How does that prove anything? They're claiming that there are patents, but that doesn't mean there are.

Dolby is only the most recent case, Sisvel consorsium actually bills licences per device: Consumer Display Device: EUR 0.32 Consumer Non-Display Device: EUR 0.11 (source here: https://www.sisvel.com/licensing-programmes/audio-and-video-... )

That crowd are just deeply concerned one of their lucrative revenue streams is disappearing.

So they seem to be attempting to pull a fast one and use unproven claims to try and convert their competitor into a replacement revenue source.

It'll probably be a case of whoever has the best lawyers + contacts + persistence wins.

But it'll be interesting if discovery shows evidence they know they don't have a case and are trying it anyway. "Piercing the corporate veil" can theoretically be a consequence of that AFAIK.

I came to post this as well. Until widespread, inexpensive hardware catches up to a 2018 codec, AV# will remain a niche ideal.

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 cli…

Yeah I could imagine the AV1 codec sticking around for a very long while, even as a fallback for AV2. There's still hundreds of millions of people out there using old/cheap devices (especially in developing countries) where that battery drain from software decoding is a big problem, so AV2 would be nonviable.

> I'm not sure what these two lines mean or if we can compare them, any help? AV2 saves 25% bandwidth at the cost of 5x more decoding complexity.

What does "complexity" mean here? Computation required?

Yes, much higher computation required to encode it, and decode it, both.

Return of the 8MB Shrek encodes?

https://web.archive.org/web/20210416200451/https://cdn.disco... Shrek 1 at 8.34MB including audio.. insane

Video resolution: 128x72, hahah. Late 90s RealPlayer postage stamp video is back! To its credit, that whole movie is probably smaller than RealPlayer itself was.

I love this, hope to see a AV2 version at 8MB

1dav2codecs? 2av2furious?

And then AV3: Tokyo Drift, and after that AV Episode 1.

Already predicting which versions to avoid, huh.

This seems like an interesting case to test AI agents on.

Like we had weird examples like C compilers and Bun. This is a much more interesting example because its highly nontrivial.

AV1 exists, Dav1d exists. Lets see AI take the AV2 spec and Dav1d code and try to make a working high performance AV2 decoder.

'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.
