Hi, thanks for making this, it would be very useful to use it in Teams!
Just wanted to mention that pip is not listed as a dependency, and it is not always included in the python package depending on the distribution; i.e. on Arch there's python and python-pip separately.
Also, after running make and running the script, I get:
sudo ./bgrm.sh
INFO: Created TensorFlow Lite XNNPACK delegate for CPU.

I have patched it and everything
something interesting: i changed pip install virtualenv to pip install --user virtualenv because pip without --user breaks python-exec on gentoo
Hello!
I have tried to build and use bgrm on my machine, I was very excited to try it out :-)
First problem was that I could not build the kernel module and the output was not too helpful. Later on I realized that I haven't had the kernel headers to build the module. On openSuse it should be enough to install the kernel-devel package, but I have installed the kernel-sources package and that installed kernel-devel as dependency. After this the kernel module build was successful, perhaps mention this in the Readme.
The next problem was when running bgrm.
...
cp: cannot create regular file '.venv/lib/python3.9/site-packages/v4l2.py': No such file or directory
...
I verified the path manually and for some reason on my machine the path is with python3.8 not python3.9:
.venv/lib/python3.8/site-packages/v4l2.py
So I edited that path in bgrm.sh and tried again, but this time it complained that opencv-python is not installed:
$> sudo ./bgrm.sh -b ~/Pictures/Teams/ISS-cupola.webp -H 720

raise DistributionNotFound(req, requirers)
pkg_resources.DistributionNotFound: The 'opencv-python<=4.4.0.46' distribution was not found and is required by the application
However, when I try to install it manually, it the requirement appears as satisfied:
sudo /home/user/Applications/bgrm/.venv/bin/python -m pip install opencv-python
Requirement already satisfied: opencv-python in ./.venv/lib64/python3.8/site-packages (4.4.0.46)
Requirement already satisfied: numpy>=1.17.3 in ./.venv/lib64/python3.8/site-packages (from opencv-python) (1.21.3)
So now I'm not too sure what to do anymore, any ideas would be helpful!
And last but not least: thanks a lot for doing this!
Getting an error while running / loading it. Looks like the cam comes online, then it crashes. I did a fresh clone of the repo just to make sure there wouldn't be any odd things with it.

Hey,
very nice project!
I was able to bring it to run on xorg (on another laptop), but not on wayland. I am seeing this error:
INFO: Created TensorFlow Lite XNNPACK delegate for CPU.
qt.qpa.xcb: could not connect to display :1.0
qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "/path/build/sources/bgrm/.venv/lib/python3.9/site-packages/cv2/qt/plugins" even though it was found.
This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.
Available platform plugins are: xcb.
I tried setting DISPLAY to other values (e.g. WAYLAND_DISPAY). Could these envvars be relevant?
QT_QPA_PLATFORM=wayland
QT_WAYLAND_DISABLE_WINDOWDECORATION=1
Is it even supposed to run on wayland?
bgrm.sh: line 15: .venv/bin/activate: No such file or directory
bgrm.sh: line 16: python3.9: command not found
bgrm.sh: line 20: deactivate: command not found
packgaged & installed using PKGBUILD from AUR:
https://aur.archlinux.org/cgit/aur.git/tree/PKGBUILD?h=bgrm-git
In the past Ive had great success in compiling binaries from python scripts using nuitka.
This would be great as it will help to get rid of any python dependencies.
Waiting on mediapipe to have a 3.11 version

A few weeks ago, I was able to get this running after testing out some other solutions, like linux-fake-webcam; however, it would work on zoom, but not teams, which was my target application. Now I'm not getting it to work at all. Any help would be much appreciated.

Having issues currently with python 3.10 and installing the required packages via pip in the virtualenv.
Currently working on a fix
I cannot use pip, as the system-wide Python installation is managed by the system package manager:
❯ pip install bgrm
error: externally-managed-environment
× This environment is externally managed
╰─> To install Python packages system-wide, try 'pacman -S
python-xyz', where xyz is the package you are trying to
install.
If you wish to install a non-Arch-packaged Python package,
create a virtual environment using 'python -m venv path/to/venv'.
Then use path/to/venv/bin/python and path/to/venv/bin/pip.
If you wish to install a non-Arch packaged Python application,
it may be easiest to use 'pipx install xyz', which will manage a
virtual environment for you. Make sure you have python-pipx
installed via pacman.
note: If you believe this is a mistake, please contact your Python installation or OS distribution provider. You can override this, at the risk of breaking your Python installation or OS, by passing --break-system-packages.
hint: See PEP 668 for the detailed specification.
which is fine, but I cannot even use pipx as it doesn't recognize any application in the package:
❯ pipx install bgrm
Note: Dependent package 'numpy' contains 3 apps
- f2py
- f2py3
- f2py3.11
Note: Dependent package 'fonttools' contains 4 apps
- fonttools
- pyftmerge
- pyftsubset
- ttx
No apps associated with package bgrm. Try again with '--include-deps' to include apps of dependent packages, which are listed
above. If you are attempting to install a library, pipx should not be used. Consider using pip or a similar tool instead.
I'm not sure how pipx recognizes applications inside a package.
