我是一家创新的Qt方案家,试图使用Qt phonon工具。
我在网上辅导的帮助下制定了这一方案。 我得以在我的节目中装上录像带,但录像带的规模很小。 我用我非常贫乏的Qt知识,试图增加视频的规模。 我的守则是:
simpleplayer::simpleplayer(QWidget *parent) : QMainWindow(parent)
{
Phonon::VideoPlayer *videoPlayer = new Phonon::VideoPlayer(Phonon::VideoCategory, this);
videoPlayer->play(Phonon::MediaSource("/home/sabbir/Downloads/heli2.avi"));
}
我用了博士学位,因此我不敢肯定,你的录像将用<密码>播放。 Phon:VideoPlayer
