CodePudding user response：

You are probably looking for a QVideoSink: https://doc-snapshots.qt.io/qt6-dev/qvideosink.html.

The QVideoSink class can be used to retrieve video data on a frame by frame basis from Qt Multimedia.

It is supposed to be set on the QMediaCaptureSession: https://doc-snapshots.qt.io/qt6-dev/qmediacapturesession.html#setVideoSink.

For Qt5 you have QAbstractVideoSurface https://doc.qt.io/qt-5/qabstractvideosurface.html or QVideoProbe https://doc.qt.io/qt-5/qvideoprobe.html.
