Description Eric Carlson 2011-04-29 14:06:23 PDT
At some point in the past, the spec required a seek to time 0 once metadata is loaded. The spec text has been changed to say:

   If either the media resource or the address of the current 
   media resource indicate a particular start time, then set 
   the initial playback position to that time, seek to that time, 
   and let jumped be true. Ignore any resulting exceptions 
   (if the position is out of range, it is effectively ignored).

WebKit doesn't support starting at an offset, so we should not force a seek to time 0.

So this is not at all visible from javascript (that surprises me).

It isn't visible because it is a noop - the media file has just been opened and it is no playing, so "seeking" to time zero does nothing.

OK.  Would be nice to say that in the ChagneLog. :)
