详细描述
The QMediaContainerControl class provides access to the output container format of a QMediaService
If a QMediaService supports writing encoded data it will implement QMediaContainerControl. This control provides information about the output containers supported by a media service and allows one to be selected as the current output containers.
The functionality provided by this control is exposed to application code through the QMediaRecorder class.
The interface name of QMediaContainerControl is org.qt-project.qt.mediacontainercontrol/5.0 as defined in QMediaContainerControl_iid.
参见 QMediaService::requestControl() and QMediaRecorder.
