Video: AV1 Commercial Readiness Panel

With two years of development and deployments under its belt, AV1 is still emerging on to the codec scene. That’s not to say that it’s no in use billions of times a year, but compared to the incumbents, there’s still some distance to go. Known as very slow to encode and computationally impractical, today’s panel is here to say that’s old news and AV1 is now a real-time codec.

Brought together by Jill Boyce with Intel, we hear from Amazon, Facebook, Googles, Amazon, Twitch, Netflix and Tencent in this panel. Intel and Netflix have been collaborating on the SVT-AV1 encoder and decoder framework for two years. The SVT-AV1 encoder’s goal was to be a high-performance and scalable encoder and decoder, using parallelisation to achieve this aim.

Yueshi Shen from Amazon and Twitch is first to present, explaining that for them, AV1 is a key technology in the 5G area. They have put together a 1440p, 120fps games demo which has been enabled by AV1. They feel that this resolution and framerate will be a critical feature for Twitch in the next two years as computer games increasingly extend beyond typical broadcast boundaries. Another key feature is achieving an end-to-end latency of 1.5 seconds which, he says, will partly be achieved using AV1. His company has been working with SOC vendors to accelerate the adoption of AV1 decoders as their proliferation is key to a successful transition to AV1 across the board. Simultaneously, AWS has been adding AV1 capability to MediaConvert and is planning to continue AV1 integration in other turnkey content solutions.

David Ronca from Facebook says that AV1 gives them the opportunity to reduce video egress bandwidth whilst also helping increase quality. For them, SVT-AV1 has brought using AV1 into the practical domain and they are able to run AV1 payloads in production as well as launch a large-scale decoder test across a large set of mobile devices.

Matt Frost represent’s Google Chrome and Android’s point of view on AV1. Early adopters, having been streaming partly using AV1 since 2018 in resolution small and large, they have recently added support in Duo, their Android video-conferencing application. As with all such services, the pandemic has shown how important they can be and how important it is that they can scale. Their move to AV1 streaming has had favourable results which is the start of the return on their investment in the technology.

Google’s involvement with the Alliance for Open Media (AOM), along with the other founding companies, was born out of a belief that in order to achieve the scales needed for video applications, the only sensible future was with cheap-to-deploy codecs, so it made a lot of sense to invest time in the royalty-free AV1.

Andrey Norkin from Netflix explains that they believe AV1 will bring a better experience to their members. Netflix has been using AV1 in streaming since February 2020 on android devices using a software decoder. This has allowed them to get better quality at lower bitrates than VP9 Testing AV1 on other platforms. Intent on only using 10-bit encodes across all devices, Andrey explains that this mode gives the best efficiency. As well as being founding members of AoM, Netflix has also developed AVIF which is an image format based on AV1. According to Andrey, they see better performance than most other formats out there. As AVIF works better with text on pictures than other formats, Netflix are intending to use it in their UI.

Tencent’s Shan Liu explains that they are part of the AoM because video compression is key for most Tencent businesses in their vast empire. Tencent cloud has already launched an AV1 transcoding service and support AV1 in VoD.

The panel discusses low-latency use of AV1, with Dave Ronca explaining that, with the performance improvements of the encoder and decoders along-side the ability to tune the decode speed of AV1 by turning on and off certain tools, real-time AV1 are now possible. Amazon is paying attention to low-end, sub $300 handsets, according to Yueshi, as they believe this will be where the most 5G growth will occur so site recent tests showing decoding AV1 in only 3.5 cores on a mobile SOC as encouraging as it’s standard to have 8 or more. They have now moved to researching battery life.

The panel finishes with a Q&A touching on encoding speed, the VVC and LCEVC codecs, the Sisvel AV1 patent pool, the next ramp-up in deployments and the roadmap for SVT-AV1.

Top Video of 2018: HEVC vs AV1 and the Future of the Codec Battle

 

As the first post of 2019, please allow me to say Happy New Year and to thank you for the time you spend coming to the website, following by email and/or following on social media. Your visits, interest and recommendations are very important and highly appreciated. 2018 ended with being nominated for the Royal Television Society Website of the Year. Whilst the hardworking and knowledgable people at The Broadcast Bridge won, and deservedly so, I hope you’ll be as mighty pleased as I was to see a non-commercial site pitted against the best in the industry. Be assured that The Broadcast Knowledge always aims higher than before so what better motivation than to top that!

As we set our sights on 2019, there’s time for a brief look back at the top video linked to here on The Broadcast Knowledge in 2018. Looking back at the stats, it has the most page visits and the most clicks, so let’s revisit this panel on AV1 and HEVC. It’s not often you get the likes of Facebook and Harmonic sharing their latest research on stage with companies like Harmonic and Bitmovin who are very active in the Codec community, so it’s no surprise this piqued the interest of many.

This panel took place during NAB 2018 when AV1 had just ‘released’ the AV1 codec at the show but the points discussed are as relevant today as they were then including the adoption of HEVC in the marketplace. Having said that, do check out the AV1 and HEVC tags to see what more recent discussions there have been including a discussion of the future of video codecs at Streaming Media East 2018

Sit back and watch HEVC vs AV1 and the Future of the Codec Battle!

Video: High Dynamic Range in AV1

Google and University of Warwick explain AV1, its current status and how its can support HDR with WMG’s trueDR at the IABM’s Future Trends Theatre at IBC 2018.

Matt Frost from Chrome Media takes the stage first giving an overview of AV1’s goals, objective quality tests and where we are in AV1’s timeline as well as answering many questions from the audience.

Next Alan Chalmers from University of Warwick explains how they added HLG, HDR10 (PQ) to AV1. Also added are new, scene-referenced, HDR methods which Alan explains the works of and reasons for.

Video: HEVC Vs AV1 and the Future of the Codec Battle

In this debate from NAB 2018, the panel discusses the video codecs which are competing to be the next-generation standard in the OTT environment and, notably, HEVC and AV1 being the front-runners. The debate on which video standard is best suited to our industry is in full swing especially as the Alliance for Open Media released AV1 at the NAB Show and Apple is supporting HEVC in its products and has decided to join the Alliance for Open Media as a founding member. This panel discusses the pros and cons of HEVC and AV1, and also put in perspective content-aware encoding techniques with AVC that might be a strong challenger in the short term for OTT distribution.
