I don't even use av1 for anything. 🤷

[–] commander@lemmy.world 18 points 5 months ago (1 children)

Streaming sites use them so there's a solid chance you've used it plenty without actively choosing to

[–] pastermil@sh.itjust.works 10 points 5 months ago (1 children)

Booo....

AV1 + OPUS for life!

[–] MHLoppy@fedia.io 6 points 5 months ago (1 children)

What about AV2 + Opus though!?

[–] pastermil@sh.itjust.works 4 points 5 months ago (2 children)

It's not even out yet...

[–] MHLoppy@fedia.io 4 points 5 months ago (1 children)

"for life" covers that eventuality :P

[–] pastermil@sh.itjust.works 2 points 5 months ago

We'll see. I'm hoping I won't have to replace my vast collection of AV1 encoded series as I had with H264 & H265.

[–] ms_lane@lemmy.world 3 points 5 months ago (1 children)

No Raspi support for AV1 either. I'm stuck in patent hell HEVC land.

[–] pastermil@sh.itjust.works 1 points 5 months ago

There's always the CPU decoding.

[–] just_another_person@lemmy.world 7 points 5 months ago (2 children)

Honestly, that's how the codec game works. Most people or software don't adopt until after the successor is in place. It's more about the software side lagging to adopt though. Nvidia just got AV1 into their hardware processing pipeline in the last 2 years. I think AMD is even more recent than that.

[–] bruhduh@lemmy.world 4 points 5 months ago (1 children)

Surprisingly enough first to adopt av1 into GPU was intel with arc GPUs

[–] just_another_person@lemmy.world 3 points 5 months ago

Intel was one of the funding corporations for that initial APM codec work, so that's not shocking at all.

[–] chillpanzee@lemmy.ml 3 points 5 months ago

that’s how the codec game works.

That, and add some patent pools filled with dubious claims of essentiality, sales deals made under the threat of litigation, and ever-present claims of "twice as efficient it's predecessor" with a big asterisk. Fun times.

[–] ABetterTomorrow@sh.itjust.works 2 points 5 months ago (1 children)

Pft AV7 is where it’s at.

[–] ms_lane@lemmy.world 3 points 5 months ago (1 children)

Look at those sleek lines, it all interlocks.

AV7 is clearly the best.

Av7 - oh god imagine if you pulled that seven in a bit. Sexy.

[–] ABetterTomorrow@sh.itjust.works 1 points 5 months ago

Oh shoot, you’re onto something there! Ah you got me thinking about graphic design now! Good eye though ;)

Why do we need more codecs? Technical progress is nice but unless the new thing is literally 5x better than the old thing, media codecs are for practical purposes a solved problem by now. Slight improvements aren't worth the churn and patent hazards.

[–] UnfortunateShort@lemmy.world 15 points 5 months ago (1 children)

AV2 provides enhanced support for AR/VR applications, split-screen delivery of multiple programs, improved handling of screen content, and an ability to operate over a wider visual quality range.

[–] solrize@lemmy.ml 1 points 5 months ago

Thanks, that sounds mostly like container features. Maybe that helps.

[–] __siru__@discuss.tchncs.de 8 points 5 months ago (2 children)

Isn't AV1 patent free?

[–] ABetterTomorrow@sh.itjust.works 2 points 5 months ago* (last edited 5 months ago)

Yes and no. Hardware = pay google - Proprietary software = pay google or 3rd party - Open source (d@v1d) = free (this is what most people use = VLC Player)

[–] solrize@lemmy.ml 1 points 5 months ago* (last edited 5 months ago) (2 children)

I don't know, but if it is, why take chances with yet another codec? The hazard is less about the developers asserting patents than trolls coming out of the woodwork after the codec is deployed.

[–] ftbd@feddit.org 4 points 5 months ago

Imagine living in a place where software patents exist

[–] Waryle@jlai.lu 2 points 5 months ago* (last edited 5 months ago) (1 children)

AV1 and AV2 are both patent free and nobody will be able to grab them to be a patent troll, that’s the point. Maybe you should start educating yourself a bit on the subject before ranting?

[–] solrize@lemmy.ml 3 points 5 months ago (1 children)

Patent troll = someone pops up claiming av1 or av2 infringes on some obscure patent that they control. That happens all the time. There's no way to guarantee that it won't happen with any codec or really with anything. It is very expensive to defend against even when the claim is bogus.

[–] Waryle@jlai.lu 4 points 5 months ago* (last edited 5 months ago)

That happens all the time. There’s no way to guarantee that it won’t happen with any codec or really with anything.

Yes, so there's no reason to hold back on releasing updates, since it could very well happen on AV1.

It is very expensive to defend against even when the claim is bogus.

The principle behind AV1, once again, is to have a modern codec that is out of reach from patent trolls. Those who are part of the AOM consortium, which developed this codec, have all contractually agreed to unconditionally license all patents they hold that are necessary for the implementation of the codec.

And those who are not part of the consortium and who would like to claim patents relating to the AV1 or AV2 codecs would have to face the legal teams of the companies part of said consortium, including Amazon, Alibaba, Adobe, AMD, Cisco, Google, Intel, Microsoft, Mozilla Foundation, ARM, Huawei, Samsung, Tencent, Meta, Nvidia, Apple, Netflix, and other large companies.

The AV1 and AV2 codecs, after perhaps H264, are the most secure codecs available today in terms of patent trolls. Nobody has both the will and the means to attack it.
