    That doesn't answer the question. Daala is significantly different from AV1 overall, to be worth continuing developing it on its own. But Mozilla hit some technical roadblock they didn't manage to solve at that moment. Now looks like active development has stopped.

    Daala wasn't fully merged into AV1, only some parts of it. Its core idea of using lapped transforms was not for instance.

      To be fair to Mr. Octus, both Youtube and Android are "within company with the hardware to encode it" (ie. Alphabet nee Google).

        Interesting primer on how to optimize AV1 using AVX2.

        After rewriting, we noticed the following speedups:
        • 240p: 1%–5% depending on mode. As this is the lowest resolution, the DSP routines take a small amount of time relative to other things.
        • 480p: Similar to the previous case; up to 7% sometimes.
        • 720p: 5%–15% depending on mode. Speedup increased as DSP became more important in terms of time.
        • 1080p: Very similar to 720p.
        We chose a real-life task – improving the speed of an open source AV1 codec using vector extensions and comparing the performance increase results.

          AV1 better take the time it needs to get things right, because the stars will never align like this again. It doesn't matter if we wait a generation of devices for harware decoding if the codec is defective. Once hardware decoders start landing that is it, thats the AV1 we are stuck with.

            I wonder why they dropped the Daala transforms (daala_tx). Was it simply too late? Maybe they can reconsider for AV2.

                I understand what you're saying, and while Google and Netflix make-up most of the stream video on the web very few other sites are using vp9. Some are using vp8 but compared to h264 (which was developed in what, the early 2000?) it has not gained traction at all despite a giant like Google behind it.

                Competitors of YouTube are using h264 (Vimeo, DailyMotion)
                Live stream services are using h264 (Twitch, Picarto)
                Independent video providers are using h264 (VRV, Kanopy, Mondo, MUBI, etc..)
                Direct Content Providers are using h264 (NBC, ABC, Fox, Turner, A&E, HBO, etc..)
                Government websites are using h264 (In the USA at least, which is sad...)
                YouTube might server vp9 but I'm fairly certain that 99.9999% of uploaders are using h264 or carelessly uploading badly optimized mov, wav, etc...

                I should have been more specific, it hasn't gain traction with the majority of "average users" or smaller non-mega giants like Google & Netflix. So everyone else

                  Aw yeah, throw some more wasted time down the pipe. The next codec noone will ever use besides a few FLOSS zealots. Is xiph.org good for... anything? All the codecs that are actually in use (FLAC, VPn, Opus) are outside jobs moved into the Umbrella afterwards lol.

                    Vimeo will be using VP9: https://vimeo.com/blog/post/luminous...ty-hdr-arrived

                    Twitch will be using AV1 because of its advantages in low latency live streaming (and they have contributed to its development): https://www.youtube.com/watch?v=o5sJX6VA34o

                    The installed base on VP9 decoder support is double the installed base on HEVC support. VP9 has done pretty well for itself and AV1 will do better: https://ngcodec.com/news/2017/10/21/...ng-vp9-and-av1

                      The next codec (AV1) will be used by these companies: http://aomedia.org/about-us/

                      Even the founder and chairman of MPEG, Leonardo Chiariglione, says HEVC has no real future due to its licensing and maybe even MPEG as an organization is finished. He says the future is AV1 and the Alliance for Open Media: http://blog.chiariglione.org/a-crisi...nd-a-solution/
