There’s an entry on the W3C blog about the state of HTML5 video. The most significant point is that “we still don’t have a baseline video codec for HTML5.” Without that, it’s silly to talk about HTML5 as an alternative to Flash or any other kind of video presentation.

Both codecs have patent issues, limiting the opportunities for third parties to fill in the gap. Both have enthusiastic advocates.
