Netflix announced this week that it has started to stream titles in AV1 on Android in what could significantly help the two-year-old media codec gain wider adoption.
The world’s biggest streaming giant said on Wednesday that by switching from Google’s VP9 — which it previously used on Android — to AV1, its compression efficiency has gone up by 20%.
At the moment, only “select titles” are available to stream in AV1 for subscribers “who wish to reduce their cellular data usage by enabling the ‘Save Data’ feature,” the American firm said.
Netflix hasn’t shared much about the benefit AV1 will provide to customers, but the new media codec’s acceptance nonetheless sends a message by itself.
Tech giants, including Google, have spent years developing and improving media codecs as consumption of data skyrocketed and low-cost devices began to sell like hotcakes. But they just can’t seem to settle on one media codec and universally support it.
Think of Safari and YouTube, for instance. You can’t stream YouTube videos in 4K resolution on Safari, because Apple’s browser does not support Google’s VP9. And Google does not support HEVC for 4K videos on YouTube.
AV1 is supposed to be the savior media codec that gets universal support. It’s royalty-free and it works atop of open-source dav1d decoder that has been built by VideoLAN, best known for its widely popular media player VLC and FFmpeg communities. It is sponsored by the Alliance for Open Media.
Who are the members of Alliance for Open Media? Nearly all the big guys: Apple, Google, Amazon, Netflix, Nvidia, ARM, Facebook, Microsoft, Mozilla, Samsung and Tencent, among others.
But that’s not to say there aren’t roadblocks in the adoption of AV1. Compared to HEVC — the format that AV1 is supposed to replace in popularity — encoding in AV1 was noticeably slower a year ago, as per some benchmark tests.
Adoption of AV1 by various browsers, according to analytics firm StatCounter. Safari is yet to support it.
Netflix’s announcement suggests that things have improved. The streaming giant said its goal is to support AV1 on all of its platforms. “In the spirit of making AV1 widely available, we are sponsoring an open-source effort to optimize 10-bit performance further and make these gains available to all,” it said in a blog post.

This Week in Apps: Apple antitrust issues come to Congress, subscription apps boom, Tencent takes on TikTok
Welcome back to ThisWeek in Apps, the Extra Crunch series that recaps the latest OS news, the applications they support and the money that flows through it all.
The app industry is as hot as ever with a record 204 billion downloads in 2019 and $120 billion in consumer spending in 2019, according to App Annie’s recently released “State of Mobile” annual report. People are now spending 3 hours and 40 minutes per day using apps, rivaling TV. Apps aren’t just a way to pass idle hours — they’re a big business. In 2019, mobile-first companies had a combined $544 billion valuation, 6.5x higher than those without a mobile focus.
In this Extra Crunch series, we help you keep up with the latest news from the world of apps, delivered on a weekly basis.
This week, there was a ton of app news. We’re digging into the latest with Apple’s antitrust issues, Tencent’s plan to leverage WeChat to fend off the TikTok threat, AppsFlyer’s massive new round, the booming subscription economy, Disney’s mobile game studio sale, Pokémon GO’s boost to tourism, Match Group’s latest investment and much more. And did you see the app that lets you use your phone from within a paper envelope? Or the new AR social network? It’s Weird App Week, apparently.

Apple buys edge-based AI startup Xnor.ai for a reported $200M
Xnor.ai, spun off in 2017 from the nonprofit Allen Institute for AI (AI2), has been acquired by Apple for about $200 million. A source close to the company corroborated a report this morning from GeekWire to that effect.
Apple confirmed the reports with its standard statement for this sort of quiet acquisition: “Apple buys smaller technology companies from time to time and we generally do not discuss our purpose or plans.” (I’ve asked for clarification just in case.)
Xnor.ai began as a process for making machine learning algorithms highly efficient — so efficient that they could run on even the lowest tier of hardware out there, things like embedded electronics in security cameras that use only a modicum of power. Yet using Xnor’s algorithms they could accomplish tasks like object recognition, which in other circumstances might require a powerful processor or connection to the cloud.
Xnor’s saltine-sized, solar-powered AI hardware redefines the edge
CEO Ali Farhadi and his founding team put the company together at AI2 and spun it out just before the organization formally launched its incubator program. It raised $2.7M in early 2017 and $12M in 2018, both rounds led by Seattle’s Madrona Venture Group, and has steadily grown its local operations and areas of business.
The $200M acquisition price is only approximate, the source indicated, but even if the final number were less by half that would be a big return for Madrona and other investors.
The company will likely move to Apple’s Seattle offices; GeekWire, visiting the Xnor.ai offices (in inclement weather, no less), reported that a move was clearly underway. AI2 confirmed that Farhadi is no longer working there, but he will retain his faculty position at the University of Washington.
An acquisition by Apple makes perfect sense when one thinks of how that company has been directing its efforts towards edge computing. With a chip dedicated to executing machine learning workflows in a variety of situations, Apple clearly intends for its devices to operate independent of the cloud for such tasks as facial recognition, natural language processing, and augmented reality. It’s as much for performance as privacy purposes.
Its camera software especially makes extensive use of machine learning algorithms for both capturing and processing images, a compute-heavy task that could potentially be made much lighter with the inclusion of Xnor’s economizing techniques. The future of photography is code, after all — so the more of it you can execute, and the less time and power it takes to do so, the better.

It could also indicate new forays in the smart home, toward which with HomePod Apple has made some tentative steps. But Xnor’s technology is highly adaptable and as such rather difficult to predict as far as what it enables for such a vast company as Apple.

Have we hit peak smartphone?
Last Halloween, we broke down some “good news” from a Canalys report: the smartphone industry saw one-percent year-over-year growth — not exactly the sort of thing that sparks strong consumer confidence.
In short, 2019 sucked for smartphones, as did the year before. After what was nearly an ascendant decade, sales petered off globally with few exceptions. Honestly, there’s no need to cherrypick this stuff; the numbers this year have been lackluster at best for a majority of companies in a majority of markets.
For just the most recent example, let’s turn to a report from Gartner that dropped late last month. The numbers focus specifically on the third quarter, but they’re pretty indicative of what we’ve been seeing from the industry of late, with a 0.4 percent drop in sales. It’s a fairly consistent story, quarter after quarter for a couple of years now.
