or potentially higher savings while improving the quality of your video encodes.
