tushar2madaan/mern-video-streaming ? reverse-engineered prompt

Build me a full video streaming app where people can upload videos, see them processed, and then stream them in the browser.

I want the app to feel like a simple video hosting site, with a clean React frontend and a solid backend that handles uploads, video conversion, and playback. When a video finishes processing, the user should get a real time update so they know it is ready to watch. There should be a main list of videos, a way to view details for each one, and a smooth player experience for the streaming side.

Please set it up as a full stack project with a Node and Express backend, a MongoDB database, and a frontend that looks modern and polished. Use Docker if that helps make the setup easier, and look up current docs online if you need to. Keep the code organized so it is easy to run locally and easy to extend later.
