In a new post to his blog today Gonzalo Ayuso talks about video streaming and PHP. Well, okay, not so much using PHP for playing the video, more for the security and streaming around the streaming feeds.

For example we want to show videos only to registered users based on our authentication system. Imagine we're using sessions for validate users. That's means we cannot put the media in a public folder and point our media player to those files. We can obfuscate the file name but it'll remain public. In this small tutorial We're going to see how to implement it with PHP.

Since the video stream he wants to deal with is a live one (and not a single video file that can be read all at once) he shows how to use the output buffering functions in PHP to output small chunks of the data at a time with the correct headers attached.
