QVideoWidget使用报错
Qt版本 5.1.0
帮助文档能找到此类 , 但是在程序中引用时就提示此类未声明 , 怎么破?
playlist = new QMediaPlaylist;
playlist->addMedia(QUrl("http://example.com/movie1.mp4"));
playlist->addMedia(QUrl("http://example.com/movie2.mp4"));
playlist->addMedia(QUrl("http://example.com/movie3.mp4"));
playlist->setCurrentIndex(1);
player = new QMediaPlayer;
player->setPlaylist(playlist);
videoWidget = new QVideoWidget;
player->setVideoOutput(videoWidget);
videoWidget->show();
player->play();
