Site for learning about video codecs on the web

Question

I am interested in learning about the HTML 5 specification as well as different video codecs for use in various browsers (mobile and desktop). So In an effort to learn about as much as I can, I'm starting this post. Please feel free to give any resources you found helpful in this regard.

Thanks!
Thomas

Here's a good one I've been reading. Very in-depth coverage of video and audio codecs/ file formats, and how they relate to the web.
