Trying to play video with qmediaplayer and qvideowidget

Mistrale

Hi,

Im trying to play a video with a QMediaPlayer and a QVideoWidget. I have just a MainWindow with member variables :
QVideoWidget *_video;
QMediaPlaplyer *_player;
QMediaPlaylist *_playlist;

and this in the mainwindow.cpp :

MainWindow::MainWindow(QWidget *parent) :
QMainWindow(parent),
ui(new Ui::MainWindow)
{
ui->setupUi(this);

_player = new QMediaPlayer(this);
_video = new QVideoWidget(this);
_playlist = new QMediaPlaylist(this);

QUrl    url = QUrl::fromLocalFile("C:\Users\*****\Downloads\Despicable Me (2010) [1080p]\test.mp4");
_playlist->addMedia(url);
std::cout << "C'est valide " << url.isValid() << std::endl;
_playlist->setCurrentIndex(1);
_player->setPlaylist(_playlist);
_player->setVideoOutput(_video);
_video->show();
_player->play();

// _test = new QWidget(this);
// _test->setStyleSheet("background: blue;");
setCentralWidget(_video);
}

When i try to display a simple QWidget _test with a blue background it displays it, but it doesnt work with the QVideoWidget. The url is valid and I just want to play the video.

Does anyone have a suggestion ?

Hi,

Your path is wrong, either use double backslashes to escape the slash properly or do it the Qt way and use forward slashes.

Indeed it works, I thought it was okey with the QUrl isValid returning true.

Thank you !

A valid URL doesn't mean that it points to something valid ;)

You're welcome !
