What generation CPU would you suggest for ability to down-encode fro 4k/2k/1080p to 1080p / 720p at a sufficiently fast speed to be used as a streaming server?
Just use clients that have enough power to direct-play the content on their own. Let the display handle the 4K to 1080p downconvert on its own (most displays can do that, since it's just a matter of halving the horizontal and vertical scales). At that point, it's just a fileserver with a fancy catalog.
let the display handle 4k to 1080p downconvert
Not even remotely what I want.
I didn't think I would have had to flat out say my internet can't handle 2k/4k.
e: Also a display doesn't downconvert. If you give a 1080p capable screen a 4k signal it will tell you to fuck off.
You want an NVIDIA 1050Ti for hardware transcoding of multiple streams, and then you'll want to run it on Ubuntu, not Windows. CPU Encoding is not where its at. Set your max stream rate to something like 8mbs to get good 1080p streaming. Also, if anything is in H265 format, CPU transcoding is pretty much a no-go. You need GPU-based transcoding.
