AOMedia AV2 video codec draft specification release, and a quick try at the reference implementation

After 5 years of work and over 2700 commits against the reference software, the Alliance for Open Media (AOMedia) has recently released the AV2 specification. This next-generation open video codec provides up to 40% bandwidth reduction over AV1 at equivalent quality. The document entitled "AV2 Bitstream & Decoding Process Specification" specifies the Alliance for Open Media Video 2 (AV2) bitstream syntax, semantics, parsing process, and decoding process. AV2 builds upon the foundation of AV1 and has been engineered to provide higher compression efficiency and high-quality video delivery at lower bitrates. The Alliance for Open Media also highlights that it provides better "support for AR/VR applications, split-screen delivery of multiple programs, improved handling of screen content, and an ability to operate over a wider visual quality range". The AOMedia Video Model (AVM) serves as the official reference software, and tools and source code can be found on GitLab. Note that reference

The Alliance for Open Media (AOMedia) will release the AV2 open video codec specification by the end of the year, as an update of the now widely-used AV1 video codec with up to 40% bandwidth reduction at the same level of quality. In the meantime, Debargha Mukherjee, Google Principal Engineer, has shared a progress report about AV2, first offering a historical perspective with the list of digital video codecs from 1990 to 2030 (expected), then stating AV2 goals, and going through requirements, coding tools, and what's been achieved so far. You can check the eleven-minute presentation (04:27 - 15:30) embedded at the end of this post, or continue reading for the highlights of the talk. AV2 will be released very soon, while the H.267 proprietary video codec might only be released around 2030. We haven't seen a lot of support/traction for H.266, so we'll have to see if H.267 ever
