I wanted a way to share my video with my friends in a Discord call. Lacking a proper webcam, I needed some other way to capture myself on video. Fortunately, I happened to have a Raspberry Pi 4 and a camera module. Initially, I thought maybe I could just connect a USB cable directly between my Raspberry Pi and my computer and have my computer recognize the Pi as a camera with some software. A quick google search helped me realize this is not such a good idea as connecting devices together in this way can damage the connected devices. A special cable typically labeled as a USB bridging cable would be required for this to work and since I am trying to avoid spending money, I needed another solution.
