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.
While SVT-AV1 already performs very well in constrained quality mode and is economically usable for many scenarios, as of the time being commercial implementations like Aurora1 may still beat it.

Initial VCE support was added on 4 February 2014 by Christian König of AMD to the free radeon driver. [50] Gallium3D state tracker for OpenMAX was added 24 October 2013 to Mesa 3D. [51] The free and open-source Radeon driver was adapted to use OpenMAX with the GStreamer OpenMAX (gst-omx) support for exposing the VCE video encode engine. [52]
After version 10.0.0, 64-bit codecs are integrated into the regular editions. Prior to this version there was a 64-bit edition designed specifically for 64-bit OSes. After version 11.3.0, the 32-bit and 64-bit versions of LAV Filters share their settings, and an option to install only 64-bit codecs was added (visible only in Expert install mode).
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.

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 ...
libvpx was released as free software by Google on May 19, 2010, after the acquisition of On2 Technologies for an estimate of over 120 million US dollars. [2] [4] In June 2010, Google amended the VP8 codec software license to the 3-clause BSD license [5] [6] [7] after some contention over whether the original license was actually open source. [8 ...
