The QVideoSink class can be used to retrieve video data on a frame by frame basis from Qt Multimedia.
QVideoSink can operate in two modes. In the first mode, it can render the video stream to a native window of the underlying windowing system. In the other mode, it will provide individual video frames to the application developer through the videoFrameChanged() signal.
QVideoFrame objects can consume a significant amount of memory or system resources and should thus not be held for longer than required by the application.
