Video: Running live video with FFmpeg

Posted on 26th March 2019 by Russell Trafford-Jones

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

Posted on 22nd March 2019 by Russell Trafford-Jones

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.

To mark International Women’s Day, Eyevinn Technology have opened their premium archives to allow you to watch two videos for free until 11th March which are normally reserved for patrons of the Streaming Tech Sweden conference – so act quickly to watch Netflix’s Megha Manohara discuss Netflix’s dynamic optimiser framework and how they ensure best quality over a variety of bandwidths.

Megha covers encoding testing, metrics such as VMAF, visualising the results, per-shot encoding and the way they validate with their audience they have done a good job.

Streaming Tech Sweden is an annual conference which prides itself on excellence and independence. Without sponsors, they are free to pick the best and the most relevant speakers working on at the cutting edge of video streaming. The talks from Streaming Tech Sweden 17 are free to watch, but those from 2018 are available for attendees only. Later in 2019, they will become free, but until then, this is a short opportunity to watch these two great talks in order to mark International Women’s Day 2019. Registration with the site is free.

The second talk available from Streaming Tech Sweden 2018 is from Codemill’s Johana Björklund talking about contextual marketing and ad personalisation. Johana explains how the ads work, how GDPR has changed the way personalisation is carried out and how video metadata is used to find pre-roll and post-roll ads.

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

Posted on 5th March 2019 by Russell Trafford-Jones

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.
