They've been working with Intel on AV1 hardware since 2019.

Unfortunately AV1 hardware acceleration support was really slow. Apple only just adopted it in their new SoCs. Qualcomm didn't support it until recently either. It's probably still years till the hardware support is anywhere close to H.265, or even H.264 (the currently most common format). It's possible to decode AV1 in software, but the computation requirements are quite high.

HEVC is from the VP9 generation of codecs. Qualcomm has supported VP9 decoding since 2016 (Snapdragon 820). Unfortunately, no Apple device has ever supported hardware accelerated VP9 decode, so HEVC is the only UHD option on those devices.

I guess it doesn't really matter anyway since AV1 is also patent encumbered...

For netflix? its not that simple. Video codec design is a mammoth task. Sure you can make your own fairly easily, but making an efficient, hardware accelerated encoder that is suitable for broadcast work is one thing.

Making a spec for consumer hardware to implement, efficiently and cheaply is another.

go and read the spec for MPEG2, then compare it to MPEG 4, with all the amendments to make h.264. Its a lot of work.

Probably is a good thing that they've already been on the case [for 5+ years](https://en.wikipedia.org/wiki/AV1) then.

I do realize this, I didn't mean literally yesterday as in "the day before today", but more "earlier in time".
