We got many questions about PC requirements for SRTMiniServer
It strongly depends on the parameters of incoming streams.
For example: my notebook with Core-i5 uses 17% for 4 incoming streams of HD@25fps/2Mbs (see details below)
Before let me note SRTMiniServer does two expensive operations:
Let's go over these points
SRTMiniServer allows select "software decode" or "hardware decode"(means GPU). But we recommended use "software" in many cases.
Resume: using CPU for decode is preferable.
NDI uses only CPU. No options.
GPU does not make sense
CPU is make sense. We recommended use Core i7 or Core i9 and 16 Gb RAM.
Perfomance very sensitive to incoming feed: 4K@60fps and HD@25fps show different CPU usage.
So common recommendation is make stress-test for got real perfomance of your PC.
For stress-test you need (on other host):
If you plan use HD@25fps / 5Mbs, then prepare mp4 (h264/aac, HD@25 5Mbs) duration ~5 mins.
Use this command for send SRT stream to SRTMiniServer by ffmpeg:
ffmpeg -re -i hd_25_example.mp4 -vcodec copy -acodec copy -f mpegts "srt://192.168.1.53:9001?streamid=streamkey1ABC"
you need change IP and streamid for your value
You can run many commands (with different streamid) at same time for generate many feeds. For example I run 4 feeds to check my notebook for HD@25fps feeds:
my notebook with Core-i5 uses 17% for 4 streams of HD@25fps/2Mbs
example: I run few streams from macOS
Built-in Preview window takes CPU for rendering, so no reason use it on slow PC long time. In our test we got increase CPU usage from 17% to 35% when open Preview window
