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 – 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.

Video: Best Practices for Advanced Software Encoder Evaluations

Streaming Media East brings together Beamr, Netflix BAMTECH Media and SSIMWAVE to discuss the best ways to evaluate software encoders and we see there is much overlap with hardware encoder evaluation, too.

The panel gets into detail covering:

  • Test Design
  • Choosing source sequences
  • Rate Control Modes
  • Bit Rate or Quality Target Levls
  • Offline (VOD) vs Live (Linear)
  • Discrete vs. Multi-resolution/Bitrate
  • Subjective vs. objective measurements
  • Encoding Efficiency vs Performance
  • Video vs Still frames
  • PSNR Tuning
  • Evaluation at Encode Resolution Vs Display Resolution

Video: HOW TO: Building a More Robust Cloud Encoder With FFMPEG & More


A great ffmpeg how-to from Jan Ozer followed by cloud deployment advice from RealEyes Media.

Starting from some of the basics of the ffmpeg command line, working up to HLS packaging, Jan Ozer offers advanced alternatives along side the familiar commands.
By taking control of your own encoding and packaging, you can greatly reduce cost and maintain high adaptability and agility to meet your needs now and in the future. When working with cloud encoding, there are several transcoding and packaging options, and the APIs for these options will change over time. David Hassoun and Jun Heider, from RealEyes Mediatalk talk about how to build a more dynamic cloud encoder that can use the best tool for a specific job by decoupling the tools from the core application, as well as how to mix and match multiple operations concurrently on a single encoding task. Operations include WebVTT and AAC sidecar manifests, DASH assets, metadata, video quality, and stream muxing/demuxing. This session covers some of the strategies we’ve used to handle dynamic cloud encoding and packaging for live and VOD delivery.

Video: Comparing and Choosing The Best HEVC Codec


On-demand Presentation
Content distributors and aggregators adding HEVC to their delivery pipeline will have plenty of codec options, but who has the time to evaluate their features, output quality, and performance?

No worries—codec specialist Jan Ozer has done the work for you. He’s evaluated leading contenders like x265, MainConcept, Beamr, Intel, and NTT and he’ll share his results. You’ll walk away from this session with a much clearer picture of the strengths and weaknesses of your HEVC encoding options for VOD streaming.
