Serious question:  What's the idea of playing 8k video?  Do you have a display of some sort that can show 8k worth of resolution?  Or is this more like playing with the next big thing that might be viable on a real display in 2 to 5 years?

If I had to guess, playing 8K back (e.g. downscaled) to 4K or 1080p probably looks rather good. Kinda like some 4K YouTube videos downscaled to 1080p looks pretty nice.

Dell released an 8K monitor a few months ago, and high-end televisions will be going 8K in the next 6-18 months. The goal in Japan/Europe is to be broadcasting 8K by the 2020 Olympics.
8K downsampled is much higher quality than anything else streaming on the web right now.
It's not perfect, but is much closer in quality to what you get from disc-based media.
 
I wish I knew what changed that has stopped hardware acceleration working for 8K videos with LAV Video now though.
I can only think that it's something relating to a Windows Update, as I've downgraded video drivers and LAV versions and it's still using avcodec (CPU) instead of dxva2n (GPU) for decoding.
CUVID enables hardware acceleration with vp9 but not avc1 encoded videos, however it is too slow to play them back smoothly - just like dxva2cb.
Playback still works in Edge though.
 

I tested it again -  the MC process consumes ~2.7 GB on my PC. Downscaling from 7680x4320 ->3000,1440. madVR says no frame drops but rendering time is ~59 ms!-> slow motion, but it does not crash.

Until hardware acceleration is fixed, it won't be crashing because your system (or virtually any system) is not fast enough to decode enough frames into memory to cause it to go over 3GB RAM and crash - which is why it's playing in slow motion.
