Multimedia Backend Development

Information for implementing a new multimedia backend.

Overview

A multimedia backend provides the glue between platform-specific libraries, and Qt Multimedia. In some cases the available cross-platform Multimedia APIs or implementations are not sufficient, or not immediately available on a certain platform. Alternatively, the multimedia implementation on a platform might expose certain extra properties or functionality that other platforms do not, or a finer degree of control might be possible. For these cases, it is possible to use extended controls directly.
