AV2 is the next-generation video coding specification from the Alliance for Open Media (AOMedia). Building on the foundation of AV1, AV2 is engineered to provide superior compression efficiency, enabling high-quality video delivery at significantly lower bitrates. It is optimized for the evolving demands of streaming, broadcasting, and real-time video conferencing.
This specification serves as the definitive technical reference for AV2 implementations. It outlines the bitstream syntax, semantics, and decoding processes required to ensure full conformance.
AV2 provides enhanced 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.

Considering how long AV1 adoption has taken, you probably have a decade before you need to worry about needing AV2 support.

A large FPGA could work as a hardware video decoder that is software updatable. Unfortunately they are way to expensive for consumer hardware.
It would be nice if someone would make low cost hardware video decoders on an m.2 module. Then it could be easily upgraded even on a laptop.
