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
Traceback (most recent call last):
  File "/usr/lib64/python3.9/runpy.py", line 197, in _run_module_as_main

  File "/usr/lib64/python3.9/runpy.py", line 87, in _run_code
    exec(code, run_globals)

    from bgrm import main
  File "/home/user/Applications/bgrm/bgrm/bgrm.py", line 8, in <module>
    pkg_resources.require("opencv-python<=4.4.0.46")
  File "/usr/lib/python3.9/site-packages/pkg_resources/__init__.py", line 886, in require
    needed = self.resolve(parse_requirements(requirements))
  File "/usr/lib/python3.9/site-packages/pkg_resources/__init__.py", line 772, in resolve
    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!

Hi, I'm having trouble actually getting this set up. I get this error when I try to run the bgrm script:

INFO: Created TensorFlow Lite XNNPACK delegate for CPU. Traceback (most recent call last): File "/usr/lib/python3.9/runpy.py", line 197, in _run_module_as_main return _run_code(code, main_globals, None, File "/usr/lib/python3.9/runpy.py", line 87, in _run_code exec(code, run_globals) File "/home/Desktop/Misc./Software/bgrm/bgrm/main.py", line 4, in main() File "/home/Desktop/Misc./Software/bgrm/bgrm/bgrm.py", line 28, in main formatVirtualCamera(settings, virtCam, cam) File "/home/Desktop/Misc./Software/bgrm/bgrm/bgrm.py", line 66, in formatVirtualCamera ioctl(virtCam, VIDIOC_S_FMT, format) OSError: [Errno 25] Inappropriate ioctl for device

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.

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

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.

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

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?

i get ~6 fps with bgrm and 30 without, my specs are : ❯ neofetch

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.

Hi,

I've committed my changes I've done under Linux Mint to make the process run under user space and install the module permanently.

You might not be interested in merging this code if it does not generalize to Arch but it might be useful for others.

Cheers kata

Reason:

• Now you can pass input/output video files and remove files from them!

Changes:

• New VidFile class based on Cam, but using in/out files instead of file
• Adjust main loop to split into Cam/VirtCam and VidFile paths
• File Mode settings added to cli args
