Sotaro and I took a look at a profile of video playback on windows. It had a bunch of reasonably bad stuff: - lots of page faults caused by new allocations - quite a bit of time being spent in color conversion - general cairo drawing overhead

Can we use more CPU cores to do colour conversion and scaling?
(In reply to Anthony Jones (:kentuckyfriedtakahe, :k17e) from comment #6) > Can we use more CPU cores to do colour conversion and scaling? Yes, but there's lower hanging fruit first. The color conversion code that we're using is not very good so we should fix that first (see bug 1254872)
