Yeah, it will still be a while before anyone can fully get away from h264, but with Apple adding AV1 decoders to their latest chips, hopefully all the wheels are at least in motion now.
Yeah, that's true. I did see something from Meta recently where they were delivering lower resolution/bandwidth AV1 to devices that didn't have AV1 hardware decoders, but had enough CPU for software decoding of the smaller renditions.
