What I am trying to achive is to redirect my camera /dev/video0 with a custom video file.
Desired Reasult:
When opened a application like cheese or websites like jitsi which process the buffer from my camera. Is it possible to use already captured video file as camera input.
Previous attempt:
I followed a answer from this answer but i am getting a error message as
