Anyone can help ?

My OS: Linux Mint 19.3 Cinnamon

[alievk]

Something wrong with the virtual cam. Please show v4l2-ctl --list-devices output and CAMID_VIRT value.

[eltonnuness]

v4l2-ctl --list-devices

avatarify (platform:v4l2loopback-000):
/dev/video9

C922 Pro Stream Webcam (usb-0000:00:14.0-10):
/dev/video0
/dev/video1

echo $CAMID_VIRT
9

[alievk]

Your setup looks ok, but pyfakewebcam can’t open the virtual cam for some reason.

This is related issue jremmons/pyfakewebcam#7

[barabanshek]

Exactly, the issue was in the v4l2loopback driver.

You need to change the line 2095 in the file https://github.com/umlaeute/v4l2loopback/blob/master/v4l2loopback.c#L2096 to #if LINUX_VERSION_CODE >= KERNEL_VERSION(3, 7, 0) and build, re-install the driver. This worked just fine for me.

More info here: umlaeute/v4l2loopback#172

[alievk]

Added fix branch. Do:

# remove apt package
sudo modprobe -r v4l2loopback
sudo apt remove v4l2loopback-dkms

# build v4l2loopback from source
# from avatarify directory:
git pull
git checkout fix_v4l2loopback
bash scripts/install.sh

[alievk]

Please write back if it works.

[eltonnuness]

It works ! 👍

Thanks @alievk and @Prockuror

I am having a similar 'pyfakewebcam.py' issue.

v4l2-ctl --list-devices
avatarify (platform:v4l2loopback-000):

(avatarify) stefan@stefan-4930:~/Downloads/avatarify$ echo $CAMID_VIRT

So I set CAMID_VIRT myself in the command line with

$ CAMID_VIRT=9
before running 'run.sh'
and got this:

help?

[alievk]

@bwanaaa does it help compiling v4l2loopback from source? #37 (comment)

[bwanaaa]

it seems thie issue here persists
umlaeute/v4l2loopback#172

the line 2098 in the repo is still

#if LINUX_VERSION_CODE < KERNEL_VERSION(3, 20, 0)

whereas the closed issue indicates it should be

#if LINUX_VERSION_CODE >= KERNEL_VERSION(3,7,0)

[bwanaaa]

There are so many references to 'KERNEL_VERSION' I dont know which to change to the '>' from the existing '<'

[alievk]

Did you try #37 (comment)? I've already changed that line.

[bwanaaa]

I followed comment 37 to this point 'git pull' and got

[bwanaaa]

I did compile the latest v4l2loopback from source and did install it first.

[bwanaaa]

and now it works. thank you.

[serg-zh]

had the same issue, #37 (comment) helped

[nathaniel-brough]

I have the same issue but comment #37 did not solve my problem.

The first bash run worked with me and got the virtual camper working with zoom, but when I closed it, I made a restart and reopened again, it showed the same messages error like anybody here. I tried may time to remove v4l2loopback and reinitiate everything but I keep getting the same error, even I tried on another ubuntu 16.0.4 machine and the same thing happened!!!. I don't know what happened in the first bash run command, I installed all dependencies again (pandas, NumPy, cv2 .... etc) and then worked without any virtual camera error. anybody solved it or know what is the problem and possible solution?

[alievk]

@basemdabbour not sure I understood it completely. did you manage to run it without error?
Do you have latest version of code?

[basemdabbour]

@alievk yes, I did without any errors after installing dependencies in my condo environment, I used the same code in repo, it worked with me by following the same steps. but only one time :). but when I restarted my OS and tried to run "bash run.sh" again, I got the same error here and couldn't fix it till now.

now I am getting the follwoing error:

[basemdabbour]

@basemdabbour not sure I understood it completely. did you manage to run it without error?
Do you have the latest version of code?

@alievk, I got two windows, one is cam and the other one is avatarify with Einstein's face. also worked integrating it with zoom like you did in the video. I stopped and rerun "bah run.sh" many times and it worked. but suddenly it stopped working and now I got again the same error :

FileNotFoundError: device does not exist: /dev/video9
FATAL: exception not rethrown
run.sh: line 17: 19128 Aborted

[basemdabbour]

@alievk Finally, it worked with me and using the GPU.
I just changed my operating system to use Fedora instead of ubuntu and everything went just perfect without asking me about any missing modules or CUDA problems. but unfortunately, I have a low VRAM and the streaming was not clear enough to do a call :)

[alievk]

Glad to hear you get it through :)
There are lots of exceptions happening, it's hard to make it run on all the diversity of platforms and distributions..

@alievk yea you are right it's a pretty good project and I think there is a new bug in the zoom or skype where it allows you to add virtual camper to their application!. This project is just highlights the possibility of doing it. But how can I change the avatar? to Elon musk for example?.
