Does Duo send H.264?

As far as I've read about Duo it seems to be AV1:

...though I'm not sure whether they use it consistently.

How does this happen? AV1 encoding codec was still work in progress, and most chips don't support any hardware acceleration for this. Can we get reasonable frame rates on core CPU for av1 encoding already?

Duo uses AV1 for very low bandwidth calls. And then a mix of H.264 / VP8 / VP9 etc.. depending on many parameters. Disclaimer: worked on the product. https://blog.google/products/duo/4-new-google-duo-features-h...
