the computer on the left is fast enough and has enough memory to store the entire video decoded as raw framebuffer in free video memory.

And if Chrome attempted to do that, then everyone would complain about how it's crashing their videogames while multitasking. Plus you'd have to cache aggressively to allow smooth seeking. And then it only works for HD videos up to 30 seconds which is what you can fit in there.

you only need as much as you are willing to make instantaneous for the user. even just 50 ms or whatever is good enough. better than the infinity milliseconds (until you stop moving mouse for 250ms) of the player on the left. you're imagining 100% ideal vs what's necessary

50ms of *what*? *where* in the video? You do realize that 50ms is 2-3 frames, right? What good does that do you?

the video is 30fps. i'm talking about 50ms between updates while the user is scrubbing. are you just trying to find arbitrary things to question me about?

Have you considered that computers run off of batteries these days? Pegging the CPU while seeking is quite a silly thing to waste battery power on, just to give slightly faster screen updates. If you *really* care, there are players that can do this, and good reasons not to.

it's using 100% cpu on 1 core while seeking in the left video already

Okay then *that* is broken.
