From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Finally, a pi good for 4K video! (Apparently Raspberry Pi 4 could as well, but I am assuming this is an improvement. I still have a couple of Raspberry Pi 3's.)
It doesn't have h.264 hardware decoding though, so ironically 4k HEVC/h.265 will probably play just fine but 1080p h.264 might struggle depending on your cooling solution.
The folks at Libreelec say it can software decode 4K h264 smoothly
I wonder if it'll be powerful enough to run a Jellyfin server and actually handle some transcoding now
Are you sure they said it'll decode 4k h264 smoothly? I'm seeing them saying 1080p is good, but not 4k.
Here's a quote from the article you linked, emphasis mine:
Note that it's unclear from this quote what Codec the Youtube stream was using, but remember that Youtube is quite low bitrate even at 4k. The implication here is that 1080p h264 is good and low bitrate 4k stuff might be okay, but it will struggle beyond that. Keep in mind that it's not any worse than RPi 4 in that area, but I don't think it's going to be much better either.
You quoted those two sentences, but skipped the three sentences right before them:
To my eyes this implies it works fine for 4K h264. The sentences you quote from are sort of a "furthermore, at 1080p it can handle these more complex codecs as well" to my initial reading.
I'm not saying you're wrong, just explaining why I parsed this paragraph a bit differently.
That seems to work for my needs. The performance improvements according to this video seems promising: https://yewtu.be/watch?v=9hYfQ7bRgZg
Then again, after learning about the crappy things the Raspberry Pi Foundation has done, I'm probably better off getting a used Lenovo ThinkCentre or HP EliteDesk Mini (which I already have) for a much lower cost. I was just excited about Raspberry Pi's finally being powerful enough to handle 4K, but that may be a stretch, too.
You won't notice a difference in h265 4k video as each has a decoder, but Youtube performance would definitely be improved. My Rpi4 struggles with 4k60p youtube videos because it lacks a VP9 decoder.
Sadly no hardware AV1 decode though. Though it can apparently decode AV1 in software up to 1080p.
I don’t know about lately, but 4k on Pi 4 was always janky.
