Almost a month has passed since the freezing of the bitstream (2018-06-26). Official samples posted somewhere?

It's written from nothing, however it does link in some CDF tables and the transform SIMD code from libaom as we haven't written our own yet.
If you run "make testdata" in libaom you'll get a ton of test ivf files that are used to verify the decoder. They are as close to "official samples" as exist right now. Last edited by TD-Linux; 20th July 2018 at 23:28. |

Well, the encoder has gotten 2-3 times faster in the last 4 months. It still needs to be at least 50-100 times faster to be anywhere near being usable as an encoder. Maybe they pick up the pace now that the bitstream is finalized, but i'd say it will probably take more than 12 months.

You are an optimist. According to my calculations, the codec needs to be accelerated 1000 times.

Lol, i try to be realist. AV1 is a much more complex codec than VP9 or h.265, so i can accept that it will be slower. 1 fps at 720p for the veryslow preset equivalent would be acceptable to me (assuming no serious quality degradation of course). Although you're right, that'd need probably more than 100x improvement.

But more importantly, a usable encoder would mean youtube could finally improve the video quality, assuming of course that they dont use the improved efficiency to lower the video bitrates. |

Holy crap guys, the latest Chrome Canary has a significantly improved AV1 decoder. You can play this http://video.1ko.ch/codec-comparison...18-06_550.webm 1080p test stream using very little CPU.

Yeah you need to enable AV1 decoding in the options.
