Detailed Description

To enable Qt Multimedia in a project, add this directive into your C++ files:

 #include <QtMultimedia>

Using the Module

Using a Qt module requires linking against the module library, either directly or through other dependencies. Several build tools have dedicated support for this, including CMake and qmake.

Building with CMake

Use the find_package() command to locate the needed module components in the Qt6 package:

 find_package(Qt6 COMPONENTS Multimedia REQUIRED)
 target_link_libraries(mytarget PRIVATE Qt6::Multimedia)
