4/21/2023 0 Comments Av1 ffmpeg![]() To date, AOM has published five specifications, for the AV1 Bitstream, AV1 in ISOBMFF, ID3 Timed Metadata, AV1 Image File format, and RTP payload Format for AV1 (draft). However, mobile hardware deployments appear to be pushed out to 2026-2027 (see David Ronca’s interview with John Porterfield here, about 31 minutes in), changing the mobile strategy from hardware support to software support. AV1 support within Chrome, Edge, and Firefox came very quickly, and the first Smart TVs with AV1 support shipped in early 2020 as predicted. At the time, AOM members predicted prompt support within most member company’s browsers, and a two-year adoption cycle for mobile and OTT applications. In addition, three of the founding companies were separately working towards an open-source codec - Google (VP10), Cisco (Thor), and Mozilla (Daala) - so it made sense to join forces and produce a single open-source code.ĪV1 was finalized and launched around May 2018. The group formed because member companies like Google were frustrated that they didn’t have relevant input into standards-based codecs, and because many in the founding group were concerned about confusing and overreaching HEVC royalty policies. The AV1 codec is the first codec shipped by the Alliance for Open Media (AOM), a consortium of streaming companies anchored by founding members like Amazon, Apple, Cisco, Facebook, Google, Intel, Microsoft, Mozilla, Netflix, NVIDIA, and Samsung. As you’ll read, even YouTube only uses the AV1 codec on videos that are watched several millions of times.Īt the time of this writing, AV1 isn’t supported in any of Wowza’s products or services. Encoding cost and the codec’s limited but growing reach also narrow the relevant scope of video on demand (VOD) applications. As you will learn, the AV1 codec is challenging to transcode in real time at this point in time, so it doesn’t play a role in many live workflows, excepting some WebRTC implementations. This article provides a quick overview of the AV1 codec: what it is, how it performs, what it costs, and what it’s good for.
