They filed a suit, henceforth making a claim of an issue...... They haven't "proved" anything other then they have lawyers on staff that can file some paperwork until the suit is settled in court...

How does that prove anything?

They're claiming that there are patents, but that doesn't mean there are.

No codec can ever avoid patent-pool claims.

Every single AV2 news here in the last week has seen exactly the same question.

Either go back read the answers there first, or I will assume you are part of a FUD campaign (yes, I know HN guidelines, but again every single AV2 news in the last week has seen the same rhetorical "questions" as top "comments").

Smaller files but harder to decode

AV2 saves 25% bandwidth at the cost of 5x more decoding complexity.

I understood it as compression is 25% better : a quality of 10mbps in av1 can be achieved with 8mbps in Av2. But, it needs 5 times more compute power for this 25% gain.

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

Yes, this is going to be fun to watch.

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

Rust does not bring more performance. Just more safety.

Go ask FFmpeg what they're writing their encoders and decoders in.

Yes? There is 5x more code to optimize the ASM for.

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.

Return of the 8MB Shrek encodes?

Norbert Wiener in the 1940s. He invented the technique.

It's a semi-common last name.
