           Summary: [queue2] wrong percent-filled estimation during
                    on-disk buffering
    Classification: Desktop
           Product: GStreamer
           Version: git
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: Normal
         Component: gstreamer (core)
        AssignedTo: gstreamer-bugs at lists.sourceforge.net
        ReportedBy: phil at base-art.net
         QAContact: gstreamer-bugs at lists.sourceforge.net
      GNOME target: ---
     GNOME version: ---


It seems that in update_buffering() and if rate estimation is enabled the
rate_time is wrongly calculated in GET_PERCENT() and percent value becomes
wrong too ;)

To reproduce:

gst-launch-0.10 playbin2 flags=0x97
uri="http://chaos.troll.no/~tavestbo/webkit/mediaelement/bunny/big_buck_bunny_480p_surround-fix.avi"

The video window doesn't show up. Using a normal buffering strategy works.
