From ZiffDavis article: > QuickTime 6 media player and QuickTime Broadcaster, a free application that aims to simplify using MPEG-4 in live video feeds over the Net.
It was sweet to see “over the Net”…

As someone who hasn't had any exposure to the human stories behind mpeg before, it feels to me like it's been a force for evil since long before 2020. Patents on h264, h265, and even mp3 have been holding the industry back for decades. Imagine what we might have if their iron grip on codecs was broken.
mike_hearn
Possibly, nothing. Codec development is slow and expensive. Free codecs only came along at all because Google decided to subsidize development but that became possible only 15 years or so after MPEG was born, and it's hardly a robust strategy. Plus free codecs were often built by acquiring companies that had previously been using IP licensing as a business model rather than from-scratch development.
Taek
I avoided a career in codecs after spending about a year in college learning about them. The patent minefield meant I couldn't meaningfully build incremental improvements on what existed, and the idea of dilligently dancing around existing patents and then releasing something which intentionally lacked state-of-the-art ideas wasn't compelling.
Codec development is slow and expensive becuase you can't just release a new codec, you have to dance around patents.
mike_hearn
Well, a career in codec development means you'd have done it as a job, and so you'd have been angling for a job at the kind of places that enter into the patent pools and contribute to the standards.
astrange
Software patents aren't an issue in much of the world; the reason I thought there wasn't much of a career in codec development was that it was obvious that it needed to move down into custom ASICs to be power-efficient, at which point you can no longer develop new ones until people replace all their hardware.
derf_
> ...it's hardly a robust strategy.
I disagree. Video is such a large percentage of internet traffic and licensing fees are so high that it becomes possible for any number of companies to subsidize the development cost of a new codec on their own and still net a profit. Google certainly spends the most money, but they were hardly the only ones involved in AV1. At Mozilla we developed Daala from scratch and had reached performance competitive with H.265 when we stopped to contribute the technology to the AV1 process, and our team's entire budget was a fraction of what the annual licensing fees for H.264 would have been. Cisco developed Thor on their own with just a handful of people and contributed that, as well. Many other companies contributed technology on a royalty-free basis. Outside of AV1, you regularly see things like Samsung's EVC (or LC-EVC, or APV, or...), or the AVS series from the Chinese.... If the patent situation were more tenable, you would see a lot more of these.
The cost of developing the technology is not the limitation. I would argue the cost to get all parties to agree on a common standard and the cost to deploy it widely enough for people to rely on it is much higher, but people manage that on a royalty-free basis for many other standards.
mike_hearn
Mozilla is just Google from a financial perspective, it's not an independent org, so the financing point stands.
H.264 was something like >90% of all video a few years ago and wasn't it free for streaming if the end user wasn't paying? IIRC someone also paid the fees for an open source version. There were pretty good licensing terms available and all the big players have used it extensively.
Anyway, my point was only that expecting Google to develop every piece of tech in the world and give it all away for free isn't a general model for tech development, whereas IP rights and patent pools are. The free ride ends the moment Google decide they need more profit, feel threatened in some way or get broken up by the government.
pornel
IP law, especially defence against submarine patents, makes codec development expensive.
In the early days of MPEG codec development was difficult, because most computers weren't capable of encoding video, and the field was in its infancy.
However, by the end of '00s computers were fast enough for anybody to do video encoding R&D, and there was a ton of research to build upon. At that point MPEG's role changed from being a pioneer in the field to being an incumbent with a patent minefield, stopping others from moving the field forward.
cornholio
That's unnecessarily harsh. Patent pools exist to promote collaboration in a world with aggressive IP legislation, they are an answer to a specific environment and they incentivize participants to share their IP at a reasonable price to third parties. The incentive being that you will be left out of the pool, the other members will work around your patents while not licensing their own patents to you, so your own IP is now worthless since you can't work around theirs.
As long as IP law continues in the same form, the alternative to that is completely closed agreements among major companies that will push their own proprietary formats and aggressively enforce their patents.
The fair world where everyone is free to create a new thing, improve upon the frontier codecs, and get a fair reward for their efforts, is simply a fantasy without patent law reform. In the current geopolitical climate, it's very very unlikely for nations where these developments traditionally happened, such as US and western Europe, to weaken their IP laws.
mike_hearn
IP law and the need for extremely smart people with a rare set of narrow skills. It's not like codec development magically happens for free if you ignore patents.
The point is, if there had been no incentives to develop codecs, there would have been no MPEG. Other people would have stepped into the void and sometimes did, e.g. RealVideo, but without legal IP protection the codecs would just have been entirely undocumented and heavily obfuscated, relying on tamper-proofed ASICs much faster.

