Run script when virtual camera is turned on

I know that using the v4l2loopback it is possible to create a virtual webcam or video device, which we can feed by sending streams using tools like ffmpeg.
It would be very nice to run a script automatically when the virtual webcam is switched on by an application which wants to use it.
In fact the script may run ffmpeg automatically to feed the virtual webcam each time it is switched on, instead of having to feed it manually each time.
Is this possible? What do you think?

You should be able to useinotifywait -e open virtual_webcam.dev, wherevirtual_webcam.devshould be path to the device file. Alternatively, you may want to use-e accessinstead of-e open. Since command exits on one-shot basis, so you may want to wrap this into awhile ...do...doneloop. Let me know if this helps or answers your question, and if it does I'll turn that into proper answer.
