Echoing Geoff's article, I'm a big fan of the 51nb mobos from the X62 on. The X62 was very very good, and the T70 and X210 are even better. Can't wait for the X63. One reason I'm taking time off from making X62 backligh

Ha, many people have asked for that :-) I jokingly suggested we should go get some VC and launch a plugin company...

Because Jarek is frankly out of line, and I see no reason to sugarcoat it. Google pissed him off (and I'm sure he has reason to be pissed) but he's not exactly being truthful about what happened, or what is happening. Being angry

Put it in AV1 and it doesn't. The entropy coder in AV1 right now is Daala_EC. It's the entropy coder because we measured it directly against rANS and the other candidate encoders and it performed the best. Hell, you can check out

Not useless, just not as good as Jarek liked to claim. It's a neat technique but hardly a breakthrough. In the end, for AV1, Daala_EC was better. As for 'needed a defensive patent', need is the wrong word. In the current pat

The answers aren't entirely separable. Hardware capable of any kind of video wasn't accessible to the larger community and it sure as hell wasn't affordable . When Xiph.Org started (1994), even audio required high-end hardw

I would too. We'll see what the future holds.

Yes. We still have internal investment is many pieces of Daala that didn't get adopted in AV1. I don't know the liklihood that Daala will rise again as a standalone codec project... possible, wouldn't bet on it.

The next two will be on the Constrained Directional Enhancement Filter and the Daala Entropy Coder, which AV1 adopted as it EC system. Beyond that, there will be several more though I've not yet planned out a specific order.

Luc Trudeau, who wrote most of the deeper technical papers and specifications on CfL at Xiph, has a real gift too. I'm riding his technical prose in this post. If you liked my update, you'll like his papers linked in 'Addi

> Would AV1 have been possible in 1993 when MPEG-1 came out? No. There weren't enough transistors in the world. I'm not being silly. Something like Av1 happens now because Moore/Dennard allow it to.

MPEG is, for purposes of this discussion, a system that member companies have learned how to game. It is so thoroughly gamed that it has become dysfunctional and an impediment to progress. The open/RF development strategy is now cons

I collect vintage headphones, and especially relish the truly absurd ones I can't believe anyone thought were a saleable item. I'm up to about 300 different models.

I will not repost the entire thing here, as there's a few naughty words born of frustration, and this might well be a family forum for all I know. My take: https://xiphmont.dreamwidth.org/84214.html

The patent does not cover rANS. rANS has been independently discovered a few times at this point. The patent filing covers Google's use of it.

I blogged about this elsewhere. From reading the filing, Google is not patenting his work. They're patenting their specific application of it, and the claims seem to me fairly tightly tailored to AV1.

Indeed (have some of those too), but I assumed we'd artificially limited ourselves to talking about i7. I'm not sure why I assumed that, because you're right of course.
