    <thetext>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&apos;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&apos;s a page I&apos;ve done by myself
- I can easily add more videos if your CPU is too fast and oS doesn&apos;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&apos;s considered a better idea?</thetext>

    <thetext>Hey Benjamin,
That&apos;s a nice little example you&apos;ve put together there.

I&apos;m not really involved with Webkit/Gtk at all, but this is a good test for all UAs. I might note that this is a much better test if each of those media items is downloaded and run locally. Forces us to test playback, and not the network. :)</thetext>
