ENGINEER-MUHAMMAD-SHAHZAIB/VisionShift ? reverse-engineered prompt

Build me a simple Python app that lets me swap a face in a photo, video, or live webcam feed using just one source image and one click.

I want it to be easy to run from a single start script, with a small interface where I can pick a face image, choose a camera or video file, and then preview the result in real time. It should support a live mode for webcam use, plus a normal mode for images and videos. If possible, add a mouth movement option so the face still looks natural, and make sure it works smoothly with GPU acceleration when available, including Windows setups.

Please keep the setup straightforward, load the needed models automatically if they’re missing, and show clear messages if something isn’t installed. Also include basic safety checks so it doesn’t process clearly inappropriate content, and add simple notes reminding users to only use real faces with consent. If you need to check current install or runtime details online, go ahead and look them up.
