High CPU usage when watching DVR show remotely


#1

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?


#2

I was watching another tv show remotely on a different tv also, if that helps. But that was a "live tv" show.


#3

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?

#5

It depends on your CPU model and macOS how many are supported. It will switch to software when no more hardware as possible


#6

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?


#7

Can the GPU be used for transcoding instead of the CPU?


#8

We just use macOS VideoToolbox and cannot control how it works or what the limits are.


#9

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


#10

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?


#11

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.


#12

Looks like that GPU supports 2 concurrent sessions according to https://developer.nvidia.com/video-encode-decode-gpu-support-matrix


#13

Is there a spec sheet for amd video cards too? I can't seem to find one


#14

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.


#15

I think so but I have no experience to know for sure


#16

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.

@thechannels got six streams off the P2000: Cheapest add-on GPU for hardware transcoding?

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?
