Detailed Description
If a QMediaService supports encoding video data it will implement QVideoEncoderSettingsControl. This control provides information about the limits of restricted video encoder options and allows the selection of a set of video encoder settings as specified in a QVideoEncoderSettings object.
The functionality provided by this control is exposed to application code through the QMediaRecorder class.
The interface name of QVideoEncoderSettingsControl is org.qt-project.qt.videoencodersettingscontrol/5.0 as defined in QVideoEncoderSettingsControl_iid.
See also QMediaRecorder, QVideoEncoderSettings, and QMediaService::requestControl().
