And whilst AV1 and H.265 are pretty close in PSNR where it is inferior is in vendor support. There are TVs for example available today that natively support H.265 whereas AV1 is still in development. Not to mention all of the terrestrial broadcast providers all using H.265.
> the link you posted is using x265 which as the article suggests was ranked 4th out the 6 available encoders
The other encoders there are commercial or not publicly available as far as I can tell, so it's hard to use them as a comparison. Plus according to that PDF, the best encoder is 0.85x x265, which is about the same as AV1 in its present state in the video I linked. And again, AV1 isn't even finalized yet, so I actually find it somewhat impressive that it can already compete against these highly tuned encoders with years of development put into them.
> where it is inferior is in vendor support
Of course there's no vendor support now, the codec isn't even finalized yet. However the codec is backed by Microsoft, Google, Mozilla, Qualcomm, Intel, AMD, ARM, Broadcom, NVIDIA, Adobe, Netflix and the BBC, i.e. all but 1 of the major browser and OS vendors, every major mobile, server and desktop processor company and the 2 most widely used video streaming companies.
H.265 is already in shipping hardware from Sony, LG, Samsung, Intel, AMD, ARM, Nvidia etc. As I listed above there are at least 100+ more companies supporting H.265 than AoM. Including the most important of all the broadcast standard for terrestrial TV which is still hugely popular in many countries.
Also without Apple it's over. YouTube and Netflix will be forced to support H.265 or give up on iOS/OSX users (350 million users).

AV1 isn't finalized yet. Of course HEVC is being shipped in more stuff, it's being shipped at all. I'm not debating this, there's no debate. At present HEVC has more support than a codec that isn't yet finished. H.264 had more support when VP9 was being developed too, that doesn't make VP9 inferior to H.264.
> broadcast standard for terrestrial TV which is still hugely popular in many countries
Broadcast TV is a different world to the web and has very different concerns.
> Also without Apple it's over. YouTube and Netflix will be forced to support H.265 or give up on iOS/OSX users (350 million users).
This is demonstrably not true as YouTube and Netflix both currently and successfully utilize VP9, which Apple doesn't support. Apple users just get the inferior H.264 codec.
The question is really whether the browser and other OS vendors are going to start supporting HEVC and given the current patent situation, that seems impossible, so we're going to end up in a fragmented world where for web streaming, most users get AV1 while Apple users and anyone else who doesn't support AV1 gets H.264.
Is that a criticism of the format's potential? No! But it may as well not exist until it is finalized... so it can't be a competitor to a format that has been.
> VP9 and AV1 are simply inferior codecs to H.265 in almost every way.
This was your claim.
Let me sum up the entirety of my position so we're on the same page:
- In terms of compression, AV1 is competitive with or beats HEVC, despite not being finalized.
- AV1 has support from everyone but of import save Apple when it comes to the web.
- Apple's support is not necessary for a codec to be successful (see VP9).
- AV1 is not finalized. There's more work to do. Particularly, I don't expect the present encoder/decoder implementations to be competitive with the HEVC encoders when it comes to CPU efficiency.
- HEVC has solid adoption in some areas (the more "traditional" areas like video cameras, TVs, broadcast) but has zero adoption when it comes to the web and this is extremely unlikely to change due to the patent mess.
- As members of the AoM, it's near certain that Microsoft, Google and Mozilla will add AV1 support to their browsers, which, depending on the particular source you look at, cover roughly 70% of the total browser market.
- Due to AoM support and HEVC not being an option, AV1 will be the primary successor to H.264/VP9 on the web.
- Due to its likely widespread availability from streaming services on the web and support from hardware vendors, AV1 will be prolific in other kinds of hardware.
- Due to the support of Apple and the broadcast industry, HEVC will likely not go away anytime soon.
- I agree that HEVC is not currently a viable alternative to HEVC, it not being finalized yet and all, however despite that, there are already aspects in which it is already superior, namely compression and likelihood of being supported on the web.
> The video codec AV1 currently in development was supposed to be a grand alliance of disparate companies to agree on a common format for the future, and rectify the WebM vs. non-WebM split, but continuing to promulgate sophisticated formats based on work outside of this scope (such as MPEG- or ITU-derived custom formats) just muddies this further.
Apple is just blatantly not interested in cooperating with the rest of the market. Mozilla, Google and Microsoft are all part of AoM, along with a bunch of hardware companies and distributors yet Apple is absent and apparently pursuing HEVC instead.
This isn't new either, Apple pushed HLS when others were pushing DASH and MPEG-TS when others were pushing fragmented MP4.
They seem really determined to go their own way and ignore everyone else for some reason.
You're talking nonsense. H.265 is an ITU-T standard and was adopted as the standard for broadcast television ATSC. This isn't an Apple developed codec.
Including the likes of: BBC, Samsung, Dolby, GE, MediaTek, Philips, Mitsubishi, Warner Bros, Sony etc. And as for hardware vendors well AMD, Intel, Nvidia etc all support H.265.

AV1 is already beating HEVC in compression and it's not even finalized yet: https://youtu.be/lzPaldsmJbk?t=2416