Maybe you don’t remember the way that the gif format (there was no jpeg, png, or webp initially) had problems with licensing, and then years later having scares about it potentially becoming illegal to use gifs. Here’s a mention of some of the problems with Unisys, though I didn’t find info about these scares on Wikipedia’s GIF or Compuserve pages:
https://www.quora.com/Is-it-true-that-in-1994-the-company-wh...
Similarly, the awful history of digital content restriction technology in-general (DRM, etc.). I’m not against companies trying to protect assets, but data assets historically over all time are inherently prone to “use”, whether that use is intentional or unintentional by the one that provided the data. The problem has always been about the means of dissemination, not that the data itself needed to be encoded with a lock that anyone with the key or means to get/make one could unlock nor that it should need to call home, basically preventing the user from actually legitimately being able to use the data.

It's not just about new codecs. There's also people making products that would use codecs just deciding not to because of the patent hassle.

The release of VP3 as open source predates Google's later acquisition of On2 (2010) by nearly a decade.

"Free codecs only came along at all because Google decided to subsidize development but that became possible only 15 years or so after MPEG was born, and it's hardly a robust strategy"
I don't know about video codecs but MP3 (also part of MPEG) came out of Fraunhofer and was paid by German tax payer money. It should not have been patented in the first place (and wasn't in Germany).
tomrod
Free codecs have been available a long time, surely, as we could install them in Linux distributions in 2005 or earlier?
(I know nothing about the legal side of all this, just remembering the time period of Ubuntu circa 2005-2008).
zappb
Free codecs without patent issues were limited to things like Vorbis which never got wide support. There were FOSS codecs for patented algorithms, but those had legal issues in places that enforce software patents.
thinkingQueen
Who would develop those codecs? A good video coding engineer costs about 100-300k USD a year. The really good ones even more. You need a lot of them. JVET has an attendance of about 350 such engineers each meeting (four times a year).
Not to mention the computer clusters to run all the coding sims, thousands and thousands of CPUs are needed per research team.
People who are outside the video coding industry do not understand that it is an industry. It’s run by big companies with large R&D budgets. It’s like saying ”where would we be with AI if Google, OpenAI and Nvidia didn’t have an iron grip”.
MPEG and especially JVET are doing just fine. The same companies and engineers who worked on AVC, HEVC and VVC are still there with many new ones especially from Asia.
MPEG was reorganized because this Leonardo guy became an obstacle, and he’s been angry about ever since. Other than that I’d say business as usual in the video coding realm.
rwmj
Who would write a web server? Who would write Curl? Who would write a whole operating system to compete with Microsoft when that would take thousands of engineers being paid $100,000s per year? People don't understand that these companies have huge R&D budgets!
(The answer is that most of the work would be done by companies who have an interest in video distribution - eg. Google - but don't profit directly by selling codecs. And universities for the more research side of things. Plus volunteers gluing it all together into the final system.)

