High cpu usage 200%
wbender-wurl opened this issue · comments
Hi, no matter what I do I get high cpu usage. Even if I don't do any frame processing.
python3 fake.py --no-foreground -W 680 --no-ondemand --no-background

Description: Source for the v4l2loopback driver (DKMS)
This module allows you to create "virtual video devices".
Normal (v4l2) applications will read these devices as if they were ordinary
video devices, but the video will not be read from e.g. a capture card but
instead it is generated by another application.
.
This package provides the source code for the v4l2loopback kernel modules
to be built with dkms.

$ python3 --version
Python 3.8.10
I haven't received this report from other users. I will leave it open here. Hopefully someone else can comment on it.
I'm also at 200%-300% CPU usage.
On Arch Linux (5.13.10-arch1-1), AMD Ryzen 7 3700X CPU, Python 3.8.11, with Akvcam.
I pinned MediaPipe version back to 0.8.5, please let me know if the bug still exists.
For me, this has not changed anything in terms of CPU usage.
I personally cannot replicate the issue. I guess people just have discuss amongst themselves.
I'm seeing this issue as well on Gentoo, Intel Core i7 7700, Python 3.9.6, using v4l2loopback
It also segfaults after a while
