Live webcam video replacement?

Question

Programming

Hello
I need to replace the video from the webcam with the same video, but already changed. What are the ways? It doesn't matter, it can be programs or code (I can write it). I can't find anything like it. Everywhere there is only a replacement for a video (they simply upload it to the program and it is broadcast instead of a webcam). But I need real time

Captures your webcam and replaces it with a pre-saved live video of everything happening.
