RE: HTML5 Last Call May 2011 & DASH/Adaptive Streaming

I see a certain value for offering a baseline adaptive streaming client as part of the html5 standard. At the end, if all the vendors will eventually converge to what DASH spec offers, a baseline client would only accelerate this convergence. A common client across different browsers and platforms will make life easier for many of us.

As long as the wg also includes provisions for parameterization of the baseline client through an API (scripting or something else), one can still customize the behavior of the player. Making all this codec independent is of course highly desirable.
