           Summary: HTML5 media elements do not fire seeking of waiting
                    events
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: PC
        OS/Version: Mac OS X 10.5
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: WebCore Misc.
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: ajwong at chromium.org


The HTMLMediaElement implementation of SetReadyState makes it impossible to
correctly fire waiting, seeking, and seeked events based purely on the changes
in ready state.

There are two separate issues:

  (1) 4.8.10.10 step 8 is not done quite right; waiting is fired after seeking.
  (2) The seekedEvent is not guaranteed to fire for eack seekingEvent.

Fixing #1 should be as simple as moving the code block for waiting up above the
seeking event.

Fixing #2 required an extra status variable to track when a seekingEvent has
started, and thus a seekedEvent should be fired.

Changes will also need to be made to the the MediaPlayerQT (and likely other
ports) to support lowering the ready state to HAVE_METADATA on seek.
