Detailed Description

The QCustomAudioRoleControl class provides control over the audio role of a media object.

If a QMediaService supports audio roles it may implement QCustomAudioRoleControl in order to provide access to roles unknown to Qt.

The functionality provided by this control is exposed to application code through the QMediaPlayer class.

The interface name of QCustomAudioRoleControl is org.qt-project.qt.customaudiorolecontrol/5.11 as defined in QCustomAudioRoleControl_iid.

See also QMediaService::requestControl() and QMediaPlayer.
