Hacker news doesn't generate much traffic, despite what people are saying.

The host here has a limit of 160000 files served each day. That is extremely low. If the site has an icon, css, a js file and a few images it's 10 files each visit. That's will limit it to 16k visits/day. If there are more files loaded it might just handle a few thousand visits, and they have received more than that from HN now.

'AV2 decoding is roughly five times more complex than AV1 decoding. In practice, that means software running on today’s hardware will struggle to decode AV2 in real time without careful, architecture-specific optimization'

AV1 software decoding is already very intensive so AV2 decoding benchmarks are the next thing that would be really interesting (or mortifying) to see.

Intel's Arc dGPUs were really compelling for dedicated AV1 encode and decode, especially the small form factor of some cards. You could even fit it as a secondary card in a PC dedicated to recording and encode workflows for OBS.

Hope we get a similar option with future lineups that support AV2, especially given how popular video creation and streaming are now.

Is there a compelling reason encoding needs to be done locally?

The point of encoding is to reduce downstream bandwidth for the viewer, and upstream bandwidth for the distribution network.

The content creator only needs to upload it once.

esposm03

Yes.

An uncompressed 1080p, 60fps video with 24-bit color depth would need around 3Gbps to be streamed. And even if you don't need to stream it, that would still consume a sizeable portion of the write throughput of the fastest SSDs currently available; if you go up to 4K, you'd actually exceed that by a lot (not to mention, 1tb of storage would last for about 10 minutes of video).

If you don't encode locally as the video is created, you either need to store RAW frames which takes enormous amount of storage, or you use a different format and suffer quality loss by transcending.

tverbeure

> you use a different format and suffer quality loss by transcending.

Compressing to AV1/h264/265 etc is really only done for the final version, but that doesn't mean that videos are stored in RAW format during editing, where it is very common to store frames locally in Apple ProRes, Avid DNxHD, or some other compressed format that's targeted towards professional editing.

Contrary to AV1 or whatever similar format which offer compression ratios of 1000x and more, these formats have a compression ratio of around 10x. They are very simple, and the quality loss is low enough that it doesn't matter. They also tend to store images with 30 bits per pixel instead of the 24 bpp that's normally used for streaming.

Hardly niche. My laptop isn't new and it has hardware AV1 decoding and encoding. My 10 year old iPhone 7 can play 1080p AV1 video in software for over 200 minutes with VLC. The iPhone 7 was released in 2016, a year and a half before AV1. The dav1d decoder is mighty.

Netflix uses AV1: https://netflixtechblog.com/av1-now-powering-30-of-netflix-s...

YouTube uses AV1. It's tough to be more mainstream than that.

Right click on a YouTube video and select Stats for Nerds. If your system is capable of it, chances are it will be playing back in AV1.

Most of the YouTube videos I watch these days are AV1 encodes. Sometimes it's in VP9 and occasionally it's H.264.

weiliddat

Supported is different from doing it well though. You do notice the performance hit even on TVs that playback YouTube videos on AV1.

Even on 1080p videos running on AV1 on 1x, the TV system bogs down and any kind of interaction has a variable 1-3s lag. On some TVs if you do 1.25x the TV automatically "downgrades" the resolution to 480p to avoid dropping frames.

I wish there was an option to still use VP9 / H.264 on those systems (even limited to 1080p).

Yeah I could imagine the AV1 codec sticking around for a very long while, even as a fallback for AV2.

A codec spec isn't done until there is at least one decoder developed in the field. So reference + 1. The field implementations often become the de facto spec.

Reading the MPEG1 specs back in the 90s as a child opened my eyes to how to define complex systems. For a media coding standard, they spent most of their time saying how to interpret encoded bytes, which I realized is genius. Be descriptive about decoding and you don't have to be prescriptive about encoding. Encoding is where you can apply all the creativity, but you need to provide a way to have a shared understanding of the encoded bytes.

Modern video services perform multiple encodings with different codecs, bitrates and screen dimensions, and serve up the most appropriate format that the client device can decode. Youtube has hundreds of format variants:

The specification for AV2 has only been finalised very recently, so performant encoders have not yet been developed. Meaningful comparison to older codecs like H265 and AV1 will only be possible once that has changed. (It'll be slower, but almost certainly not one-frame-per-second slow.)

dav1d is the av1 decoder and it’s an insane feat of engineering. Written in assembly, it even eschews the normal c calling convention to get even better performance.

The normal C calling convention is really only for cross-binary calls (e.g. between shared libraries). If you're not doing that you can ignore it; it's not a weird thing to do. It would be odd to strictly follow it in assembly and I assume compilers don't either.

When AV1 was first announced, I got the impression the name was chosen partly as a pun/reference/homage to AVI, the classic but outdated format with used to be popular. Then when I saw Dav1d, OK, good way to continue the pun.

But now with AV2 and Dav2d, that completely breaks. Are we eventually going to get AV3/Dav3d and AV4/Dav4d, which will read like Ave/Daved and Ava/Davad? Seems a bit awkward. Was the idea from the start to have the 1 be the version number, and have it specifically be part of the name?

BetterThanSober

I'm pretty sure it is a homage. As for dav1d it's not a reference decoder (although partially funded by AOM iirc) so they might not know that the next iteration will simply be AV2, we have h264, h265, h266 naming though

Sorry if this sounds naive, but does it make sense to write a codec library in C/ASM considering how well Rust is progressing, especially when, as the author puts it, AV2 decoding is roughly five times more complex than AV1 decoding?

