[SOLVED] QMediaPlayer plays local videos, but doesn't play remote videos

QtYury

Windows 7 + Qt 5.1.0 mingw
QMediaPlayer plays local videos, but doesn't play remote videos. Local video file is the same as remote one. QMediaPlayer sets status QMediaPlayer::InvalidMedia shortly after start.
Here is the code:
@
int main(int argc, char *argv[])
{
QApplication app(argc, argv);

QWidget wgt;
QMediaPlayer *mediaPlayer = new QMediaPlayer(&wgt, QMediaPlayer::StreamPlayback);
QVideoWidget *videoWidget = new QVideoWidget(&wgt);

QBoxLayout *layout = new QVBoxLayout;
layout->addWidget(videoWidget);

wgt.setLayout(layout);

mediaPlayer->setVideoOutput(videoWidget);
mediaPlayer->setMedia(QUrl("http://mng.ivbn.net/mng/uploads/empty.mp4")); /* DOESN'T WORK! */
//mediaPlayer->setMedia(QUrl::fromLocalFile&#40;"C:/Users/Yury/Downloads/empty.mp4"&#41;&#41;; /* WORKS! */
mediaPlayer->play();

wgt.resize(640, 480);
wgt.show();

return app.exec&#40;&#41;;

}

are you sure you have the QtNetwork module and linked against it?

I have

@
QT += network
@

in my project file. To be completely sure, I've added example http://qt-project.org/doc/qt-5.1/qtnetwork/http.html to my project. The example works fine.

I found that
@
mediaPlayer->currentNetworkConfiguration()
@

returns empty QNetworkConfiguration. My network connection is ok, and running
@
QNetworkConfigurationManager ncm;
foreach (QNetworkConfiguration nc, ncm.allConfigurations(QNetworkConfiguration::Active))
{
qDebug() << nc.name() << nc.identifier();
}
@

gives me two active connections. But trying to set this active connections to my mediaPlayer fails:
@
mediaPlayer->setNetworkConfigurations(ncm.allConfigurations(QNetworkConfiguration::Active));
qDebug() << mediaPlayer->currentNetworkConfiguration().identifier(); // empty string!
@

The documentation of QMediaPlayer states:
"QNetworkConfiguration QMediaPlayer::currentNetworkConfiguration() const

Returns the current network access point in use. If a default contructed QNetworkConfiguration is returned this feature is not available or that none of the current supplied configurations are in use."

So, I have two possible reasons of my problem.

I tried to play different file formats - mov and ts. It works! Perhaps the problem is related to the codecs in my system.
It takes a lot of time before the video starts, but that's another story )

SOLVED!
