10th gen Intel CPUs don't support HW accelerated anything in regard to AV1.

AV1 decode takes a lot of transistors, which are expensive. Are consumers willing to pay an extra $5-10 for a phone with AV1?

AV1 really didn't get anywhere near the kind of tweaking and tuning needed to make for efficient HW and SoC decoders like the MPEG codecs have. I'd expect AV2 to be a lot better in this regard. But VVC will provide better compression efficiency than AV1, with less of an incremental cost increase than AV1. Even if VVC costs $1 a unit in codec licensing, it likely would still be cheaper to a SoC vendor than AV1.

Plus Qualcomm spent all those resources on VP8/9 to never see it being used meaningfully outside of YouTube, and not providing any customer benefit beyond what H.264 already delivered.

Eh? Wasn't AMD and nVidia involved in AV1 development + several mobile SoC developers?

From that alone it would seem AV1 had more input from actual hardware vendors vs a theoretical hardware/transistor cost in MPEG development schemes as I've never heard of hardware vendors being involved previously.

Of course time itself was a significant constraint on AV1 development.

Honestly noone really expected wide-spread hardware deployment before middle/end of this year. That one SoC already has it and another doesn't seems perfectly normal to me. Adoption takes time, SoC development cycles take years. Something that is available today would've planned to include AV1 over a year ago.

People were also ranting that VP9 is even worse for hardware implementation
Lo and behold, Youtube started using it and every cheap chinese SOC managed to implement it

Still very much hoping for hardware decode.

This definitely can't be seen as anything other than a major blow towards AV1 adoption. If the latest Qualcomm SoC doesn't support it, why should anyone else care? :|

Maybe next gen? But I mean.. The bitstream spec has been out for years. I know there was an eratta that kind of reset the clock not that long ago but.... yikes.

If I was all-in on AV1 I'd be very nervous right about now. HEVC is delivering great results today, and LC-EVC and VVC both look quite promising in the near future, and hardware support is completely guaranteed for VVC.

just wait for nvidia this year.

and microsoft has to do there part too.

it took 19 month to get VP9 hardware decoding on maxwell the decoder was just not accessible just to show how this worked and there was no word about it too the card where just able to do that from one driver to another and the windows update 19 month after it release date...

BTW that 3 years after VP9 was released.

i don't see a reason to get nervous.
in the end it doesn't matter if youtube and/or what ever are forcing this type of content the hardware decoder will follow.

Intels upcoming Xe architecture presumably supports 12 Bit AV1 according to a new leak: https://videocardz.com/newz/exclusiv...-0-xe-graphics




RKl-S will use the smaller GT1 from Intels Gen12LP.

Now THAT is some good news (Intel). Even if it's decode only.

@benwaggoner I can't help you with compiling but in case it may be useful here are the Windows builds most of us are using over at AV1 Discord : https://jeremylee.sh/bin.html

SIMD optimisations for 10+ bpc content on x86 are still completely missing, you might get better performance on a recent W10 on ARM laptop due to the NEON optimisations for ARM64 added more recently.

With 8 bpc content though both the ARM64 and x86 platforms are mostly done now for SIMD optimisation (excepting AVX512), I would not expect any dramatic speedups for that now without adding more cores.

I'd be surprised to see material perf improvements by adding AVX512, at least on current gen CPUs, due to aggressive thermal throttling.

This will hopefully change over time, just like we saw AVX2 become much more useful in the second major generation of implementations.

Unfortunately you still can't search/skip the svt-av1 stream quickly if you use the default value --irefresh-type 1 (CRA; Open GOP).

Since there is no hint if it is a svt-av1 encoder or dav1d decoder problem, I tested the latest version.

Does anyone have a hint?

How did you mux the file? The problem suggests that the muxer did not mark the keyframes in the container index.
