How does this compare to VP9/10 by a "human quality" metric? There's lots of cherry-picking about stats which makes an encoding sound impressive on paper but result in a worse perceptible quality. This is a really good article about testing encoders: https://blogs.gnome.org/rbultje/2016/05/02/the-worlds-best-v...

Additionally, adoption is really slow of VP9 already so I don't see anyone switching to Daala soon.

No one will switch to Daala. They'll switch to AV1. As other commenters have noted, the AV1 codec is built from Google's VP10, Mozilla and Xiph's Daala, and Cisco's Thor. Wikipedia has a good summary of AV1: https://en.wikipedia.org/wiki/AOMedia_Video_1

And if you're interested in the source, the AV1 git repository is: https://aomedia.googlesource.com/

We use a wide variety of metrics to compare codecs, not just the usual PSNR metric:

While none of these metrics are as good as the "human quality" metric, some are better than others, in different ways, so we try to optimize across the board.

On that note, have you considered adding Netflix's VMAF to AWCY?
