The mystery is who is paying whom ? Is Microsoft paying for HEVC licences ? Google ? Distributor ? Silicon vendors ? All of them ? The question above is, "Why use HEVC(pay) when AV1 exists ?". Or, "Why care about AV1 if everyone is paying ?"
>Because HEVC has hardware support, right now, so it's faster.
Most new hardware supports hardware decode for AV1 too. There were 1-2 generations prior to the current one that had HECV but not AV1, but that sample size will become irrelevant over time.
>People don't much.
Well, clearly people who make decisions do. If you ask an average person on the street if they care about HEVC or AV1, they don't. If you ask Netflix or Google, they do.
"Netflix has also partnered with YouTube to develop an open-source solution for an AV1 decoder on game consoles that utilizes the additional power of GPUs."
But still today you can take an HEVC iPhone or GoPro video and watch it on your PS5 with full hardware encoding. This open source solution doesn't help with that.
To play HEVC files.
> when AV1 exists?
In case your files aren't AV1, or in case you don't have the hardware to play AV1.
Not a mystery is it?
