It works perfectly on your laptop. You decide to add a \"Video Call\" button. You copy some code from a tutorial, run it on localhost, and it works! You see your own face in two tabs. You feel unstoppable.\u003c\/p\u003e\u003cp\u003eThen, you send the link to a friend. They click the button. \u003cb\u003eBlack screen.\u003c\/b\u003e\u003c\/p\u003e\u003cp\u003eYou try again with a colleague on a corporate network. \u003cb\u003eConnection failed.\u003c\/b\u003e\u003c\/p\u003e\u003cp\u003eYou try to stream a movie to three friends at once. \u003cb\u003eYour browser crashes.\u003c\/b\u003e\u003c\/p\u003e\u003cp\u003eThis is the \"WebRTC Wall\" that every developer hits. The tutorials don't tell you about the aggressive corporate firewalls that block your packets. They don't warn you that a mesh network collapses after four users. They don't explain why your audio drifts out of sync with your video.\u003c\/p\u003e\u003cp\u003eI wrote this book to help you break through that wall. We will leave the safety of localhost behind and tackle the harsh reality of the public internet. We will hunt down the packet loss, conquer the NAT routers, and build a system that doesn't just work in a demo-it works in the real world.\u003c\/p\u003e\u003cb\u003eWhat's Inside\u003c\/b\u003e\u003cp\u003eThis book is packed with practical, architectural knowledge.
