Question / Help Questions about RTMP Server dual PC streaming and general streaming

[sorakles]

Hey guys,

I finally decided to start my own stream. For now I have my stream layout and OBS Studio set ready for everything. It is no problem to stream from my main machine in 720p and 30fps. But still I am getting lower frames in my games while this is fine for games that are not that demanding I kinda struggle in fps, I also want to use my 120herz monitor.

I tried many diffrent settings and I got some fps increase but I am not stable and not near 120 fps. So my next step was to get some information about dual PC streaming.

Is its possible that FFmpeg is encoding complety by itself and that my main machine is not doing anything with encodeing? What hardware should I get for the 2nd PC? I am kinda lost right here. The Goal is to stream in 720p at 59 fps with 120 fps on my main machine ( I have about 120-150 fps right now when I am not streaming).

I have a intel i7 3770 in my current machine - but because I am kind of in a budget I can use the i7 to encode only and buy me a AMD/Xeon setup for my gaming rig. I need a Mainboard, CPU (Gaming/or Encoding) and a small computer case everything else I can use from older systems.

I would greatly appreciate your advise.

If you're on a budget I would try this: https://obsproject.com/forum/threads/guide-two-pc-configuration-without-capturecard.6757

Instead of Quicksync I would get an Nvidia card and do NVEnc encoding to the streaming PC... there's no less CPU-intensive way than that to send the video out to the streaming PC.

Just as a small addition I'd like to chime in my experiences with the nginx/rtmp-solution. I used to do NVenc for quite a while, but had lots of issues where my GPU-utilization hit 100% and artifacts just like when overloading your normal CPU happened. In my case I was almost only streaming Arma3 which didn't load the CPU as much as it pounded the shit of my GPU.
So, what I'm trying to say is what hardware encoding you go for should be based on your actual activities. In my case QS was the way to go, in other cases NVenc might. YMMV :)
