Same Issue on Snap Camera  1.14.0 + M1 Mackbook BigSur 11.6, is there any solution?

Same problem using Canvas Studio.  Once I am ready to record, although I have selected the Snap camera, there is not a video image in the little window.

I have the same on Intel based Big Sur, where it is necessary to run the following command on the application in question to make the virtual camera work.:

sudo codesign --remove-signature /Applications/<your app name>

So for Microsoft Teams it was:

sudo codesign --remove-signature /Applications/Microsoft\ Teams.app

Be careful doing this with applications you don't fully trust as it removes the signature that proves it came from the original author, but as long as you know the application is legit, it should be safe to do this. Anyway this is what got it working for me.

This is harder for system applications such as FaceTime which are on the read-only system volume. I've simply not bothered with those and would advise you do the same but suppose the following should work:

# Boot into recovery mode by holding CMD-R while booting
# Then open a terminal window
csrutil disable
mount -uw /
sudo codesign --remove-signature /System/Applications/FaceTime.app
csrutil enable
# reboot

Feel free to post your results if you try this. Again, I've not yet bothered to try, as this will probably get overwritten as OS patches come through.

Behind the scenes perhaps the virtual camera driver is not properly signed and that's why only non-signed applications can use the virtual camera device? Really just a rough guess.

The snap camera needs an update. Hasn't been updated in years.
