Hey, I have this error showing up when trying to run sudo python3 main.py:

Traceback (most recent call last): File "main.py", line 11, in <module> import v4l2 ModuleNotFoundError: No module named 'v4l2'
Please help :)

When running:

sudo modprobe v4l2loopback video_nr=20 card_name="Virtual Camera 1" exclusive_caps=1

I'm getting:
modprobe: ERROR: could not insert 'v4l2loopback': Operation not permitted

When using this background changer (installed flawlessly on pop OS 22.04) I am getting a weird overflow of the background on my face. Is there anything I can tweak to make it less overflowing?

Hello, I was trying to run this and I am unable to get it to run. I followed the instructions and I had an initial no cv2 module. So I installed cv2-python through pip3. Then I got no v4l2 module and installed that through pip3 also. Now I am getting the following error:

sudo python3 main.py         
Traceback (most recent call last):
  File "/opt/MS-Teams-background-changer/main.py", line 11, in <module>
    import v4l2

    ) = range(1, 9) + [0x80]
TypeError: unsupported operand type(s) for +: 'range' and 'list'

Unfortunately there's not much more to report. The dummy camera simply doesn't show in MS Teams.
If I try to view the output through guvcview it does list the camera, but can't show a stream.
The source webcam is active after running main.py, and there are no console errors...
Are there any steps I can try to debug this or provide further information?

Hello. Thanks for your help. Im running fedora 36 and first time script run ok and second time is showing this error. Any ideas?

When using the blur option, the output is, while kind of cool in its own way, but obviously not what I'm after.

The console looks normal with Processing frame: being output.

When attempting to use a bg_image however, it simply crashes and refuses to process any frames.
I've attached the output here.

Any clues?
Cheers :)

PS - I also followed this guide to get the GPU recognised by TensorFlow

OS
Ubuntu 20.04.4 LTS 64-bit

Graphics
Mesa Intel® Xe Graphics (TGL GT2)

Steps followed / commands executed
I followed steps from readme. Runnning v4l2-ctl --list-devices shows:

$ v4l2-ctl --list-devices
Dummy video device (0x0000) (platform:v4l2loopback-000):
	/dev/video20

Integrated Camera: Integrated C (usb-0000:00:14.0-8):
	/dev/video0
	/dev/video1

I updated the cameraID setting in ./config.yaml to just use the number as so:

# change input camera device ID (just add the ID number alone)
cameraID = 0

Running python3 main.py shows this output (with the Processing frame logs continuing until I stop the script):

...

I then fire up a camera app (e.g., MS Teams) but the camera only displays a black image, no video and no virtual or blurred background.

If I have the physical camera in use before running the python3 main.py script, then I get the error:

[ WARN:[email protected]] global /io/opencv/modules/videoio/src/cap_v4l.cpp (889) open VIDEOIO(V4L2:/dev/video0): can't open camera by index

So I assume it is correct to run the script prior to starting the physical camera.

Am I missing a step or anything?

Edit: After doing some more digging, I realize perhaps this is due to my graphics card not being supported sufficiently for running TensorFlow? If that's the case, feel free to close this issue.

ctrl+q not working

Hi everyone!

I'm on Pop!_02 22.04 (up to date), and while trying this, managed to have all ok, except that it fails at startup like this:

Do I need to install TensorRT ❔
