Yes, hardware support is disappointing.
IIRC for HEVC the Samsung and LG TVs were the first to have hardware decoding in late 2013/early 2014 after HEVC approval by ITU in April 2013. Now AV1 finalization was in June 2018 and still no hardware in sight, really. Intel probably Tiger Lake Q2 2020 at the earliest. Nvidia with Ampere also 2020? Nothing from Qualcomm. Looks like they all started working on it pretty late. |

What do you mean?
Majority of new devices has VP9 support now.

That would indicate a trend towards AV1 decode launching in high end chipsets first, and taking longer to get into lower-cost handsets. |

The make or break is how many extra mm^2 the decoder takes. |

* Next year we will starting see some high end CPU/GPU with AV1 HW decode support. * In 2021 HW decode for low end CPU/GPU and encode for high end CPU/GPU. (some TVs, consoles) * And in 2022 for all cpu/gpu. (All modern TVs, consoles) Note: The first HW with encoding support will have bad quality comparing with software. They have to mature over the years. And if you are asking, all the nextgen consoles that will release next year will not have AV1 HW decode support (because they release with a cpu of this year).

Also some two detail from Google Stadia: At launch they will use VP9 hardware encoding and somewhere in the future they will switch to AV1, but only when hardware encoding is available.15:19 for VP9, 22:53 for AV1, 31:45 for hardware video encoders. |

IIRC PVQ was less complex so easier to realize by hw, but was decided against, because of needed additional development time, even though it would've increased efficiency, too. We'll know when gen2 will be realized (in 5 or 10 years) hehe |

https://blog.embed.ly/what-twitter-i...s-e1b74068cebd https://rigor.com/blog/optimizing-an...th-html5-video they do it for reduced memory footprint, pause/play, reduced size, better caching, hw decoding, partial decoding, fast first playthrough, higher possible bit depth for animations etc. EDIT: for regular pictures it needs to be an image format people can download and share https://www.cnet.com/news/facebook-t...-users-squawk/ hevc in ISOBMFF (heic/heif) might turn out a good solution if windows users don't need to add support manually through the microsoft store and android switches to it. then whatsapp could switch to it as well (with transcoding back to jpeg for older devices) EDIT2: at least Firefox finally added WEBp support (including animations) so it counts as an alternative (especially when they update their internal codec again) https://hacks.mozilla.org/2019/01/fi...r-new-tooling/ Last edited by Djfe; 10th May 2019 at 10:55. |

AV1 is now quickly becoming mainstream, is it time for an separate Sub-Forum for AV1 (or AOM codecs in general)? I would love separate threads for aom, dav1d, rav1e, svt-av1, hardware acceleration and applications that support AV1.

My vote is it's too early for that. It's nice reading about the encoder and decoder stuff in one place for now. Or put another way .. at what average messages/day rate should it split Maybe 25? Where well short of that now.

I think the number of messages per day is now also limited because small things don't seem important enough for a combined thread. With split threads I would report way more often about small changes in dav1d performance, SVT-AV1's troubles with Open Source and rav1e and aom related news. Now it just doesn't seem important enough to report on in a general thread.
For example:

A thought I had, was to make splitting up the general thread easier, you could just take everything pre-bitstream freeze and label it as such.
Thats got to be a serious portion of the thread, and mostly about AV1 development? Last edited by soresu; 15th May 2019 at 16:04. |

Facebook appear to have it all hooked up to deploy AV1 since about a year ago, but whether they actually use it for anything other than testing yet I don't know. Anyone use Facebook to watch popular videos? Do they have a "stats for nerds" equivalent? |

The latest report from Facebook shows 92% of its users are on Mobile Apps. That is up from 90% YoY and trending towards 100%. I doubt they would want to push AV1 for the sake of saving bandwidth ( even less than a rounding error for Facebook ) at the expense of user battery. ( Which will lower user engagement time, and lower ads revenue, everything Facebook is valued of ) |

Amphion announced the CS8142 (PDF), the first AV1 hardware decoder!
SVT-AV1 just opened a huge PR with unit tests: #260. They also have a lot of development branches open, including one with a lot of AVX2 and AVX512 optimizations. |
