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.
Some are combinations of common container formats and audio and video coding profiles, such as AVCHD and DivX formats. Although sometimes compared to DivX products, Xvid is neither a container format nor a video format, it is a software library that encodes video using specific coding profiles of the common MPEG-4 ASP video format. Those types ...
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 ...
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 eleventh generation of PureVideo HD, introduced with the Ampere-based GeForce RTX 30 series with fifth generation NVDEC, introduces 8K@60 hardware-decoding capability for AV1 Main profile (4:0:0 and 4:2:0 chroma subsampling with 8 or 10-bit depth) with resolution of up to 8192 x 8192 pixels to the GPU's video-engine.

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 ...
