QVideoWidget ¶

概要 ¶

详细描述 ¶

Attaching a QVideoWidget 到 QMediaObject allows it to display the video or image output of that media object. A QVideoWidget is attached to media object by passing a pointer to the QMediaObject in its constructor, and detached by destroying the QVideoWidget .

player = new QMediaPlayer;
playlist = new QMediaPlaylist(player);
playlist->addMedia(QUrl("http://example.com/myclip1.mp4"));
playlist->addMedia(QUrl("http://example.com/myclip2.mp4"));
videoWidget = new QVideoWidget;
player->setVideoOutput(videoWidget);
videoWidget->show();
playlist->setCurrentIndex(1);
player->play();
											

注意 ：每次只可以把单个显示输出附加到媒体对象。