> Who would write a whole operating system to compete with Microsoft when that would take thousands of engineers being paid $100,000s per year?
You might be misunderstanding that almost all of Linux development is funded by the same kind of companies that fund MPEG development.
It's not "engineers in their basement", and never was
https://www.linuxfoundation.org/about/members
e.g. Red Hat, Intel, Oracle, Google, and now MICROSOFT itself (the competitive landscape changed)
This has LONG been the case, e.g. an article from 2008:
https://www.informationweek.com/it-sectors/linux-contributor...
2017 Linux Foundation Report: https://www.linuxfoundation.org/press/press-release/linux-fo...
Roughly 15,600 developers from more than 1,400 companies have contributed to the Linux kernel since the adoption of Git made detailed tracking possible
The Top 10 organizations sponsoring Linux kernel development since the last report include Intel, Red Hat, Linaro, IBM, Samsung, SUSE, Google, AMD, Renesas and Mellanox
---
curl does seem to be an outlier, but you still need to answer the question: "Who would develop video codecs?" You can't just say "Linux appeared out of thin air", because that's not what happened.
Linux has funding because it serves the interests of a large group of companies that themselves have a source of revenue.
(And to be clear, I do not think that is a bad thing! I prefer it when companies write open source software. But it does skew the design of what open source software is available.)
mike_hearn
Google funding free stuff is not a real social mechanism. It's not something you can point to and say that's how society should work in general.
Our industry has come to take Google's enormous corporate generosity for granted, but there was zero need for it to be as helpful to open computing as it has been. It would have been just as successful with YouTube if Chrome was entirely closed source and they paid for video codec licensing, or if they developed entirely closed codecs just for their own use. In fact nearly all Google's codebase is closed source and it hasn't held them back at all.
Google did give a lot away though, and for that we should be very grateful. They not only released a ton of useful code and algorithms for free, they also inspired a culture where other companies also do that sometimes (e.g. Llama). But we should also recognize that relying on the benevolence of 2-3 idealistic billionaires with a browser fetish is a very time and place specific one-off, it's not a thing that can be demanded or generalized.
In general, R&D is costly and requires incentives. Patent pools aren't perfect, but they do work well enough to always be defining the state-of-the-art and establish global standards too (digital TV, DVDs, streaming.... all patent pool based mechanisms).
raverbashing
These are bad comparisons
The question is more, "who would write the HTTP spec?" except instead of sending text back and forth you need experts in compression, visual perception, video formats, etc
thinkingQueen
Are you really saying that patents are preventing people from writing the next great video codec? If it were that simple, it would’ve already happened. We’re not talking about a software project that you can just hack together, compile, and see if it works. We’re talking about rigorous performance and complexity evaluations, subjective testing, and massive coordination with hardware manufacturers—from chips to displays.
People don’t develop video codecs for fun like they do with software. And the reason is that it’s almost impossible to do without support from the industry.
roenxi
> It’s like saying ”where would we be with AI if Google, OpenAI and Nvidia didn’t have an iron grip”.
We'd be where we are. All the codec-equivalent aspects of their work are unencumbered by patents and there are very high quality free models available in the market that are just given away. If the multimedia world had followed the Google example it'd be quite hard to complain about the codecs.
thinkingQueen
That’s hardly true. Nvidia’s tech is covered by patents and licenses. Why else would it be worth 4.5 trillion dollars?
The top AI companies use very restrictive licenses.
I think it’s actually the other way around and AI industry will actually end up following the video coding industry when it comes to patents, royalties, licenses etc.
somethingsome
Hey, I attend MPEG regularly (mostly lvc lately), there's a chance we’ve crossed paths!
mschuster91

