AOMedia Video 1 (AV1) is an open, royalty-free video coding format initially designed for video transmissions over the Internet. It was developed as a successor to VP9 by the Alliance for Open Media (AOMedia), [2] a consortium founded in 2015 that includes semiconductor firms, video on demand providers, video content producers, software development companies and web browser vendors.
VideoLAN dav1d – An AV1 decoder for decoding videos with AV1 codec; Xiph.Org rav1e – An AV1 encoder written in Rust; Google libgav1 – An AV1 decoder by Google; xvc – An open source video codec, aiming to compete with h.265 and AV1. The reference implementation is released under the LGPL 2.1 and currently available in version 2.0 (as of ...

libvpx is a free software video codec library from Google and the Alliance for Open Media (AOMedia). It serves as the reference software implementation for the VP8 and VP9 video coding formats, and for AV1 a special fork named libaom that was stripped of backwards compatibility.
Some collaboration and work that would later be merged into AV1 predates the official launch of the Alliance. [2]Following the successful standardization of an audio standard in the Internet Engineering Task Force (IETF) in 2012, a working group for the standardization of a royalty-free video format began to form under the lead of members of the Xiph.Org Foundation, [5] who had begun working ...
The quality the codec can achieve is heavily based on the compression format the codec uses. A codec is not a format, and there may be multiple codecs that implement the same compression specification – for example, MPEG-1 codecs typically do not achieve quality/size ratio comparable to codecs that implement the more modern H.264 specification.

The AV1 codec was developed based on a combination of technologies from VP10, Daala (Xiph/Mozilla) and Thor . [ 82 ] [ 83 ] [ 84 ] Accordingly, Google has stated that they will not deploy VP10 internally nor officially release it, making VP9 the last of the VPx-based codecs to be released by Google.
