           Summary: [BlackBerry] Seek calls are being unnecessarily
                    delayed
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Other
        OS/Version: Other

There is a problem with the way the m_userDrivenSeekTimer is implemented. When MediaPlayerPrivate::seek() is called, there is always a 100ms delay even if the timer is not running. The timer is supposed to space out (i.e. throttle) repeated seeks that come in too soon after a previous seek, but currently it is slowing down even single seeks and seeks that come in with adequate delay after a previous seek. I fixed this in my patch by improving the way the timer fired function is called.

I would like to propose not including a layout test with this fix. Doing timing tests for 100ms delays is tricky from Javascript, and I don't think the benefit of such a test outweighs the extra time it would take to develop one. The test would also be a problem to maintain as it may give different results over different runs and across different target hardware.