How about governments? Radar, Laser, Microwaves - all offshoots of US military R&D.
There's nothing stopping either the US or European governments from stepping up and funding academic progress again.
rs186
Yeah, counting on governments to develop codecs optimized for fast evolving applications for web and live streaming is a great idea.
If we did that we would probably be stuck with low-bitrate 720p videos on YouTube.
Reason077
> "Patents on h264, h265, and even mp3 have been holding the industry back for decades. Imagine what we might have if their iron grip on codecs was broken."
Has AV1 solved this, to some extent? Although there are patent claims against it (patents for technologies that are fundamental to all the modern video codecs), it still seems better than the patent & licensing situation for h264 / h265.
afroboy
The power of H264 and H265 comes from pirates, and since AV1 team don't work with pirates then it will always be inferior to H265.
Just check pirated releases of TV shows and movies.
philistine
At least for MP3, our collective nightmare is over. MP3 is completely patent-unencumbered and can be used freely.
jbverschoor
Enough codecs out there. Just no adoption.
egeozcan
This might be an oversimplification, but as a consumer, I think I see a catch-22 for new codecs. Companies need a big incentive to invest in them, which means the codec has to be technically superior and safe from hidden patent claims. But the only way to know if it's safe is for it to be widely used for a long time. Of course, it can't get widely used without company support in the first place. So, while everyone waits, the technology is no longer superior, and the whole thing fizzles out.
jbverschoor
Jxl has been around for years.
Av1 for 7
The problem is every platform wants to force their own codec, and get earn royalties from the rest of the world.
They literally sabotaging it. Jxl support even got removed from chrome.
Investment in adopting in software is next to 0.
In hardware it’s a different story, and I’m not sure to what extent which codec can be properly accelerated
Taek
Companies only need a big incentive to invest in new codecs because creating a codec that has a simple incremental improvement would violate existing patents.
rs186
Not all codecs are equal, and to be honest, most are probably not optimized/suitable for today's applications, otherwise Google wouldn't have invented their own codec (which then gets adopted widely, fortunately).
wheybags
Yes, because mpeg got there first, and now their dominance is baked into silicon with hardware acceleration. It's starting to change at last but we have a long way to go. That way would be a lot easier if their patent portfolio just died.
TiredOfLife
Because every codec has 3+ different patent pools wanting rent. Each with different terms.
fidotron
The fact h264 and h265 are known by those terms is key to the other part of the equation: the ITU Video Coding Experts Group has become the dominant forum for setting standards going back to at least 2005.
marcodiego
> My Christian Catholic education made and still makes me think that everybody should have a mission that extends beyond their personal interests.
I remember this same guy complaining investments in the MPEG extortionist group would disappear because they couldn't fight against AV1.
He was part of a patent Mafia is is only lamenting he lost power.
Hypocrisy in its finest form.

Any link to his comment?

> all the investments (collectively hundreds of millions USD) made by the industry for the new video codec will go up in smoke and AOM’s royalty free model will spread to other business segments as well.

He is not a coder, not a researcher, he is only part of the worst game there is in this industry: a money maker from patents and "standards" you need to pay for to use, implement or claim compatibility.
cnst
His argument is blatantly invalid.
He first points out that a royalty-free format was actually better than the patent-pending alternative that he was responsible for pushing.
In the end, he concludes that the that the progress of video compression would stop if developers can't make money from patents, providing a comparison table on codec improvements that conveniently omits the aforementioned royalty-free code being better than the commercial alternatives pushed by his group.
Besides the above fallacy, the article is simply full of boasting about his own self-importance and religious connotations.
DragonStrength
You missed the first part of that quote:
> At long last everybody realises that the old MPEG business model is now broke
And the entire post is about how dysfunctional MPEG is and how AOM rose to deal with it. It is tragic to waste so much time and money only to produce nothing. He's criticizing the MPEG group and their infighting. He's literally criticizing MPEG's licensing model and the leadership of the companies in MPEG. He's an MPEG member saying MPEG's business model is broken yet no one has a desire to fix it, so it will be beaten by a competitor. Would you not want to see your own organization reform rather than die?
Reminder AOM is a bunch of megacorps with profit motive too, which is why he thinks this ultimately leads to stalled innovation:
> My concerns are at a different level and have to do with the way industry at large will be able to access innovation. AOM will certainly give much needed stability to the video codec market but this will come at the cost of reduced if not entirely halted technical progress. There will simply be no incentive for companies to develop new video compression technologies, at very significant cost because of the sophistication of the field, knowing that their assets will be thankfully – and nothing more – accepted and used by AOM in their video codecs.
> Companies will slash their video compression technology investments, thousands of jobs will go and millions of USD of funding to universities will be cut. A successful “access technology at no cost” model will spread to other fields.
Money is the motivator. Figuring out how to reward investment in pushing the technology forward is his concern. It sounds like he is open to suggestions.
dostick
The article does not give much beyond what you already read in the title. What obscure forces and how? Isn’t it an open standards non-profit organisation, then what could possible hinder it? Maybe because technologically closed standards became better and nonprofit project has no resources to compete with commercial standards? USB Alliance have been able to work things out, so maybe compression standards should be developed in similar way?
baobun
Supposedly the whole story is told in their linked book.
eggspurt
From Leonardo, who founded MPEG, on the page linked: "Even before it has ceased to exists, the MPEG engine had run out of steam – technology- and business wise. The same obscure forces that have hijacked MPEG had kept it hostage to their interests impeding its technical development and keeping it locked to outmoded Intellectual Property licensing models delaying market adoption of MPEG standards. Industry has been strangled and consumers have been deprived of the benefits of new technologies. From facilitators of new opportunities and experiences, MPEG standards have morphed from into roadblocks."
mananaysiempre
One detail for context: when “closing” MPEG, he also deleted all of its all pages and materials and redirected them to the AI stuff.
karel-3d
I... don't understand how AI related to video codecs. Maybe because I don't understand either video codecs or AI on a deeper level.
tdullien
Every predictor is a compressor, every compressor is a predictor.
If you're interested in this, it's a good idea reading about the Hutter prize (https://en.wikipedia.org/wiki/Hutter_Prize) and going from there.
In general, lossless compression works by predicting the next (letter/token/frame) and then encoding the difference from the prediction in the data stream succinctly. The better you predict, the less you need to encode, the better you compress.
The flip side of this is that all fields of compression have a lot to gain from progress in AI.

