I have the settings set on the Apple TV to 720p 4 mbps. Also set to linear. I noticed high cpu usage when I watching the activity monitor on my Mac. VTEcoderXPCservice was running at nearly 300% cpu. Is this normal?
I was watching another tv show remotely on a different tv also, if that helps. But that was a "live tv" show.
Just tested it out with two live shows and found out the CPU kicks up when the 2nd remote stream starts. Is it using hardware encoding for only one stream?

It depends on your CPU model and macOS how many are supported. It will switch to software when no more hardware as possible
Its a sandy bridge i7. Running High Sierra. Would you know the limit on that? What are the approximate limits of the new iMac or Mac mini?
Can the GPU be used for transcoding instead of the CPU?
We just use macOS VideoToolbox and cannot control how it works or what the limits are.
So out of curiosity....how many simultaneous hardware transcoding sessions can happen on Intel’s 8th gen CPU’s?
I’m very happy with my i3-8100 build, but I’m curious on this
Me too. I am just looking at a new configuration for a windows PC dedicated to just the DVR. I am looking at getting a NVIDIA Quadro P1000, 4GB in the machine. Would that help with my problem of streaming to more than 1 or 2 remote devices?
I've been wondering about this as well too, having just got a new 2018 Mac Mini. The Devs have put a lot of useful tools into the server package, such as speedtest, it would be cool if there could be a hardware test that would tell you how many simultaneous HW transcodes or SW transcodes your system could do simultaneously.
Looks like that GPU supports 2 concurrent sessions according to https://developer.nvidia.com/video-encode-decode-gpu-support-matrix
Is there a spec sheet for amd video cards too? I can't seem to find one
So the P2000 would be my best bet? I could put this into an older computer with an i3 ivy bridge processor and it should work fine with 4 or 5 different remote streams? I plan on putting the OS on a SSD and having the DVR save to a 8 or 10 TB HDD.
I think so but I have no experience to know for sure
Just purchased a P2000. I'm going to be putting it into an old dell 390 with an i5 with the OS on a ssd and the dvr will be saving to a 10 TB drive. I'll keep posting to share my experience. I know it's extra money but I think I can justify paying it when I would be paying spectrum $80 a month for tv and DVR.
I am pretty sure I can actually get upwards 15 streams but I have not had a chance to get that many streams running. It’s on my to do list.
What resolutions are you streaming 720 or 1080?
I was able to stream 3 720p 4mbps dvr recordings at the same time with a P2000. Although, the P2000 cpu was around 80% used and the CPU was still using 90-95%. Is this normal?
