Intel Discontinues High-Speed, Open-Source H.265/HEVC Encoder Project (phoronix.com) 37
Phoronix's Michael Larabel reports: As part of Intel's Scalable Video Technology (SVT) initiative they had been developing SVT-HEVC as a BSD-licensed high performance H.265/HEVC video encoder optimized for Xeon Scalable and Xeon D processors. But recently they've changed course and the project has been officially discontinued. [...] The SVT-AV1 project a while ago was already punted to the Alliance for Open Media (AOMedia) project and one of its lead maintainers having joined Meta from Intel two years ago. SVT-AV1 continues excelling great outside the borders of Intel but SVT-HEVC (and SVT-VP9) have remained Intel open-source projects but at least officially SVT-HEVC has ended.
SVT-HEVC hadn't seen a new release since 2021 and there are already several great open-source H.265 encoders out there like x265 and Kvazaar. But as of a few weeks ago, SVT-HEVC upstream is now discontinued. The GitHub repository was put into a read-only state [with a discontinuation notice]. Meanwhile SVT-VP9 doesn't have any discontinuation notice at this time. The SVT-VP9 GitHub repository remains under Intel's Open Visual Cloud account although it hasn't seen any new commits in four months and the last tagged release was back in 2020.

Intel has had performance cores (p-cores), and efficient (e-cores) for a couple iterations now. Is this not that?
Intel's also advertising NPUs (neural processing units) for its newest lineup...

MMX was a poor man's VIS - they blatantly ripped it off from Sun. It's the same "overlay integer SIMD on FPU registers" crap, except they somehow managed to make it even worse than Sun's implementation. What were the innovative features in the 8086? The 20-bit address space was barely an upgrade over the 16-bit address spaces on the 6502 and Z80 families, and the segmented memory model ended up being a liability that made extending the address space any further far more difficult than it needed to be.

I don't think the 8086 architecture is innovative. I think Intel has had moments of brilliance, like LightPeak which became Thunderbolt. PCI was also a solid design, taking some of the ideas from NuBus and using reflected wave signalling for better stability and lower power consumption at higher frequencies. PCI Express is pretty good, too.
Even the 4004 was pretty innovative, particularly with the trade-offs it made to make circuit board designs simpler and scalable. The iAPX432 CPU was innovative, alth

The money drives it. It either gets incorporated in other projects or someone with time, motivation, and personal interest takes the reigns that otherwise would have been squeezed out by the corporate mentality.
It did what it needed for the time which was to sell server processors for cloud encoding.

H.265/HEVC is being kicked to the curb by everyone at this point. The licensing, pricing, encumberments, and risk are all just too high. MPEGLA got too greedy and shot themselves in the foot. Lots of big companies have jumped ship, and together, designed their own, completely open and royalty-free specification, AV1:

The problem now is just waiting for hardware encoders/decoders to catch up. Most all video chips/cards now have AV1 hardware decoding support, but it will take a while for those with older systems to eventually upgrade. Most also have encoding support as well. From what I understand, AV1 is equal to or better than HEVC in every way, except encoding speed, and that has been rapidly improving. It took a long time to develop and get it going, but it is now starting its trajectory to be "the" standard for general video storage/streaming/etc.

Except it's not MPEG-LA. In fact, MPEG-LA wasn't greedy enough, so a bunch of patent holders went and formed the HEVC Alliance because they hated how little the MEPG-LA wanted for their patents.
So it's the fact licensing requires two licenses and one is far more expensive than the one you had.
AV1 is not universal yet - it's only been in hardware this current gen of SoCs, which means it's in maybe the flagship SoCs, but not in the midrange and lower. So those users will likely not have hardware AV1 for another 3-5 years at a minimum.

Thanks for filling in the details. I didn't know exactly which organization(s) screwed the pooch.

Agreed. I only projected it is certainly on the path to be universal.

I am not up on current AV1 hardware compatibility, but, the ThinkPad X13 AMD Gen 3 laptop (AMD Ryzen 5 Pro 6650U, Radeon 660M) I bought almost 2 years ago (which had been out a year, I think) has AV1 hardware decoding.
On my AMD Ryzen 7 3700X Linux desktop, which is older and has an ancient Nvidia card it in, there is no hardware AV1 decoding, but the CPU is fast enough that Firefox software-decodes AV1 YouTube videos with no problems at all (about 20% CPU on one core for 720P, 30% for 1080P). Maybe someday I will get a new video card (maybe an AMD one).
Now, ENCODING AV1 would be painful, indeed, without hardware acceleration :) I am still encoding my own stuff to H.264.

SVT-AV1 on Handbrake has gotten much, much better lately. I switched to encoding with it and it can encode much smaller in the same time, or half the size of H.264 in three times the encoding time.

That is false, I mean not very false, but partially it does go back a couple of generations on general purpose stuff and longer than that on special purpose stuff. E.g. Qualcomm introduced AV1 decode in 2022. Samsung SoCs 2021. Intel in their CPUs in 2021. NVIDIA in 2021. Samsung and LG in their TVs in 2020. AMD in all GPUs and iGPUs in 2020. Mediatek in their SoCs 2020.
SO at this point if you bought something in the last couple of years chances are it has native AV1 decode support. Unless you have a Qualco

All of the modern Nvidia cards do H.264, H.265, HEVC, and AV1. Usually when I want to do anything but just rip to the original format, It's because I'm trying to put content on a specific limited device. Then I have to use whatever codec it supports...

While licensing is a concern, it's not the biggest expense for most professional content creators and distributors. Of course, we'd all like it if we didn't have to deal with this.

Citation needed. We can find plenty of citations showing all major platforms accounting for the majority of video bandwidth are abandoning HEVC. Netflix, Disney Amazon etc delivery AV1 by default with a HEVC only as a fallback stream.
Even Google caved and enabled it in Chrome a could have years ago.
Enabling playback does not indicate support. Google infamously not only never used HEVC on Youtube, but was an early adopter of AV1 and just made AV1 the default playback format on Android. Their shift is clearly away from HEVC without ever supporting it internally.
