Chrome 85 can now view .AVIF files. Microsoft Edge 85 cannot view .AVIF files which is a little strange as they both use chromium, i guess microsoft decided not to adopt that functionality right away.

Nice, flipping that right now! Looking at the bug history (particularly #1625363 (https://bugzilla.mozilla.org/show_bug.cgi?id=1625363)), it looks like turning it on by default was held up first because they wanted to switch to dav1d, and now because they're overhauling the entire media handling stack and it's sort of in limbo until that's done. At least there's an easy way to test it out, though.

Nvidia confirms AV1 hardware decoding on Ampere GPUs.

Stream and playback videos at 8K HDR using the new AV1 decoder on GeForce RTX 30 Series GPUs, which enables more efficient playback of 8K HDR YouTube videos. With much more efficient compression than H.265, AV1 dramatically lowers the internet bandwidth requirements you need to stream high resolution video.

Good news for AV1 in general having AV1 support from Intel and Nvidia in their next gen GPUs. Only AMD is missing, we have to wait for RNDA2 if it supports AV1 as well.

This is a big deal!

AMD does typically lag NVidia for a year or more in video capabilities, so I wouldn't make any assumptions about their next gen before they announce something.

At this point, it's really Qualcomm and AMD needed. Although given the much slower replacement rate of PCs these days, it'll still be at least a decade before it'll be safe to assume all PCs would have HW AV1 decode. IIRC, it was around 2012 before it was quite rare to have a PC without HW H.264.

Intel has launched Tiger Lake CPUs.
Intel and NVidia down. AMD to go.

And everything supported 10-bit decode that I know of, so we may finally have a codec that can be 10-bit always (although SW decoders are still somewhat slower with 10-bit).

Didn't Samsung throw their hat in with AV1 awhile ago now?

They usually announce their next Exynos flagship SoC around the end of the year, so we might see some action with them too.

The COVID business slowdown seems to have impacted the production timeline of Rockchip RK3588 and perhaps the Amlogic S908X which also have AV1, but I think that there are at least weaker S905X4 chips in the wild with AV1 capabilities too.

I'm still holding out hope that the newly awaited "Sabrina" Android TV dongle from Google will use S905X4, despite early claims it uses the older S905X2.

Pretty sure it uses the S905Y2 which doesn't even have ethernet.

An interesting slide from nVidia.

Using latest Chrome M85 and YouTube 8K HDR 60fps AV1 content, a Core i9 9900K managed to decode in SW only 28fps with a 85% CPU utilization whereas an Ampere AV1 HW decoder manages real-time performance of 60fps without bothering CPU at only 4% utilization.

The only thing missing is the HW decoder's utilization during the achievement.

No surprises there. 8kp60 AV1 decode is absolutely punishing, especially considering the mention of HDR which means 10 bit...

It's extremely impressive that the new RTX 30 series will handle it in hardware!

And for premium content licensed with HW DRM requirements. AV1 would be useful for YouTube and Twitch way before premium services. Particularly as most premium playback devices already have HEVC, but YouTube and Twitch are mainly watched in browsers, which are mainly Chrome and Firefox, and only have H.264 as a baseline.

Hello,

Just a very quick message to let you know that I finally could have an answer from a AOMedia founding member company, and I thank them very much for their time, and so no surprise, they confirmed me that NHW is not of consideration/interest for AOMedia.NHW could have been a tool for AV1/AV2, but the tools quality is evaluated with PSNR and SSIM curves, and NHW has very too bad PSNR and SSIM results -but again despite this, I still find that it is visually more pleasant because it has more neatness...-.

So NHW will definitely stay a hobby (will have to slow down my work on it in the next months), but if you found time to take a look at NHW and if you would have advice/suggestion about it, do not hesitate to post it on the NHW thread, or send me an email.

Cheers,
Raphael

AV1-decoding with RTX 3080 compared to GTX 1080 and RTX 2070: https://youtu.be/lTRbLnWdqwk

16th September 2020, 16:28

How smart to compare HW decoding of AV1 using 3080 to CPU AV1 decoding using 1080 and 2070 Super which the video subtitles say it's a 2080 card.
And HW AV1 decoding is not using NVENC that this incompetent guy thinks.
It's using NVDEC.
The NVENC part (HW encoding) of Ampere cards is identical to Turing cards.
The only thing useful of this generally useless clip is that YouTube's AV1 8K60fps clips utilize about 47% to 54% of AV1 HW decoder of Ampere card which I think is impressive and a metric for AV1 HW decoder of Tigerlake Xe GPU and AMD RX 6000 series to beat.

Benchmark seems legit even if they don't know the lingo. Damn, the 3080 is one hot, power-hungry card. Hopefully it'll be optimized in drivers eventually. No need to buy 3080, I'm sure they are going to release 3060 and possibly 3050 card.
And there is also Xe from Intel.
Personally, I'm going to wait for a budget RDNA2 card hoping for at least 4K 10bit AV1 acceleration or even better (like 8K60fps)

I'm a bit curious to what you are referring to?

From what I've seen, yes the power draw is high under load, but efficiency is rather good for an top of the line card, although its not that impressive for an die shrink generation, and both stock cooler and third party seems to keep it under 80 degrees at rather low noise levels.

It's a bit of a shame that CUDA for GPGPU and Nvenc is so superior (at least at an software support level), havnt been able to consider an AMD card for years.

It's a bit of a shame that CUDA for GPGPU and Nvenc is so superior (at least at an software support level), havnt been able to consider an AMD card for years. nVidia managed to sabotage OpenCL leveraging nVidia's Vice President who is also the President of Khronos group, which is in charge of OpenCL.
He literally butchered the latest version of OpenCL in order to make CUDA the single greatest GPGPU API.
But all these are just malpractice and market manipulation very well known to be handled by the leather-jacket-man.
Regarding HW encoding SW, I could easily say that VCEEnc app for AMD cards is on par with NVEnc and QSVEnc for nVidia and Intel.
But I was referring to AV1 HW decoding here, which all of the modern GPUs support.
And Ampere's HW encoding is exactly the same like Turing.
They didn't change it.

True. Still, NUCs are pretty well made, and offer 100% Intel hardware and drivers. Depending on the application this can be very preferable to a laptop. The integrated display, keyboard, mouse, and battery of a laptop can also be preferable in certain cases ;)
Not only that, cheap laptops does not come with great io like this (especially Thunderbolt), and the sku:s with the higher end igpu.

Tbh were i live nuc have always offered rather good value tbh, i got a kaby lake one on release, I dont even think there were any laptops with hdmi 2.0 port at that point, which was pretty much a must for that machine.

Nuc is a nice concept, but ultimately a failed one, because they didn't push it hard enough. I'm surprised they even continue making these. The volumes are low and Intel isn't a motherboard/bios manufacturer...

https://www.computerbase.de/2020-09/intel-tiger-lake-test/2/#abschnitt_av1beschleunigung

They might have used the launch review driver which is older than the public driver but supports AV1 for some reason. Or it could have been a specific Google Chrome/VLC issue, PC World didn't use Chrome/VLC. But of course may be Computerbase did something wrong, not sure.

What's the die size of an AV1 hardware decoder?
I've not seen any hard numbers, but from what I've heard from insiders, it's relatively quite large. Bigger than estimates for VVC's decoders, and quite a bit bigger than HEVC and likely EVC.

This is a probable driver for why HW AV1 decode has been slow coming for mobile devices. Until it's in the Qualcomm 400 series SoC, it won't be on track for becoming universal.

Hopefully someone here has more specifics.