Arodex

12 hours ago

The algorithms deployed in these kind of codecs take into account not only human vision and mathematical laws of information, but also nitty-gritty details of how computers work, which are optimally exploited by directly having humans write detailed assembly rather than a compiler make a best guess and effort.

cogman10

12 hours ago

Encoder and decoder writers frequently need extremely fine grain control over SIMD instructions in order to get good performance.

The way they weave these instructions can be very hard to express with a high level language.

Further, there's a ton of work with arrays and importantly parts of arrays. They can, for example, need to extract every other element up to 1/2 the array. Unfortunately, rust has runtime array bounds checks which make writing that sort of code slower. The compiler can elade those checks, but usually only in simple cases.

The authors would be writing a bunch of unsafe rust to get the performance they want and rust makes that more painful on purpose.

I like rust, but C/ASM really is the right choice here. This is one of the few cases where rust's safety is a major detriment.

dcsommer

Performance should not be priority #1. Security should be. Why do we slow down all CPUs to prevent SPECTRE attacks yet continue to write in C? As rav1d shows, the perf loss is far less to migrate from C to Rust than it is to apply SPECTRE mitigations, and adding a sandbox around a memory-unsafe codec is going to be way more expensive again than using Rust code to start.

> Performance should not be priority #1. Security should be.

For a web browser, or a server in a bank, sure. For anything else, questionable.

> adding a sandbox around a memory-unsafe codec is going to be way more expensive

In modern world, overhead of strong sandboxes is surprisingly small. A nuclear but most reliable option is hardware assisted VM. On modern computers with SLAT and virtualized IO the overhead for most use cases is negligible. If you want something lighter weight, can use a multi-user nature of all modern OS kernels and isolate into a separate process with restricted permissions. Sandboxing overhead is approximately zero.

cogman10

> As rav1d shows

rav1d is not a full rewrite of dav1d to rust. So it really doesn't show that. It's currently C + rust + asm.

I don't think we can say anything about what this does or does not prove about the performance of safe code.

> Performance should not be priority #1. Security should be.

Entirely depends on the application. The reason rust has `unsafe` is because there's some situations where performance needs to preempt potential security problems.

dcsommer

5 hours ago

Codecs are difficult and expensive to develop. Therefore they get reused in many contexts, including security critical ones. Sandboxing is shown over and over to not be a great security solution, so what this means in practice is that security-critical software that needs software decoding get pwned because software engineers don't care to prioritize it in the first place.

Why shouldn't safety be the default? If you really want to, it wouldn't be too hard to maintain a patch on top of rustc to drop the bounds checks if you want to compile object files without them.

Software decoding has a safety culture problem, and we need to talk about it.

cogman10

4 hours ago

> Why shouldn't safety be the default?

Because safe code isn't fast enough to decode live video.

> If you really want to, it wouldn't be too hard to maintain a patch on top of rustc to drop the bounds checks if you want to compile object files without them.

Yeah, but then you are undermining safety in a critical way that does lead to security vulnerabilities (buffer overflow). And you are also now maintaining and requiring other devs for a project to use a custom version of rustc. That's certainly part of the reason that's simply not happened.

But another major part of it is that encoders end up with a lot of custom ASM regardless. That custom ASM is going to be where vulnerabilities end up. You don't really escape that by using rust.

If you are already abandoning where you critically need safety the most for performance, then why pick a language that additionally penalizes you for using unsafe constructs?

> Software decoding has a safety culture problem, and we need to talk about it.

Compilers and languages have an optimization problem that we need to talk about. SIMD optimizations remain a very hard thing for compilers to get right. We should talk about what it'd take to make compilers better and the reasons for why codec devs need to drop down to asm instead of using a high level compiler.

There might not be a solution to this problem, there are reasons for it.

jbk

Because it's 5 times more complex, you need to get the maximum performance available. Therefore more ASM than ever.

I don't know why you've been down-voted. It definitely isn't an optimal decision. A video codec isn't all assembly. There's plenty of plain unsafe C code. E.g. this is the first random file I clicked. It has a ton of raw C pointer stuff just begging to be exploited.

https://code.videolan.org/videolan/dav2d/-/blob/main/src/dat...

There is a project to write an AV1 decoder in Rust: Rav1d (really stretching the name here).

https://github.com/memorysafety/rav1d

They got within 5% of the performance of dav1d and held a contest to close the gap but I think I read somewhere that this wasn't achieved.

https://www.memorysafety.org/blog/rav1d-perf-bounty/

They claimed

> This is enough of a difference to be a problem for potential adopters, and, frankly, it just bothers us.

But in my opinion nobody actually cares about 5% in absolute terms. It's likely just Rust naysayers using that as an excuse.

I think the likely reason for dav2d using C is that they can reuse lots of code and infrastructure from dav1d. But I agree it would be much better if they worked on Rav2d instead (these names!). You can hardly complain about a 5% overhead if you're opting in to 5x more decoding complexity.

Of course any random C file is going to have pointers. Where can anything in the linked code be exploited? It seems like they're testing for bad input data with asserts to catch bugs in some functions, and properly validating bad inputs in others. Just because they're writing C doesn't mean it's vulnerable.

How can you claim nobody cares about 5%? A 5% performance increase is significant. And video decoding is not always for playback, where 5% may not matter as much.
