Hi, thanks for making this, it would be very useful to use it in Teams! <p dir="au

It's probably possible to do. Basically in the main loop: <div class="snippet-

Huh, I didn't know that. I'm on Arch too, and I didn't realize it! Added it to the list.

As for the other issue. I see you have python3.9, so that shouldn't be the issue.
Ah I know what it is. You didn't provide a replacement background, and I didn't properly implement the function overloading.

I think I can fix that

Should be fixed now. Tested with and without bg argument. Basically combined:

    def getFrame(self):
        _success, frame = self._vidFeed.read()
        noBgFrame = self._segmentor.removeBG(
            frame, self._settings.fillColor,
            threshold = self._settings.rmThresh
        )
        return (frame, noBgFrame)
    
    def getFrame(self, bgImg):
        _success, frame = self._vidFeed.read()
        noBgFrame = self._segmentor.removeBG(
            frame, bgImg,
            threshold = self._settings.rmThresh
        )
        return (frame, noBgFrame)

which isn't correct because that just gets rid of the first one into:

    def getFrame(self, bgImg = None):
        _success, frame = self._vidFeed.read()

        if shape(bgImg) == ():
            noBgFrame = self._segmentor.removeBG(
                frame, self._settings.fillColor,
                threshold = self._settings.rmThresh
            )
        else:
            noBgFrame = self._segmentor.removeBG(
                frame, bgImg,
                threshold = self._settings.rmThresh
            )
        return (frame, noBgFrame)

Thanks for the quick fix!

By the way, an unrelated idea: do you think it could be possible to implement the "blur background" functionality in this program or would that be off-scope?

If it is, then perhaps we could provide an example of how to pass a still blurred image of the background directly to bgrm, using convert $(shot of current bg) -blur 0x7 "image to be passed to bgrm" for example

It's probably possible to do.
Basically in the main loop:

# Loop over feed
while True:
     # Get cam feed
     if settings.bgImg == '':
         frame, noBgFrame = cam.getFrame()
     else:
         frame, noBgFrame = cam.getFrame(bgImg)
     
     # Write to virtual camera
     virtCam.write(cvtColor(noBgFrame, COLOR_BGR2YUV_I420))

     # Display
     stackFrame = cam.stackFrames(frame, noBgFrame)
     if not cam.display(stackFrame):
         break

In between the frame, noBgFrame setting and the virtCam write, you'd insert something like (i.e. not exactly this):

if settings.blur:
    background = frame - noBgFrame
    blurred = GausianBlur(background, settings.blurAmount)
    noBgFrame += blurred

And of course make sure to run with no background provided
