Project description:
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.

- delfinom 5mo agolooks at if AV2 is dead in the water https://www.sisvel.com/insights/av2-is-coming-sisvel-is-prepared/ https://www.sisvel.com/insights/av2-is-coming-sisvel-is-prep... yep
- walrus01 5mo agoSisvel is a patent troll. Take a look at the combined list of all companies that are the AOM and tell me with a straight face that all of their corporate in house counsel specializing in intellectual property law are wrong.
- asveikau 5mo agoI don't know this stuff super well but I imagine it's not necessarily about the lawyers being right or wrong so much as what they can convince people of. The ideal scenario for the patent troll is they can intimidate you into licensing with them. Another good outcome for them (though more costly) is they can convince some non-expert in court. In either case the big players behind the codec can defend themselves but a small one just picking it up downstream as OSS can't.
- walrus01 5mo agoI don't doubt for a minute that they are going to attempt to intimidate companies using av1 which are much smaller than the AOM founders.
- Telaneo 5mo agoThey've done the same thing with AV1, and I can't see that having prevented adoption, nor can I imagine Sisvel wanting to poke the bear that is AOMedia unless they're certain their case is absolutely watertight.
- walrus01 5mo agoI see zero public evidence that they've filed any lawsuits against the members of AOM in any jurisdiction. I'm sure there's been a lot of threatening letters sent...
- Telaneo 5mo agoSame, which is what makes it seem to me that that case is absolutely not watertight. Those patents are probably all about esoteric minutiae (to be fair, that's because that's what it takes to make a better video codec these days) and everything and anything that can seemingly be connected to AV2 (or AV1 for that matter), many of which have only gotten a patent because the person approving it only barely understands what it's saying.
- jorvi 5mo agoYup. The Dolby/Disney vs Snapchat lawsuit is going to be the first one. So far it's only been filed. 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.
- dmitrygr 5mo agoI would love to live in a world where this happens. I will place big bets that it will, regrettably not happen.

- ronsor 5mo agoThis is a thinly veiled extortion racket and any competent system would fine them into bankruptcy.
- mort96 5mo agoWe need a more efficient way to eliminate bullshit patents or bullshit patent infringement claims than "violate them then spend millions on lawyers to fight them in court".
- brookst 5mo agoSure, and at the same time we need a more efficient way to ensure big companies can’t just take what they want and bury anyone who complains. It’s not an easy problem.
- voakbasda 5mo agoStop big companies from ever forming. They are not a natural force that cannot be reckoned with. We allow them to exist. Revoke the charters of any business over 500 employees.
- pmontra 5mo agoI can see a number of ways to work around that limitation, without even lobbying and bribing. And I'm not even a lawyer or an accountant. Eventually all the money and power will converge in a few sub 500, or sub 50, companies and nothing will change.
- extraduder_ire 5mo agoDoes that happen in places like Europe, where software patents aren't a thing?
- account42 5mo agoRight now we have neither so working on one can't make the other worse.
- BLKNSLVR 5mo agoYou can tell Sisvel are a bunch of grifters by the fact they use slight grey text on a slightly less grey background. 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.
- astrange 5mo ago> If AV2 was vibe coded, there would be no case. …for copyright. Not for anything else. Patents would still apply.
- shmerl 5mo agoTrolls will always be trolls. The need to fight them just shows the need to reform the garbage patent system to make sure no one can ever patent software.
- hulitu 5mo ago> AV2 is the next-generation video coding specification from the Alliance for Open Media Oh no. Not another one. I presume this one makes lossy better, or faster or both.
- Dylan16807 5mo agoWhy do you not want another one? We're approaching a decade since AV1 released. There's plenty of improvement to put into a new format.
- hulitu 4mo ago> There's plenty of improvement to put into a new format Like what ? Lossy compression has nothing to offer since about 10 years ago. Is there a flac for video ? Is there a codec able to "guarantee" DVD quality on today's internet ? Those "up to" really sound like "up your's".
- Dylan16807 4mo ago> Like what ? Lossy compression has nothing to offer since about 10 years ago. h.266 is about 1/3 smaller than AV1, so it fits about 50% more video per megabyte at the same quality. AV2 will almost certainly be better than h.266 > Is there a flac for video ? ProRes is a close equivalent. > Is there a codec able to "guarantee" DVD quality on today's internet ? Those "up to" really sound like "up your's". Basically no. You won't find a video distribution codec that guarantees any level of quality because they're all configurable. And youtube in particular is always tweaking the quality dial as low as they can. But if you can get a bitrate that would be passable with h.264, then AV1 will look good and AV2 will look great at the same bitrate. And they can all beat a DVD with a fraction of the bitrate. You just have to not get greedy.
- wolfi1 5mo agois there already an av2 encoder for ffmpeg?
- jbk 5mo agoNo, since the format is not final.
- simlevesque 5mo agoThen how can there be a decoder if it's not final ?
- adgjlsfhk1 5mo agoit's a decoder of the current draft
- dylan604 5mo agoYou seem to be unfamiliar with the concepts of alpha and beta or other pre-release software. Seems a strange thing to be unfamiliar though in 2026
- saratogacx 5mo agoIf you see the state of what is called "production quality" software these days, alpha/beta quality has lost most of its meaning. You now just wait for "next prod" // I jest... but only to hide the sadness
- Dylan16807 5mo agoNo, they're pointing out how the logic they're replying to is flawed. If there can be a decoder, there can be an encoder.
- BoingBoomTschak 5mo agoThe bitstream could be "final" without the coding tools being so.
- dirasieb 5mo agoi don't even own a dgpu capable of encoding av1 and they're already coming out with av2?
- dylan604 5mo agoIf the thing you are working on is already out of date to the point there is already significant work on the 2 version, why would you continue?
