There is actually something, but I don't know what it is.
For sure gcc won't compile.
What language will it be in? It is not known.
The creator dreams of x266, but currently works in vvc.
I don't know what single file x266.cpp files are. There is probably some assembler.

The ?266's RISC-V NON-Standard Vector Extension ONLY compile and disassembly by ?266 project modified llvm suite. You may build bu yourself or please contract to get prebuilt Centos-6 binary package.

Well, I contacted Multicoreware anyway with my Sky email, asking them for some info.
Let's see if they reply.

The spec is barely out. Finalised last August, but profiles were still not set then. VTM Reference Software was barely catching up in October and VTM 11.0 only released two days ago. Conformance test wasn't finalised either.

I mean normally these sort of "cleaning up" takes up to a year. So I think they are doing well so far.

Cutting edge technologies take time to be implemented.
22.2 channel aac audio spec was released years ago, and we barely just had a preliminary support in the latest version, implemented by jeeb.
Sometimes you have to be patient ;)

Having a decoder is basically the first thing you want when supporting a codec, so those commits are more than welcomed.

The Streaming Codec Landscape in 2021
What Happened in 2020?
This past year saw the launch of two MPEG codecs — VVC and Low Complexity Enhancement Video Coding (LCEVC) — and the continued development of Essential Video Coding (EVC). You can read more about VVC’s technical background here. I reviewed Fraunhofer’s VVC encoder and decoder, respectively called VVenC and VVdeC, for Streaming Media Magazine here. As Table 2 shows, VCVenC proved 39% more efficient than x265 in terms of quality, but it took 10x longer to encode, and it was 3.7x slower during decode.

Regarding royalties, the intellectual property that was contributed to VVC came from many parties, and VVC will be royalty-bearing, although we probably won’t know what the royalty policy will look like until mid-2021 or later.

An error in the quoted statement here - LCEVC isn't a codec. It's a standardized postprocessing with metadata technology that sits on top of codecs. It could be applied to H.264, HEVC, and/or VVC.

Is LCEVC mpeg5 paid? I don't see free libraries, and the final standard was in October 2020.
https://www.lcevc.org/
Weird. nothing is said about the new AV2 codec.

Interestingly that image from ateme shows that AV2 will be ratified in ~2026. I haven't seen a timeline for AV2 before. I'm glad they aren't going to try and release a new one every 3 years which i think was the original intention. This way AV1 will have time to become popular. Also nearly all the h264 patents will have expired by then. I'm sure that some of the patents that Sisvel claim AV1 violates will have expired by then too.

Giving too much credit for Google or Alliance Open Media, their original goal was new codec every "2" years. /s

Speaking of H264 patents, I am eagerly waiting for the patent free EVC baseline to test. Which is pretty much all H.264 expired or soon to be expired patents.

There are certainly people interested in getting AV2 standardized before 2026. VVC's technical superiority over AV1 is pretty substantial. And essential patents are expiring every year, so there are plenty of techniques that couldn't be implemented in AV1 that are already available for AV2.

BAD NEWS GUYS... The Media Coding Industry Forum (MC-IF) whose members make up the majority of VVC patents have been unable to achieve concencus in picking a patent licensing pool administrator so there will be 2 PATENT POOLS!!!!! One of the pools is 'Access Advance', the other is 'MPEG-LA'. Source: https://a7dce6fd-e8f0-45f7-b0b0-255c...0482debab7.pdf

Clearly they haven't learnt their lesson from the HEVC patent licensing problems!

LOL, It is Access Advance ( Previously HEVC Advance ) and MPEG LA again. I am starting to think there are some bad blood between the two.

And even Google is part of Access Advance Licensor.

Despite the public hatred against MPEG-LA, they have been the one offering cheaper HEVC licensing.

Yeah... this is not good news for general availability...
Let's see how it's gonna play out...

Well We are only 1 year away from 3nm. Whatever cost, power or other obstacles AV1 had with mobile hardware decoder will diminish with the advance of computing and design.

TSMC 5nm node has higher transistor cost then 7nm, and 3nm will probably follow that trend, so not sure how 3nm will help if the reason for the lack of av1 decoders was cause of roi on transistor budget.

Edit. initially ofc, but the trend is that transistor cost isnt drastically reduced anymore from die shrinks.
