NVidia Decode/EnCode

Post by mcamino » Fri Jun 11, 2021 3:18 pm

Hello,
I am looking to supplementing my existing BlueIris install with an NVIDIA card. I was thinking about the GTX1050TI since it fairly cheap and supposedly can do 3 ENCODE streams simultaneously. (see link https://developer.nvidia.com/video-enco ... matrix-new)

I have 8 cameras at 1080p@15fps, and my current setup works reasonably well, but the cpu hovers at 70%. My question is does that mean the first 3 cameras will be done in hardware via CUDA and the rest will still be done in CPU? I have direct-to-disk as well as the rest of the normal recommendations followed, however my cpu does not support quick-sync. I am not sure the definition a "streams" and how it relates to video camera recordings. I would think this card could handle 8k@60fps per the specs so i would think it could handle my cameras, atleast theoretically. What do the experts think here? Any suggestions of a good decoder card to do what i need?

I am using a GTX1050TI to decode 10 4mp cameras anymore the decode stopped working.

I only do Intel decoding but you should be able to set the type of decoding you want each camera to do in the 'Video' tab of each. There is a default option which will revert to the system default value but otherwise you could set half to Intel and half to Nvidia (in theory). I wasn't aware of a device count limitation until the CPU/GPU is maxed out, but maybe there is.

That said, depending on your existing CPU, there may be room to optimize it your current config further so that your CPU is more reasonable.
