Turning YouTube Into Cloud Storage
How I made a YouTube file media storage using C++ and a few libraries. You can view my repository here: https://github.com/PulseBeat02/yt-med... Encoded Video: • output Here is the Wirehair O(N) fountain codec repository: https://github.com/catid/wirehair For those who want to learn more, I recommend taking a look into CRC flavors, Wirehair code, and video compression algorithms. I tried to give a brief explanation, but in the real-world, they are much more complex. Animations were made using a combination of Manim and DaVinci Resolve https://github.com/3b1b/manim https://www.blackmagicdesign.com/prod...
