No sane person would throw out still good Hardware to get a new one with Hardware decoder for the new Codec. So you will have a lot of User that will rely on SW decoder And we have no AV1 Hardware decoder ready to buy yet(they are planed 2020)
Hardware decoder are mostly to improve Battery life. If your Device is always plugged in, it does not matter that much (As long as the CPU is fast enough for SW encoding)
Well i use my Odroid N2(arm64) as my main device at the moment. I can decode AV1 without problems 1080p30fps (could be more now i have not checked for the improvements of dav1d 0.5)

Guest repliedOriginally posted by schmidtbag View PostNow that's the kind of stuff I like to see for decoders. We have enough AV1 encoders out there that depend on modern instructions or APIs, but not enough stuff that can work on real basic systems. ARMv7 may be old but it isn't irrelevant. Of course, the speed improvement doesn't necessarily say much about whether it can play certain videos smoothly on such systems (not sure if it ever could or couldn't).

Phoronix: dav1d 0.5.1 Boosts AV1 Video Decode For Older CPUs by 40~50%
While marketed as a point release, the dav1d 0.5.1 "Asiatic Cheetah" release is quite significant for those needing to perform AV1 video decoding on older processors...
