Video: Running live video with FFmpeg

San Francisco Video Tech welcomes Haluk Ucar talking about live video streaming. How do you encode multiple resolutions/bitrates efficiently on CPUs and maximise the amount of channels? Is there value in managing multiple encodes centrally? How can we manage the balance between CPU use and VQ?

Haluk discusses a toolset for Adaptive Decisions and looks at Adaptive Segment Decisions. Here he discusses the relationship between IDR frames and frequent Scene Changes.

Haluk covers a lot and finishes with a Q&A. So if you have an interest in Live Streaming, then Watch Now!

Webinar: Edge Computing and Video Delivery

Date: Thursday 28th March, 2019
Time: 10am PDT / 1pm EDT / 17:00 GMT

Whether or not edge computing is the next generation of cloud technology, the edge plays a vital role in the streaming video experience. The closer a video is stored to the requesting user, the faster the delivery and better the experience. But, streaming also provides a lot more opportunity for interactivity, engagement, and data collection than traditional broadcast television. That means as the edge grows in compute capacity and functionality, it could enable new and exciting use cases, such as AI, that could improve the viewer experience. In this webinar, we’ll explore the state of edge computing and how it might be leveraged in streaming video.

Webinar: What to See at NAB

Date: Friday, March 29th 2019
Time: 11am PT / 2pm ET / 18:00 GMT

NAB is coming around again and the betting has started on what the show will bring. Whilst we can look to last year for hints, here editors from Streaming Media come together to discuss the current trends in the industry and how they will be represented at NAB.

Some highlights of the conversation will be:

  • What HEVC solutions people are showing – the ongoing codec wars are captivating to most people as AV1 tries – and gradually succeeds – to break its ‘too slow’ label, whilst HEVC continues to grow acceptance with its ‘ready to deploy’ label despite the fees.
  • UHD production and delivery – We know that production houses prefer to capture higher resolution as it increases the value of their content and gives them more options in editing. But how far is UHD developing further down the chain. Is it just for live sports?
  • Live Streaming – SRT is bound to keep making waves at NAB has Haivision plans its biggest event yet discussing the many ways it’s being used. SRT delivers encrypted, reliable streams – while there are competitors, SRT continues to grow apace.
  • NDI – This compressed but ultra low latency codec continues to impress for live production workflows – particularly live events, though it’s not clear how much – if at all – it will make its way into top-tier broadcasters.

Much more will be on the cards, so register now for this session on Friday March 29th.

Webcast: 3-Part Webcast – Resilient Live Streaming Video

Date: 26th March 2019
Time: 8am, 9am & 10am EDT – 15:00, 16:00 & 17:00 GMT

AWS is synonymous with cloud computing and whether you use it or not, knowing how to do things in AWS reaps benefits when trying to understand or implement systems in a cloud infrastructure. Knowing what’s possible and what others are doing is really useful, so whilst I don’t usually cover heavily product-specific resources here on The Broadcast Knowledge I still believe that knowing AWS is knowing part of the industry.

Here, there are 3 consecutive webinars which cover building a live streaming channel from the fundamentals through to making it operational and ongoing monitoring and maintenance.

Session one at 3pm GMT looks at end-to-end workflows and strategies for redundancy. It looks at both contribution of video into the cloud as much as what happens when it arrives and the delivery.

Session two at 4pm GMT looks examines the more complex workflows where you spread processing/failover across multiple regions and other similar situations.

Session three is the last of the day at 5pm GMT looking at setting up end-to-end monitoring to take the guesswork out of delivering the service on an on-going basis.

Webinar: Deliver global sub-second live streaming experiences to increase viewer engagement

Date: Thursday March 21st, 2019
Time: 15:00 GMT

With live online viewing delayed by up to 30 seconds or more compared to broadcast TV, enriching the viewing experience with online content, while ensuring that all viewers see the action at the same time, is a significant challenge. To provide viewers with engaging online experiences that keep them coming back for more, service providers need true real-time streaming.

This webinar will cover questions such as:

  • How important is latency for live online streaming?
  • Which live streaming workflows offers the greatest opportunity to generate additional revenue?
  • What are the main challenges faced by online video service providers when live-streaming major events such as sports tournaments?

Being a webinar from Limelight, you will also hear

  • How Limelight realtime streaming minimizes latency
  • How to reach the widest audience with native browser support
  • How to enable new business models with interactivity
  • How to reach viewers everywhere

All this along with key findings from DTVE’s industry survey, showing that industry executives believe live streaming could ultimately supplant broadcast technology, but challenges remain.

Video: Encoding efficiencies and techniques

Ed Silvester heads up video R&D at Perform Group, since rebranded to DAZN (pronounced ‘dah zone’) so he’s just the man to talk us through the business aspects of encoding. Anchoring the conversation in the times that black and white TV changed to colour, Ed looks at the challenges DAZN have in creating an innovative platform with backwards compatability.

Ed considers whether the industry should DIET, shedding some older technologies (watch the talk to find out what DIET stands for). And raises some questions about how the industry should deal with platforms ending, scaling and compatibility.

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
