详细描述

若 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 类。

The interface name of QMediaContainerControl is org.qt-project.qt.mediacontainercontrol/5.0 作为定义在 QMediaContainerControl_iid .
