Add mp4 video

[Rumeysa_135]

Hello, I want to ask you something. I made a video design. I want to play this video on the interface screen I created in Qt widget Applications. But I want to do it without using keys like play, pause. As soon as I run the interface, I want the video to appear directly on the screen. How can ı do that?

Hi,

You can use a QVideoWidget and start the video from your code.

I looked at the page you said and did it, but the video did not appear on the screen. The blank main window just popped up. Why did this happen?

Hard to say without seeing your code...

MainWindow::MainWindow(QWidget parent)
: QMainWindow(parent)
, ui(new Ui::MainWindow)
{
ui->setupUi(this);
QMediaPlayer player = new QMediaPlayer;
QUrl videoUrl = QUrl::fromLocalFile("‪C:/Users/Desktop/video.mp4");
QMediaContent videoMedia(videoUrl);
player->setMedia(videoMedia);
QVideoWidget* videoWidget = new QVideoWidget;
videoWidget->setMinimumWidth(640);
videoWidget->setMinimumHeight(360);
player->setVideoOutput(videoWidget);
videoWidget->setGeometry(QRect(10, 10, 640, 360));
player->play();

}

@Rumeysa_135 As far as I can see you're neither showing videoWidget nor putting it into a layout, so it is not shown. And as soon as you call show on it it will be shown as stand alone widget because it does not have a parent and is not added to any layout.

DirectShowPlayerService::doRender: Unresolved error code 0x80040266 () How can i fix this error?

[SGaist]

First thing, did you address the issues pointed in your code ?

Next, can you properly render that file on your system ?

Then, which version of Qt are you using ?
The latest 6.5 should use the ffmpeg backend.

Please try on .avi file. .mp4 file is not support for windows.
kindly load .avi file. Then the video will play.
Like,
QUrl videoUrl = QUrl::fromLocalFile("‪C:/Users/Desktop/video.avi");
