How Youtube HTML5 Audio+Video Streaming Works - by Nick Vogt

How YouTube Streams Video & Audio

Posted Nov 20, 2014 by Nick Vogt

This is a technical post on how the YouTube player works, including the kinds of http requests it makes and how it streams video and audio. This information was researched with the HTML5 player, but may be applicable to the Flash player as well. The HTML5 player uses JavaScript and is the default player for Chrome and newer Internet Explorer.

Get YouTube Video Info

When the YouTube video player is started, either on a youtube.com page or an embed, it first sends a request to http://www.youtube.com/get_video_info with about 13 query string parameters. These parameters contain information such as the video ID, the player width/height, and what host is requesting the video.
