Attaching a QVideoWidget to a QMediaPlayer or QCamera allows it to display the video or image output of that object.
player = new QMediaPlayer; player->setSource(QUrl("http://example.com/myclip1.mp4")); videoWidget = new QVideoWidget; player->setVideoOutput(videoWidget); videoWidget->show(); player->play();
Note: Only a single display output can be attached to a media object at one time.
See also QCamera, QMediaPlayer, and QGraphicsVideoItem.
how video is scaled with respect to its aspect ratio.
Access functions:
Qt::AspectRatioMode | aspectRatioMode() const |
void | setAspectRatioMode(Qt::AspectRatioMode mode) |
Notifier signal:
void | aspectRatioModeChanged(Qt::AspectRatioMode mode) |
This property holds whether video display is confined to a window or is fullScreen.
Access functions:
bool | isFullScreen() const |
void | setFullScreen(bool fullScreen) |
Notifier signal:
void | fullScreenChanged(bool fullScreen) |
Constructs a new video widget.
The parent is passed to QWidget.
[signal]
void QVideoWidget::fullScreenChanged(bool fullScreen)
Signals that the fullScreen mode of a video widget has changed.
Note: Notifier signal for property fullScreen.
See also isFullScreen().