It is like upscaling. If you could train AI to "upscale" your audio or video you could get away with sending a lot less data. It is already being done with quite amazing results for audio.
jl6
It has long been recognised that the state of the art in data compression has much in common with the state of the art in AI, for example:
ddtaylor
Some view these as so interconnected that they will say LLMs are "just" compression.
pjc50
Which is an interesting view when applied to the IP. I think it's relatively uncontroversial that an MP4 file which "predicts" a Disney movie which it was "trained on" is a derived work. Suppose you have an LLM which was trained on a fairly small set of movies and you could produce any one on demand; would that be treated as a derived work?
If you have a predictor/compressor LLM which was trained on all the movies in the world, would that not also be infringement?
Retr0id
AI and data compression are the same problem, rephrased.

May be, we are couple of years away from experiencing patent free video codecs based on deep learning.
DCVC-RT (https://github.com/microsoft/DCVC) - A deep learning based video codec claims to deliver 21% more compression than h266.
One of the compelling edge AI usecases is to create deep learning based audio/video codecs on consumer hardwares.
One of the large/enterprise AI usecases is to create a coding model that generates deep learning based audio/video codecs for consumer hardwares.
gcr
Goodbye MPEG group, and to be frank, good riddance I think. I'm glad that open codecs are now taking over on the frontier of SOTA encoding.
Maybe these sorts of handshake agreements and industry collaboration were necessary to get things rolling in 198x. If so, then I thank the MPEG group for starting that work. But by 2005 or so when DivX and XviD and h264 were heating up, it was time to move beyond that model towards open interoperability.

This makes zero sense, right? Even if this was applicable, why would it need a standard? There is no interoperability between game servers of different games

I think if IP rights holders were mandated to pay property tax it would make the system much healthier.
londons_explore
This. You should have to declare the value of a patent, and pay 1% of that value every year to the government. Anyone else can force-purchase it for that value, but leaving you with a free perpetual license.
LeafItAlone
Wouldn’t that only help the “big guys” who can afford to pay the tax?
MyOutfitIsVague
Presumably the tax would be based on some estimated value of the property, and affordability would therefore scale.

dathinab
sure, it being a 6 digit code which has potential for social engineering can be an issue
like similar to if you get a "your login" yes/no prompt on a authentication app, but a bit less easy to social engineer but a in turn also suspect to bruteforce attacks (similar to how TOTP is suspect to it)
through on the other hand
- some stuff has so low need of security that it's fine (like configuration site for email news letters or similar where you have to have a mail only based unlock)
- if someone has your email they can do a password reset
- if you replace email code with a login link you some cross device hurdles but fix some of of social enginering vectors (i.e. it's like a password reset on every login)
- you still can combine it with 2FA which if combined with link instead of pin is basically the password reset flow => should be reasonable secure
=> eitherway that login was designed for very low security use cases where you also wouldn't ever bother with 2FA as losing the account doesn't matter, IMHO don't use it for something else :smh:

Big companies abused the setup that he was responsible for. Gentlemen's agreements to work together for the benefit of all got gamed into patent landmines and it happened under his watch.
Even many of the big corps involved called out the bullshit, notably Steve Jobs refusing to release a new Quicktime till they fixed some of the most egregious parts of AAC licencing way back in 2002.
