概述

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), a consortium founded in 2015 that includes semiconductor firms, video on demand providers, video content producers, software development companies and web browser vendors.

现状

  • Netflix and yutube already support AV1

  • 相比 H264, VP9, H265, AV1 在相同码率下 VMAF 和 MOS 值都是最高的,也是就质量最高
