And it is hasn't pass IP test, I can bet the bitstream wont be frozen until next year. It is good they didn't rush it. But another year for HEVC to gain.

Let's just hope Apple hold off HEVC for another year.

No-one is adopting h265. Only broadcast and ultra hd bluray are using it. Almost no digital cameras record in h265 even though there have been hardware encoders for years for mobile devices. AV1 shall be the king for many years on the web. We really could do with safari adding support for vp9 though in the meantime.

Well... that's not really true. All the major OTT streaming providers are doing 4k using HEVC. It's a big deal to high end consumers because it enables HDR!

enabling HDR hasn't so heavy requirements at all most of the HDR requirements are rather on a higher level like when to enable HDR and when not if detected that it is HDR content, it's more the clean management of it inside the Device architecture.
Hollywood has higher requirements hence they want foremost artistic control of it to manipulate it to their liking to get certain emotional feedback from the viewer from it.

That's also why it was rather Simple for Samsung to adapt their Tizen Software/Hardware stack to support it fast for VP9, the most complex thing in HDR is how efficient it works together with the PQ and how clean it is percepted in the end from the output Device and the acquisition of it

??? broadcasts, discs and streaming services like Netflix and Vudu are using HEVC for UHD (HDR)

Actually I don't get why we need yet another codec, VP9 is brand new and it's just starting to be supported on hardware. VP9 Profile 2 (10/12 bit + HDR) is even newer

AV1 seems to be late to the party IMO

VP9 is quite a bit worse than HEVC, so compression improvements are welcome.

Can somebody provide me 480p, 720p and 1080p AV1 video samples? I can't find any on the internet. Thanks in advance.

Well, currently AV1 bitstream changes daily and depends on the experiments you enable in the encoder. So what do you want to do with them?

I just want to test how well it plays on my hardware.

HEVC started development before VP9 though.

You aren't going to learn much that's useful yet about how a final version would work on your hardware, or would work on then-current hardware when it's released.

New current link to aom codecs. Authors every month change the location of the link on the github. I also see that this year the project was abandoned ffmpeg-Daala.

New Java Web AV1 Bitstream Analyzer

Trends to Watch at NAB 2017
http://www.studiodaily.com/2017/03/f...h-at-nab-2017/
AV1 is scheduled to be finalized in Q4 2017, meaning a solid preview of its capabilities should be on display at NAB.
Everything is cool, but at present I don't see the use of hevc or av1 codecs in the cameras. Nor do I know what is meant by new camera HDR. After all, there are cameras with S-log3 or other color matrix settings.

Jesus F. Christ - the developers are making private clones on github to work on the code (and for other developers to see the changes). It is better to avoid any of this as developers update with main repository when they need to and who knows what experimental modification they performed. If you want to check AV1 you always need to get the code from the AV1 main repository. This code was reviewed and is always the most up-to-date.

No wonder as all the work shifted to AV1 and daala won't be finished..

LAVvideo decoder doesn't play AOM codecs. Even after registration with Windows 10. I mean 10bit movies.

Maybe crap, but someone reads and improves in the next version.
