Thanks, I used the Halo video[0] to compare, a couple of notes.
- Youtube seems to have limited the AV1 support to 1080p, 1440/2160p are not available, anyone any idea why?
- The load on my CPU (MB Pro 2018 quad-core/ FF DE 67.0b9) seems about the same but I do seem to be dropping significantly less frames, not sure though.
it was probably encoded at a time when they didn't do 4k av1 tests but only 1080p, but since then they also did a 4k one if you wanna test it https://youtu.be/LXb3EKWsInQ
If you want to test this right now, here is how to enable AV1 in Youtube and test videos.
Goto the youtube testtube page and click "Always Prefer AV1" https://www.youtube.com/testtube
AV1 Beta Launch Playlist

And click "stats for nerds", if it's working it should show "av01" under the Codecs tab.
