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.

yep
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.
It’s not an easy problem.
Aesthetics over function; style over substance. If that's their web design policy it's likely their policy in all other aspects.
I'm also not sure that they're aware that intellectual property rights no longer exist in the US. If AV2 was vibe coded, there would be no case.
…for copyright. Not for anything else. Patents would still apply.
Otherwise it was under a constant DDoS by the AI bots.
For instance, MCP, static sites that are easy to scale, a cache in front of a dynamic site engine
Our documentation and a main website are not fronted by this protection, so they're still accessible for the scrapers.
What am I missing that explains the gap between this and “constant DDoS” of the site?
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.
- 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.
I think the world gains more if the VLAN team focuses on their amazing, free contribution to the world, than if they spend the same time trying to figure out how to save you two clicks.
We all hate that this is happening, but you don't need to attack everyone that is unfortunately caught up in it.
If you have discovered such an option, you could get very wealthy: minimizing friction for humans in e-commerce is valuable. If you're a drive-by critic not vested in the project, then yours is an instance of talk being cheap.
Keep in mind that those kinds of services: - should not be MITMed by CDNs - are generally ran by volunteers with zero budget, money and time-wise
I've seen several posts on HN and elsewhere showing many bots can be fingerprinted and blocked based on HTTP headers and TLS.
For the bots that perfectly match the fingerprint of an interactive browser and don't trigger rate limits, use hidden links to tarpits and zip bombs. Many of these have been discussed on HN. Here's the first one that came to memory: https://news.ycombinator.com/item?id=42725147
It's rarely been the citizens that have been the problem, but the governments and companies that seek the use the network connection for their overwhelming benefit.
Re (above):
> Not on topic, but wow the internet has very quickly devolved into: click -> "making sure you're not a bot", click -> "making sure you're a human", click -> "COOKIES COOKIES COOKIES", click -> "cloudflare something something"
That being said, so many of the plebs suck. Like 2% will ruin everything for everyone.
But whether you agree with me or not, most paradigm shifting changes come from billionaires/corps because they are the only ones with the money to pull off massive shifts. Most innovation is not grassroots and heavily funded by the “elites”. This is how most successful countries have been for atleast the last 100 years. So billionaires add a lot of value even as they cause a lot of pain.
The solution in my mind is we absolutely need uncapped billionaires but they need to be effectively taxed (not like 90% but closer to 50%) and they have to have absolutely no influence on the government.
it is incredibly annoying but what can you do? AI scrapers ruined the web.
Then I press the X to close the all-caps banner commanding me to install the app, upon which I get sent to the app store. Users of the website refer to it as an app.
Wow, this gitlab instance looked so much cleaner/simpler and less clunky than my past experiences! Also loaded really fast on first page load as well as subsequent actions

... it says "fast and small AV1 video stream decoder"
... should probably be "AV2" ?
Happy, AV2 decoding already here.
:)
>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 :)
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.

C compilers, Rust compilers, and assemblers are all deterministic.
I wonder IFF Rust had an effects system that a Jasmin MIR transform (ie like SPIRV is for shaders) would be useful?
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
