Classes are available for both high and low level to play and manipulate video data. Some of these classes also overlap with the audio and camera classes.

The QMediaPlayer class can be used to decode a video file and display it using QVideoWidget, QGraphicsVideoItem, or a custom class.

CsMultimedia also offers a number of low level classes to make handling video frames a bit easier. These classes are primarily used when writing code that processes video or camera frames. For example, detecting barcodes, applying a fancy vignette effect, or displaying a video in a special way that is otherwise unsupported.
