52 \brief The QVideoRendererControl class provides a control for rendering |
|
53 to a video surface. |
|
54 |
|
55 \ingroup multimedia-serv |
|
56 |
|
57 Using the surface() property of QVideoRendererControl a QAbstractVideoSurface |
|
58 may be set as the video render target of a QMediaService. |
|
59 |
|
60 \code |
|
61 QVideoRendererControl *rendererControl = mediaService->control<QVideoRendererControl *>(); |
|
62 rendererControl->setSurface(myVideoSurface); |
|
63 \endcode |
|
64 |
|
65 QVideoRendererControl is one of number of possible video output controls, |
|
66 in order to receive video it must be made the active video output |
|
67 control by setting the output property of QVideoOutputControl to |
|
68 \l {QVideoOutputControl::RendererOutput}{RendererOutput}. Consequently any |
|
69 QMediaService that implements QVideoRendererControl must also implement |
|
70 QVideoOutputControl. |
|
71 |
|
72 \code |
|
73 QVideoOutputControl *outputControl = mediaService->control<QVideoOutputControl *>(); |
|
74 outputControl->setOutput(QVideoOutputControl::RendererOutput); |
|
75 \endcode |
|
76 |
|
77 The interface name of QVideoRendererControl is \c com.nokia.Qt.QVideoRendererControl/1.0 as |
|
78 defined in QVideoRendererControl_iid. |
