In other words, unless on smart phones, don't expect broadly distributed AV2 encoding hardware.
If it does happen on PC, it will be most likely some courtesy of the hardware chip designers.
Are you sure this isn't just “things I do are commonplace, and things I don't are incredibly niche”?
Video calls is just a feature expected on smart phones, and it means there we better have an hardware encoder.
I don't know if AV2 is defining them, but it needs hard "profiles", that to give a scope for hardware implementations.
Well, it all depends on how AV2 is designed, and defining those profiles is very probably a feedback loop between the AV2 designers and hardware implementors.
(As a side project, I am writting my walyand compositor, and I know that if it supports screen recording, that's going to be something certainly hacky and I can disable at compile time).
I can see a lot of non-techy people not knowing how to do this but among people who know how to do it I bet it’s above 50% who use it
