GPU advantage

Post by trumee » Wed Jul 01, 2020 1:43 am


Is there any advantage of using an Nvidia GPU with zoneminder? I want to reduce the CPU usage without reducing the resolution or frame rate.

Not exactly the answer you're looking for, but I used the GPU cores in my AMD APU to lower my CPU usage by about 20%. So it will lower it, but not a huge amount. For 5 cameras, it was good enough to get my usage down from tipping 100% to 70-80%.

Just go into the cameras settings and you can enable hardware decoding under source-> DecoderHWAccelName. Look up the name for the nVidea decoder you want to use. nVidea hardware decoding is generally better supported, so you might get better results.

Search the forums with term 'GPU'. this has been answered multiple times, e.g.
fastest way to test streams:
ffmpeg -i rtsp://<ipaddress>:554/path output.mp4
from terminal, and run through paths on ispydb or in zm hcl
