“Look for AV1 to have meaningful market share in 2021 or 2022. With much of VP10's technology being incorporated into AV1, some think of VP9 as "AV0." ![]() Every Android phone and Chrome browser offers support for VP9. VP9, developed by Google, is enabled in billions of devices. Why would I spend 10 times as much to encode AV1 when I get maybe 20 or 25 percent gain in compression efficiency?” VP9 Some people say that in a few years it will only be 5-10 times more complex. Today, it you try to encode an AV1 stream, it’s 100 times slower than encoding to HEVC in software. "The second thing about AV1 is encode performance. And hardware decode isn’t expected until 2020," says Dror Gill, Beamr's chief technology officer. Software playback just won’t work - it would drain the battery. “For AV1, you need hardware decoding in the. It is still early days for AV1, and while many companies at IBC are developing AV1 codecs and are bullish on AV1’s potential, the codec’s slow performance to date has dampened enthusiasm. AV1ĪV1 is a codec developed by the Alliance for Open Media in part to alleviate the royalty problem faced by HEVC. For many companies, it's not that HEVC royalties are too high. However, lingering uncertainty about future royalties for HEVC has limited adoption and has precluded some companies from using the codec at all. HEVC (or a similarly efficient codec) is also required to generate reasonably sized 4K and 8K UHD (Ultra High Definition) files. Thus, the deployment of HEVC is largely driven by potentially significant savings on bandwidth and infrastructure costs. HEVC can achieve the same QoE with smaller files, which cost less to deliver and store. HEVC/H.265Īccording to the 2018 Bitmovin format report, and anecdotally at the IBC, HEVC (High Efficiency Video Codec), or H.265 accounts for less than 10 percent of encoded files. Today, almost all encoding companies generate the majority of their encoded output as H.264 ABR files. AVC/H.264Īdaptive bitrate encoding (ABR), through which encoders generate a "ladder" of resolutions at various bitrates from which device decoders "choose" the bitrate that delivers the optimal QoE, has become a standard in our multiscreen world. Before we examine how some vendors are addressing those challenges, here’s a quick refresher on the technologies that define encoding, transcoding, packaging, and delivery in late 2018. While the streaming landscape has changed in dramatic ways, some current challenges, such as codec uncertainty, look familiar. Video content in emerging markets with 2G or 3G networks.8K UHD programming in Japan and elsewhere.eSports events drawing millions of viewers. ![]() Vast VOD offerings from Netflix, Amazon Prime, Hulu, and other providers.Sports, music, and other events drawing massive audiences.The proliferation of 24/7 linear channels.These teams are being challenged to support a growing variety of streaming video use cases, including: Today, we can do two HEVC encodes of Ultra HD on an off-the-shelf, non-accelerated pure CPU." Morten Rasmussen, Cisco senior product manager for video compression, cites an example: "A few years ago, we were not able to do even one Ultra HD encode of HEVC on a single server. Video engineering teams continue to improve the consumer's quality of experience (QoE) while minimizing required resources. ![]() ![]() Advertisers are following the trend, too Magna’s US Ad Spend Forecast, estimates OTT annual ad spend will grow 40% this year to reach $2 billion by the end of 2018.īuffering-related video freezes have become increasingly rare, and talk at this year’s IBC in September was of more nuanced challenges, like how to reduce latency or how to use per-title or content-aware encoding (CAE) to minimize bitrates, thus saving millions of dollars in bandwidth and infrastructure costs. With billions of HD video, streaming-enabled devices in the hands and homes of consumers, and high-speed broadband a fact of life in most parts of the world, over-the-top (OTT) video streaming is now understood-even by traditional over-the-air broadcasters-as the path to the video future. The key takeaway from this year's International Broadcasting Convention (IBC) in Amsterdam was that the flood of streaming video is finally flowing. The tiny, jerky videos that we see on websites today will soon become a flood of full-frame, full-motion video integrated into many, if not most, corporate and entertainment websites…”- Streaming Media Magazine, August 2000 "Great floods begin with the pitter-patter of tiny raindrops, and so it is with video on the web.
