AV1 is Well On Its Way To Becoming a Viable Alternative To Patented Video Codecs, Mozilla Says

An Invisible Tax on the Web: Video Codecs

 

 

Here’s a surprising fact: It costs money to watch video online, even on free sites like YouTube. That’s because about 4 in 5 videos on the web today rely on a patented technology called the H.264 video codec.

 

A codec is a piece of software that lets engineers shrink large media files and transmit them quickly over the internet. In browsers, codecs decode video files so we can play them on our phones, tablets, computers, and TVs. As web users, we take this performance for granted. But the truth is, companies pay millions of dollars in licensing fees to bring us free video.

 

It took years for companies to put this complex, global set of legal and business agreements in place, so H.264 web video works everywhere. Now, as the industry shifts to using more efficient video codecs, those businesses are picking and choosing which next-generation technologies they will support. The fragmentation in the market is raising concerns about whether our favorite web past-time, watching videos, will continue to be accessible and affordable to all.

A drive to create royalty-free codecs

Mozilla is driven by a mission to make the web platform more capable, safe, and performant for all users. With that in mind, the company has been supporting work at the Xiph.org Foundation to create royalty-free codecs that anyone can use to compress and decode media files in hardware, software, and web pages.

 

But when it comes to video codecs, Xiph.org Foundation isn’t the only game in town.

 

Over the last decade, several companies started building viable alternatives to patented video codecs. Mozilla worked on the Daala Project, Google released VP9, and Cisco created Thor for low-complexity videoconferencing. All these efforts had the same goal: to create a next-generation video compression technology that would make sharing high-quality video over the internet faster, more reliable, and less expensive.

 

In 2015, Mozilla, Google, Cisco, and others joined with Amazon and Netflix and hardware vendors AMD, ARM, Intel, and NVIDIA to form AOMedia. As AOMedia grew, efforts to create an open video format coalesced around a new codec: AV1. AV1 is based largely on Google’s VP9 code and incorporates tools and technologies from Daala, Thor, and VP10.

Why Mozilla loves AV1

Mozilla loves AV1 for two reasons: AV1 is royalty-free, so anyone can use it free of charge. Software companies can use it to build video streaming into their applications. Web developers can build their own video players for their sites. It can open up business opportunities, and remove barriers to entry for entrepreneurs, artists, and regular people. Most importantly, a royalty-free codec can help keep high-quality video affordable for everyone.

The second reason we love AV1 is that it delivers better compression technology than even high-efficiency codecs – about 30% better, according to a Moscow State University study. For companies, that translates to smaller video files that are faster and cheaper to transmit and take up less storage space in their data centers. For the rest of us, we’ll have access to gorgeous, high-definition video through the sites and services we already know and love.

 

Open source, all the way down

AV1 is well on its way to becoming a viable alternative to patented video codecs. As of June 2018, the AV1 1.0 specification is stable and available for public use on a royalty-free basis. AV1 is the strongest candidate to meet the criteria of the Internet Engineering Task Force (IETF), which seeks to create standards for next-generation, royalty-free video formats for the internet. With the IETF’s support, it may be possible to update the WebRTC standard to list AV1 as the “Mandatory to Implement” codec, which will further encourage broad interoperability.

 

The AV1 project is driven by the NETVC Working Group, whose primary contributors include Netflix, Huawei, Mozilla, Cisco, and others. Technically-minded folks can tune in to the NETVC meeting minutes for news about this promising contender. Looking for a deep dive into the specific technologies that made the leap from Daala to AV1?

No one mentioned it's released already. Why no one has covered this enough.

 

Anyway, get ready to buy new hardware to support this. Everyone knows how much CPU power H.265 uses and how much hardware support it has. This says it has a small footprint but I want to see the tests for it.

 

The good thing is a lot of hardware manufacturers are onboard with this, from desktop hardware manufacturers to mobile ones.

 

I wonder when will Firefox release it in the full version though.

H265 is not very bad if its used   to compress videos down small  it don't hurt desktops to use a little CPU  i have lots of videos  in h265 8bit and 10bit  , 10bit and 12bit uses more cpu than you're basic 8 bit. But 10 bit has a better picture ... Now streaming h265 is a different story on low end pc you can stream H265 pretty good using  Linux with  but windows only have the 32 bit Kodi that's stable and the videos and stuff wont pay very good streaming but as far as playback using some x64 players local it fine on windows . But with cheap   TV Boxes with Android Linux  and  LibreELEC  Linux for older TV boxes that cant be upgraded to the latest Android you can stream full 30 or 40 GB  4k H265 UHD BLU-Ray Disc   , H265  is no were on the web other than on pirate sites  its used for Disc  . To play 4k h265 on Windows you need  expensive hardware so its not even worth it. The tech is there now it just much cheaper to use a TV Box To do .

 AV1 ASICs will be ready in a year after bitstream freeze. A year after that we'll see HW decode in products.

AV1 will replace the already widely used VP9. I dont think AV1 will replace h265 on the BD UHD, but maybe the next generation disks.

It's a new video codec, It's the most efficient in the world (and the slowest right now). Specs are finalized, this means browsers, players and hardware decoders can now implement it and you will be able to play AV1 content soon.

It's oriented for HD content on the web, so probably Youtube will be the first to serve it when the browser will include a good enough implementation.

If AV1 implementations are getting faster, we probably see it in the pirate scene too.

 

 

Soon they will be hardware decoders in players for AV1 were we will able to play it at lower bitrates with older hardware on low end PCs even . You will be able to brute force it it too play bigger videos a mid range to high end PCS on older hardware as well.   .
