The AV2 Video Standard Has Released (Final v1.0 Specification)
AV2 video codec specification reaches final v1.0 release from the Alliance for Open Media.
The Alliance for Open Media has released the final v1.0 specification for AV2, the next-generation video coding standard building on AV1. AV2 offers improved compression efficiency for streaming, broadcasting, and video conferencing. It adds support for augmented/virtual reality applications, multi-stream delivery, enhanced screen content handling, and wider visual quality range support. The specification includes syntax definitions, decoding processes, a reference software implementation (AVM v1.0.0), and multiple formats: a complete specification document, PDF version, C header lookup tables, and a syntax browser with search and navigation features.
Implementers can access the full specification online or offline, review syntax and semantics side-by-side, and reference the official AVM software from AOMedia's GitHub repository at the v1.0.0 tag.
What HN community is saying
Commenters emphasize that spec finalization is one early step in a long adoption path. The reference encoder currently runs around 1fps and remains impractical; hardware acceleration is expected around 2028 with mainstream adoption unlikely before 2030. The codec offers 20-30% efficiency gains over AV1 and multi-stream support for VR and live sports, but efficiency alone does not justify adoption yet. Debate emerged on hardware encoder necessity: desktop/content distribution needs software encoding fine, but real-time applications like video calls and camera recording require hardware acceleration. One commenter noted AV1 software encoding works adequately even on mobile for low bitrate calls. Separately, Dolby's patent litigation against Snapchat over AV1 remains unresolved with no recent updates.
