Note how we routinely decode VP9 in software on phones.

That's significant even if it is not a true ASIC hardware decoder, and it's not really true "software" decode, any more than AES-NI (crypto acceleration instructions in x86 CPUs) is "software crypto".

If you're lucky, as well as MJPEG you also get h264 support.
EDIT: And hopefully you picked a board without USB controllers that cause kernel panics if you don't insert the cable just so.Last edited by archsway; 29 October 2019, 02:15 AM.

I don't recall seeing hardware VP9 decoding on mobile devices.

It is better if you can view a AV1 file on older Hardware, than to have no way to open it. Hardware decoder need Kernel support so you will end up with a lot user who will rely on Software decoding until it is in the Mainline Kernel.
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)
And for Encoding https://github.com/xiph/rav1e/issues/1754 rav1e does merge the Arm64 assembly from dav1d. It will take a lot of time to encode with it but why not use a Raspberry Pi like device that you have lying around in your closet. (maybe arm32 too)
