Detailed Description#
The QVideoSink class can be used to retrieve video data on a frame by frame basis from Qt Multimedia.
QVideoSink will provide individual video frames to the application developer through the videoFrameChanged() signal.
The video frame can then be used to read out the data of those frames and handle them further. When using QPainter, the QVideoFrame can be drawing using the paint() method in QVideoSink .
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.
