Qt Multimedia
summary
Qt Multimedia provides both low-level audio/video primitives and high-level, portable APIs for playback, radio, recording and camera API control; it exposes video surface / video buffer / frame objects so apps can grab hardware-accelerated frames or render into QML via a graphics video item. Backends use existing frameworks (GStreamer, DirectShow/QuickTime where available). Example: a panorama proof‑of‑concept adds sensors and a draggable preview with a few QML lines and runs on Qt Mobility 1.1 as part of the mobility package.
