By the way, were there considerations on patents on this ? For
example, did Apple patent any of their technique of cutting chunks or
maybe on the encoder side.

Also is javascript a requirement for this ? Or just pointing to a
proper URL would be enough for the browser to know it's adaptative and
handle it silently ?
