\brief The QAudioEncoderControl class provides access to the settings of a
|
||||
media service that performs audio encoding.
|
||||
|
||||
If a QMediaService supports encoding audio data it will implement
|
||||
QAudioEncoderControl. This control provides information about the limits
|
||||
of restricted audio encoder options and allows the selection of a set of
|
||||
audio encoder settings as specified in a QAudioEncoderSettings object.
|
||||
|
||||
The functionality provided by this control is exposed to application code through the
|
||||
QMediaRecorder class.
|
||||
|
||||
The interface name of QAudioEncoderControl is \c com.nokia.Qt.QAudioEncoderControl/1.0 as
|
||||
defined in QAudioEncoderControl_iid.
|
||||
|
||||
