Description Bobby Holley (:bholley) 2015-06-16 18:58:26 UTC 
"Update the media controller duration to new duration and run the HTMLMediaElement duration change algorithm."

By my reading, the specs are currently ambiguous as to what happens when the MediaSource.duration gets set to +Infinity. Do we fire durationchange or not?

mediasource-duration-boundaryconditions.html tests that we do, but the HTML5 spec uses +Infinity to denote "unknown duration", and we're only supposed to fire durationchange when the duration changes "to a known value". Should +Infinity have a different meaning when it comes from MediaSource?
