Transcoding anything >720p is painful.
I run ancient hardware for desktop/laptop >10yrs old apple stuff running linux. I consume media mainly via rpi4 or android.
What’s a minimum level system capable of trans-coding 4k video to x265 in at the very least real time? Is there a tiny trans-coding device out there somewhere?
Would a NUC do? How old or new to churn out 4k x265
Can I avoid hardware? Are cloud gpu’s a thing?
So I think you may not know about quick sync, an Intel transcoding acceleration feature of Intel gpus in Intel CPUs.

There’s information about it for I think plex and handbrake and ffmpeg in general. This is how some people do real time transcoding for media servers. But I’m not an expert. I just hope you can be guided with easier search terms.
What a great example for the community you are, my guy. I love it.
Speaking up, knowing you don’t have the full answer but can at least point in a general direction, is HUGE in a community full of constant and rapid change where the previous years information could already be outdated or even obsolete.
