    Phoronix: The Rapid Progress Of The AV1 Video Format Over The Past Year

    Mozilla presented at the NAB Streaming Summit last week over the state of the royalty-free AV1 video format aiming to compete with H.265/HEVC and succeeding VP9 for open-source use-cases...

    The PDF is a very interesting read: https://people.xiph.org/~negge/NAB2019.pdf
    There is also a citation and screenshot of Phoronix....

      Presto is almost done encoding. It's just over five minutes and is coming up on 48 hours. I'm using libaom with cpu-used=1.

        LMAO! You can't make this stuff up. 48 hours to encode 5 minutes. According to the slides, the encoder is supposed to only be 3 times slower than x265.

        This is basically going to be a Netflix/YouTube exclusive. Unless you are distributing videos to millions of people, it's just not worth it.

          Too bad VVC (h266) is a year and a half away from finalization. AV1 is supposed to compete with h265, not h266. :'(

            If you're into future MPEG formats, look to EVC.

            VVC looks to me as if determined to be yet another crippled license bastard that will take 10 years to adopt. What I think is necessary is a defensive development process (not just licensing talk in MC-IF), and to totally redefine FRAND licensing to actually permit free software implementations (as HEVC Advance began). EVC is doing the first, not the latter, but will at least have a royalty-free subset, which I think will help it a long way.

              That's libaom. If you tried to encode anything with the HEVC reference encoder, you may never complete it. If you are doing chunked steams like MPEG-DASH or HLS, sure it could cost a bit of money to run the machines, but you can get things encoded quickly, whether you're YouTube, Netflix, or just some dood with an AWS/GCE/Azure account.

              Also, a single decent machine can encode AV1 at standard framerates and resolutions in real time right now, with SVT-AV1.

                If I would have used --cpu-used=5, it would have been done long ago. But I chose --cpu-used=1 on purpose.
