What are you even implying?
I think they mean that video decoders and encoders tend to have custom assembly code for speedup.

#53Not 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"
Nearly every single website I'm not logged into these days want me to "confirm I'm not a bot".
it is incredibly annoying but what can you do? AI scrapers ruined the web.

We had to set it up on the parts of VideoLAN infra so the service would remain usable. Otherwise it was under a constant DDoS by the AI bots.
I highly doubt there is no other technically feasible option to block the AI bots.
You end up blocking not just bots, but many humans too. When I clicked on the link and the bot block came up, I just clicked back.
I think HN posts should have warnings when the site blocks you from seeing it until you somehow, maybe, prove you are human.

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.
Re: Dav2d
#56We must not continue to develop media codecs in memory unsafe languages. Small, auditable sections can opt-out perhaps, but choosing default-unsafe for this type of software is close to professional negligence.
Of the 3 software AV1 encoders, the only one that is fully dead is the Rust encoder (rav1e). If people truly wanted memory safe encoders/decoders, they would fund and develop them.
Fully dead in what sense? Seems like it still has active development to me.

And who ever heard of this in the majority of the world? It was news to me, I'm white and European btw. 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.

So no one below the age of 60 is aware of this.

The internet is such a Tragedy of the Commons… its citizens that act selfishly and in bad faith will slowly make it unusable.
> its citizens that act selfishly and in bad faith will slowly make it unusable 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.

wat. The protections in place that the OP is talking about are almost entirely due to (not government and company) bad actors.

It hasn't had any proper quality/speed improvements in years. Only thing that has changed is updating deps and some bug fixes.

They’re more of a D4vd fan
