Insane CPU usage - Githubissues

OtaK commented 2 years ago

Hi!

I've been seeing some CPU usage threads with dual/quad cores being relatively used and I'm having quite the issue:

Yup. This program uses 100% of my 32-core Ryzen 9 5950X, causing issues with other things, cracking audio etc.

I have a small question, could it be possible to have a flag/feature-gated GPU-backed processing?

This is being quite bothersome as I'm currently using this program for business meetings and well, it basically prevents me from using my computer at the same time.

FYI I run this program with the following configuration:

width = 800
height = 600
fps = 30
background-image = blurred-bg.jpg
background-blur = 0
background-keep-aspect = yes
no-background = no
no-foreground = yes
no-postprocess = no
select-model = 0

Specs:

CPU: Ryzen 5950X
RAM: 32GB DDR4 3800CL14
GPU: RTX 3080

Thanks!

What is the version of your Python and OpenCV? Which distro are you using? I guess I need to write a frame rate limiter for higher performance machines.

Hi! Sorry for the late answer;

Python: 3.7.10 OpenCV: 4.5.4

As for my distro, I'm running Funtoo (up to date) with a 5.12.19-ck SMP PREEMPT kernel
