AOMedia Codec Workgroup Approved version 1.0

AV1 Bitstream and Decoding Process Specification

It is now a little more done than it was in March. ;)

AV1 decode is enabled by default in Chrome 69: https://www.chromestatus.com/feature/5729898442260480

I played it with Chrome 69 Dev. Not so great performance, but I expect that to improve soon. Make sure chrome://flags/#enable-av1-decoder is enabled.

Firefox Nightly should also be able to play it..

No, Chrome 69 (Opera 56) will be the first stable and beta to have it. It debuted in Chrome 65 Dev, but was “not ready for the beta channel”. (The specification was frozen 25 June.)
