Sorry to hijack this, but adding YUV support to QImage (or anywhere in Qt, really) would be a welcome addition for those of is wanting to capture images from video devices. I keep having to code my own YUV decoder for whatever frames I need to support (Currently, NV21, BGR32, though in the past YUV420). I'm sure the trolls could do a better job at it than I. Having them supported would be a boon to anyone using QVideoFilterRunnable, QAbstractVideoFilter, QVideoProbe classes.
