           Summary: [gtk] QoS implementation could be better
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: PC
               URL: http://people.freedesktop.org/~company/stuff/video-dem
        OS/Version: Mac OS X 10.5
            Status: UNCONFIRMED
          Severity: Normal
          Priority: P2
         Component: Media Elements
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: otte at gnome.org

In the linked web page, multiple videos are displayed on a canvas. Usually this
takes too much CPU to cmfortably play back and the GStreamer QoS framework
kicks in. When this happens, some videos aren't updated for multiple seconds
while others continue playing fine. It would be preferrable if all videos get
slowed down by the same amount.

About the demo:
- It's a page I've done by myself
- I can easily add more videos if your CPU is too fast and oS doesn't kick in
- I have no idea if it works on other media players (It displays movie
trailers, which should be H264, so Ihope so)
- the page is self-contained, so one could attach it here if that's considered
a better idea?
