Yeah, no production or large scale VC system is running software AV1 encoders on smartphones. You will drain a full phone battery in 1-2 hours of calls. It just doesn’t make sense and will result in extraordinary power/battery drainage at best, or output that’s worse than hardware encoding. The only way you could get AV1 to software encode in realtime AND low latency on a mid-range Android chip is by disabling or ski…

So, status remains quo, the commons remain tragic, and glory to H.264 forever?

At least until a better codec has widespread enough hardware support, I think.

Based on AV1's trajectory, hardware encode isn't necessary (though it is nice). The current encoder is a reference encoder. Now that the spec is finalized, expect significant speed improvements from production encoders (realtime likely won't happen until we get it in hardware though)

Hardware encode is required if you want things like video calls, camera recording and such to use it. It isn’t required for content distribution platforms which aren’t realtime and the cost of encode is easily made up by hundreds of thousands of streams.

A few things - this is one step in a long, LONG path. AV2 is currently unusable in its current state (the encoder typically runs at around 1fps on good hardware), and likely will remain so til ~2028 when the first av2 hardware accelerated chips start dropping. Even then, I wouldn't expect AV2 streams to be common til 2030. IMO, if it were just the efficiency gains on the table (which are substantial - ~20-30% over AV…

What I'm interested in is seeing how this will improve the AVIF image format. AVIF stomps the competition for low-bitrate still images (where chroma subsampling is used). For lossless images, not so much. Lossless JPEG XL and lossless WEBP make lossless AVIF look like a joke.

That's fine and not anything new for codecs, they always take a long time before mass adoption. Take a look at AV1 itself, you can't even say it's really ubiquitous on all hardware. It's quite well along in adoption compared to early days, but some mobile devices are still lacking hardware acceleration for it.

It is still ironic to me that my Steam Deck has decode AV1 acceleration, on a really old CPU/GPU combo.

AMD added AV1 encoding only in later SoCs though. Next Steam Deck will have both.

Hopefully their patents will be busted and preferably Dolby will be also forced to pay damages for filing invalid lawsuits. That's the only way to teach patent trolls proper lessons.

While I agree with the general sentiment, I would not classify Dolby as a "patent troll" — they still do invest in research and developing products, right?

I'd classify any patent racketeer as a troll. Dolby has nothing to do with AV1, they just want a parasitic rent on it. Whether the troll actually does anything else besides the trolling part isn't really relevant.

How is Dolby a patent troll? :D

Because they have nothing to do with AV1, they simply want to leech on it. It's fitting to call them a patent troll.
