|
52 \brief The QMediaRecorderControl class provides access to the recording |
|
53 functionality of a QMediaService. |
|
54 |
|
55 If a QMediaService can record media it will implement QMediaRecorderControl. |
|
56 This control provides a means to set the \l {outputLocation()}{output location}, |
|
57 and \l {record()}{start}, \l {pause()}{pause} and \l {stop()}{stop} |
|
58 recording. It also provides feedback on the \l {duration()}{duration} |
|
59 of the recording. |
|
60 |
|
61 The functionality provided by this control is exposed to application |
|
62 code through the QMediaRecorder class. |
|
63 |
|
64 The interface name of QMediaRecorderControl is \c com.nokia.Qt.QMediaRecorderControl/1.0 as |
|
65 defined in QMediaRecorderControl_iid. |
