dav2d is the fastest AV2 decoder on all platforms :)
Targeted to be small, portable and very fast.
If you're out of the loop like me:
AV2 is the next-generation video coding specification from the Alliance for Open Media (AOMedia). Building on the foundation of AV1, AV2 is engineered to provide superior compression efficiency, enabling high-quality video delivery at significantly lower bitrates. It is optimized for the evolving demands of streaming, broadcasting, and real-time video conferencing.
They've done the same thing with AV1, and I can't see that having prevented adoption, nor can I imagine Sisvel wanting to poke the bear that is AOMedia unless they're certain their case is absolutely watertight.

Yup. The Dolby/Disney vs Snapchat lawsuit is going to be the first one. So far it's only been filed.
The big question is if AOMedia is going to make good on their Mutually Assured Destruction promise of using their patent and financial war chest to to countersue into oblivion anyone trying to go after AV1 adaptors.
I would love to live in a world where this happens. I will place big bets that it will, regrettably not happen.
Telaneo 10 hours ago [-]
Same, which is what makes it seem to me that that case is absolutely not watertight. Those patents are probably all about esoteric minutiae (to be fair, that's because that's what it takes to make a better video codec these days) and everything and anything that can seemingly be connected to AV2 (or AV1 for that matter), many of which have only gotten a patent because the person approving it only barely understands what it's saying.

In either case the big players behind the codec can defend themselves but a small one just picking it up downstream as OSS can't.

What am I missing that explains the gap between this and “constant DDoS” of the site?
thresh 8 hours ago [-]
You cant really cache the dynamic content produced by the forges like Gitlab and, say, web forums like phpbb. So it means every request gets through the slow path. Media/JS is of course cached on the edge, so it's not an issue.
Even when the amount of AI requests isnt that high - generally it's in hundreds per second tops for our services combined - that's still a load that causes issues for legitimate users/developers. We've seen it grow from somewhat reasonable to pretty much being 99% of responses we serve.
Can it be solved by throwing more hardware at the problem? Sure. But it's not sustainable, and the reasonable approach in our case is to filter off the parasitic traffic.

I don't know how GitLab became so disgustingly slow. But yeah, I'm not surprised bots can easily bring it to its knees.
nijave 8 hours ago [-]
I think there's a few things at play here
- AI scrapers will pull a bunch of docs from many sites in parallel (so instead of a human request where someone picks a single Google result, it hits a bunch of sites)
- AI will crawl the site looking for the correct answer which may hit a handful of pages
- AI sends requests in quick succession (big bursts instead of small trickle over longer time)
- Personal assistants may crawl the site repeatedly scraping everything (we saw a fair bit of this at work, they announced themselves with user agents)
- At work (b2b SaaS webapp) we also found that the personal assistant variety tended to hammer really computationally expensive data export and reporting endpoints generally without filters. While our app technically supported it, it was very inorganic traffic
That said, I don't think the solution is blanket blocks. Really it's exposing sites are poorly optimized for emerging technology.

That codecs should be written in safer languages given that they usually process untrusted files. There have been a number of serious hacks from file parsing bugs due to them being written in unsafe languages.
There's literally a DSL designed for this purpose (Wuffs) so it would be interesting to hear why they didn't use it.
brigade 9 hours ago [-]
There's an order of magnitude difference in speed requirements between file format parsing and image decoding, then another order of magnitude difference to video decoding. Even rav1d reuses dav1d's assembly (most of the actual runtime) to approach its speed.
The people who write DSLs for video codec asm, or who claim that it's fine to use intrinsics or X higher-level language and it will still be fast enough to be usable, are simply wrong and have never been able to demonstrate otherwise.
Having said that I do think you could write a DSL to generate safe performant asm for a video codec. Just not a platform-independent one. It would still have to be asm.

Cryptography and video codecs are notable exceptions, they put a lot of effort to making the code provably memory safe: no recursion, limited use of stack variables, no dynamic allocations, etc. As a result, memory safe languages bring nothing but trouble by making it non deterministic, that’s especially true for crypto where compiler “optimisations” guarantee you side channels attacks.

For the codec itself, the majority of it is performance sensitive and often has a significant amount of assembly even, so a memory safe language doesn't change much.
However for the container/extractor... those should absolutely be in a memory safe language, and those are were a lot of the exploits/crashes are, too, as metadata is more fuzzy.
As a practical example of this see something like CrabbyAVIF. All the parser code is rust, but it delegates to dav1d for the actual codec portion

Did you know the US consititues about 4% of humans? When we look at adults and age range that likely ever hear of D4vd we are talking probably considerably less that 1%.
The rest of humanity has no negative association with these four letters.
It's a recurring headline on the rolling news channels on broadcast TV right now - and it's on the front-page of Reddit for me as well.

Potentially... supposing the criminal investigation into this uncovers a hitherto unknown organ harvesting scheme operating within the global music records industry; the subsequent police dragnet implicates significant proportion of the world's music stars and record labels and generates continual major headlines and criminal convictions - with all their lurid details - all for multiple decades from now on.
It's quite ridiculous when I put it that way, but this is basically the same thing as Epstein's network, just with a different crime; and Epstein was already in the news almost 20 years ago from his first conviction.
...so back in 2009, back when everyone was building their own social-network websites and online dating services, and supposing your real-name was also Epstein, so you called it "EpsteinLoveIsland.com" - would you have changed the name back then?
So no one below the age of 60 is aware of this.

Why did you feel the need to explicitly specify that you're white as one of the reasons you didn't hear the news?
I'm not american either, but the news is all over social media platforms like reddit and Twitter, it's hard to turn a blind eye on them.
dav1d - started in 2018
d4vd - started composing in 2021
>look inside
>it's C
Since dav2d is newer it has a higher fraction of C, but not enough for it to be the main language in the codebase :)
Decoders are one of the best places for rust because they are both performance critical and security critical.
JPEG-XL couldn’t get off the ground until they recreated the decoder in Rust since none of the browsers wanted to touch it. And the apps that did utilise the C based libjxl ended up hit with vulnerabilities in it.
There's literally a DSL designed for this purpose (Wuffs) so it would be interesting to hear why they didn't use it.
Having said that I do think you could write a DSL to generate safe performant asm for a video codec. Just not a platform-independent one. It would still have to be asm.

One day in the mysterious future the AV3 decoder will be dav3d.

I wonder IFF Rust had an effects system that a Jasmin MIR transform (ie like SPIRV is for shaders) would be useful?

C compilers, Rust compilers, and assemblers are all deterministic.
Within a version, yes, but not cross version. Different versions of GCC/Clang etc can give you completely different code.
Really? How many codecs have your neighbors contributed money for the development of, just curious.
However for the container/extractor... those should absolutely be in a memory safe language, and those are were a lot of the exploits/crashes are, too, as metadata is more fuzzy.
As a practical example of this see something like CrabbyAVIF. All the parser code is rust, but it delegates to dav1d for the actual codec portion
