How Netflix & YouTube Actually Stream Videos #coding #programming #javascript #reactjs

You think Netflix or YouTube just plays an MP4 file?

That’s NOT how real video streaming works.

In this video, I explain how modern streaming systems actually work:

✔ Why MP4 is not used directly
✔ How videos are processed after upload
✔ Video chunking (breaking video into small parts)
✔ Multiple quality versions (240p, 360p, 720p)
✔ HLS streaming system
✔ Master file controlling playback
✔ How instant seeking works

Example:
10-minute video → split into small chunks → streamed dynamically

This gives:
• Better performance
• Adaptive quality
• More security
• Faster loading

This is how platforms like Netflix, YouTube, and Prime Video work.
