使用QMediaPlayer和QVideoWidget
QHBoxLayout *m_layout=newQHBoxLayout(this);
QMediaPlayer *m_player = new QMediaPlayer(this); m_player->setMedia(QUrl::fromLocalFile(QString::fromLocal8Bit("d:/QtTest/111.mp4"))); QVideoWidget *m_videoW = new QVideoWidget(this); m_layout->addWidget(m_videoW); this->setLayout(m_layout); m_player->setVideoOutput(m_videoW); m_videoW->show(); m_player->play(); 代码写起来很简单,编译也能通过,但是运行就会出错DirectShowPlayerService::doRender: Unresolved error code 0x80040266
如果文件路径不对或者文件名是中文的,则会显示如下错误:
DirectShowPlayerService::doSetUrlSource: Unresolved error code 0x80004005 ()
网上查了下,
Qt 中的多媒体播放,底层是使用DirectShowPlayerService,所以安装一个DirectShow解码器,例如LAV Filters,就可以解决运行出错问题 相关帖子 http://bbs.csdn.NET/topics/391040873 https://github.com/qyvlik/Flat.qml/issues/4
