My laptop has hardware AV1 encoding and decoding. My TV has AV1 decoding. My phone has AV1 decoding. None of these devices are particularly new.

And don't underestimate dav1d (https://www.videolan.org/projects/dav1d.html). You can comfortably play AV1 video in software on your phone. Try it with VLC.

Maybe for about 15 minutes before your battery is drained to 20%. I'm not aware of any software video decoder at all that won't unacceptably heat up your phone and kill your battery.

You really are underestimating just how far e.g. Apple's mobile CPUs have come in terms of raw performance and power-efficiency.

Why say maybe? Why not simply try it for yourself?

I don't need to try it myself to know that software video decoding on the CPU is not a viable solution on mobile phones.

Of course it is. Even the iPhone 7 from 2016 can play 1080p AV1 video.

Why did you spend all that money on your phone if you're not going to exercise the hardware?

Not OP, but 2hr battery time for video playback vs 20hr would be the entire point of this thread. HW decoding is an order of magnitude more efficient.

That isn't the benchmark set by petcat. petcat's goal post is 15 minutes to 20% battery with AV1 playback.

It's baffling that petcat won't simply try it. Maybe he has awkwardly discovered he does have hardware AV1 support after all.

I've still got my old iPhone 7. I'll dust it off and do the experiment. I think it'll do at least 90 minutes in VLC.
