Netflix and Intel to Deploy AV1 CODEC For Content Streaming
At The National Association of Broadcasters Show today, Intel and Netflix announced a new high-performance video codec that is available as open source and royalty-free to content creators, developers and service providers. Scalable Video Technology for AV1 (SVT-AV1) offers performance and scalability in video processing.
AV1 is a royalty-free codec and offers improved compression compared to vp9 or hevc, the video bandwidth reduction can run upwards to 30 to 40 percent, without you seeing a difference. The best thing yet, this is a royalty-free model.
Modernization of video software codecs for increased efficiency will help deliver rich user experiences and reach global scale, accelerating time to market and lowering costs for developers and service providers. SVT-AV1 is a software-based scalable codec offering the best trade-offs among performance, latency and visual quality when working with visual cloud workloads. SVT-AV1 performance advantages are based on the SVT architecture, which is a cohesive and highly optimized codec architecture that already has delivered multiple generations of codecs, including SVT-HEVC, SVT-VP9 and SVT-AV1. The new SVT-AV1 codec is unique in that it allows encoders to scale their performance levels based on the quality and latency requirements of the target applications — ranging from highest quality video on demand (VOD) to livestreaming use cases. The high-quality encoding and decoding in SVT-AV1 will enable developers working with visual cloud workloads to get them to market faster. The codec is optimized for video encoding on Intel Xeon Scalable processors.
What Netflix Says: “The SVT-AV1 collaboration with Intel brings an alternative AV1 solution to the open-source community, enabling more rapid AV1 algorithm development and spurring innovation for next-generation video-compression technology,” said David Ronca, director of Encoding Technologies, Netflix.
Even More News: In addition, Intel launched the Open Visual Cloud, an open-source project that includes a set of use case-optimized reference pipelines for visual workloads. These developer-ready pipelines are based on open-source media, artificial intelligence (AI) and graphics software ingredients. They support the most popular open-source frameworks that developers are familiar with. SVT, the OpenVINO™ Toolkit and the Intel® Rendering Framework are all part of the Open Visual Cloud, bringing highly optimized open source encode/decode, inference and graphics together as an interoperable reference for services innovation. The first two pipelines enable services for content delivery network (CDN) transcode VOD streaming and intelligent ad insertion.
Intel will demonstrate cloud graphics and immersive media pipelines in development at NAB. Additional reference pipelines will be released on a quarterly basis.
How You Access It: The SVT-AV1 codec is available under a permissive BSD+Patent license, which will make it easy to adopt and commercialize. Developers can access SVT-AV1 at 01.org/OpenVisualCloud/svt. The Open Visual Cloud reference pipelines and building blocks for encode/decode, inference and render can be found on 01.org/OpenVisualCloud.

Well this didn't say anything... what bitrates and resolutions? what about HDR? which processors will support it?
just an empty announcement

prior to multithreading and asm level optimsiations, the sample decoder DID destroy low power processors.
Considering how powerful even a mid range mobile phone's CPU is these days, that's not going to be an issue.

MPC-HC lastest build supports AV1 SW decoding. On my 5960X@4.4Ghz all 16 threads are used and 4K videos are not totally smooth for now.
MPC may require some additional optimizations but without an HW decoder most of the CPU won't be able to decode it.
thank you for demonstrating that the previous few users have no idea about decoding video.

What decoder MPC-HC uses?
Blue is normalized Reference decoder. Then you see improvement on each platform.
It does not necessarily mean that It is faster on Zen.
it means that dav1d decoder provides much higher boost in performance on Zen platform in comparison to reference than it does on haswell.
Either way, use of better decoder provides 3 times the performance on intel and 4 times for AMD in comparison to just using reference.
Those decoders are new and clearly far from optimized.
