"Set for a year-end release, AV2 is not only an upgrade to the widely adopted AV1 but also a foundational piece of AOMedia’s future tech stack.
AV2, a generation leap in open video coding and the answer to the world’s growing streaming demands, delivers significantly better compression performance than AV1. 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. AV2 marks a milestone on the path to an open, innovative future of media experiences."

I’ve always wondered why there isn’t VR optimized compression. Seems like each eye would mostly have similar or shifted pixels than the other. Nice to see some work being done in this space
I’d be interested in more partial acceleration/offloading support.
As an example, the denoising AV1 does for grain synthesis is hard, but GPUs are really good at it. It would be awesome if they could offload that step to vulkan as an option.
Another would be better supported variable frame rate. But that’s a tall ask I guess.
Great, and I just bought a new GPU. Wonder if I’ll get HW coding support for my 9070 XT, or maybe at least my 9950X3D… 🙏
Don’t sweat it. By the time AV2 starts getting serious adoption rolled out, your hardware will be 5+ years old
I’m hoping it will be faster than that, but yeah probably.
I put the base at 5 years being optimistic. I’m not expecting 5 years from final spec publishing. A stable spec is released end of the year so pretty much 2026. Take a couple years for hardware decoders to start releasing in niche to expensive gear. Pretty much demonstrative gear.
Then progressively decoders proliferate down to consumer gear with years to get down to cheap entry level gear. Keep in mind the Snapdragon 7 Gen 4 this year was the first 7 series chip to get an AV1 hardware decoder. Don’t know about Snapdragon 6 and 4 series of chips. AV1 stable spec was like 2018
Maybe AV2 adoption will be quicker because VVC seems to have garnered minimal interest since 2020. However long it takes, you’ll be itching for a new computer by then. Lessons learned from what adoption took for AV1 for AV2 development. Regardless, content distribution will trail hardware decode adoption on mass media devices, phones - maybe even have to wait for people to replace their televisions with ones that have AV2 decoders in them
Wonder if I’ll get HW coding.
It will not :(
It basically always fixed function, eg they would literally have to etch it into the silicon. If it’s not already there, you ain’t getting it.
The Xbox One did get a GPU shader decoder, IIRC. But that was an absolute crack project built out of necessity and a lot of financial interest (as its CPU was really bad).
