A video with a 4320p (7680×4320) playback option has appeared on YouTube. According to the video description for "Ghost Towns in 8K", it was "Filmed on the RED Epic Dragon 6K in Portrait orientation and then stitched together in Adobe After Effects. Some shots simply scaled up by 125% from 6.1K to meet the 7.6K standard."
Very few people on the planet will be capable of playing the upscaled video in its full glory. The NHK and Panasonic plan to trial 8K broadcasting during the 2020 Tokyo Olympics. Perhaps YouTube should add an intermediate 5K (5120×2880) option for Apple and Dell users.

New Intel/AMD/ARM CPUs and GPUs have hardware support for H.265 (and maybe VP9) decode.
I can decode H.265 720p on a 4 year old cheap laptop (no hardware support for H.265), so you are overestimating the requirements. Can it do 1080p? Apparently not. When I try playback I get skipped frames and other oddities although some of it will play. But the laptop doesn't even have a 1920x1080 screen so it's useless anyway.
Not true. That's likely the lowest bitrate they tested at.
https://en.wikipedia.org/wiki/High_Efficiency_Video_Coding_tiers_and_levels [wikipedia.org]
There's a maximum bitrate of 128 kbit/s for level 1.
I'm going to try to use Handbrake to convert an H.265 video to a double digit kbps H.265 video.

The question is Linux/BSD drivers for that H.265 hardware acceleration (co-processing)..
How is H.265 compared to VP9 quality, bitrate and processor demand wise?
That 4 year old cheap laptop. What CPU, frequency, memory type and frequency and screen does it have?
And if you get sent an 1080p video, one will have to decode it and then rescale. So it's not the screen that matters really but the input format.
It would be kind of interesting to know the minimum bitrate for decent H.265 video at 480p, 720p and 1080p. Could be useful for camera feeds.. if one finds an embedded solution to compress the raw video.
On a technical note I find H.265 capability to use any block size transform kind of "hey why did it took them so long?" ;-)
Those prediction and filtering algorithms are interesting and tough to get right.
