Qt Multimedia C++ Classes
The C++ classes provide more control over the multimedia content than the QML alternatives. If your application is serving complex use cases such as decoding media files, accessing video or audio buffers, use the C++ alternative. For more details about the complex audio, video, and camera use cases supported by the C++ classes, refer to Multimedia Overview.
