@SGaist Hi,
I am using Qt version 6.5.0,
on Windows,
and to open fullscreen I am using the following code:

void VideoWidget::mouseDoubleClickEvent(QMouseEvent *event) { setFullScreen(!isFullScreen()); event->accept(); }

VideoWidget is just a derived class from QVideoWidget

@jsulm Okay. I am truly sorry for this, but apparently what I was looking for was showMaximized(). Thank you for the help.

@Saviz

#include <QApplication> #include <QMouseEvent> #include <QVideoWidget> class HoverVideoWidget : public QVideoWidget { public: HoverVideoWidget(QWidget *parent = nullptr) : QVideoWidget(parent) { setMouseTracking(true); // Enable mouse tracking to get hover events } protected: void enterEvent(QEvent *event) override { // Called when the mouse enters the widget setStyleSheet("background-color: lightblue;"); // Set the background color to light blue } void leaveEvent(QEvent *event) override { // Called when the mouse leaves the widget setStyleSheet(""); // Reset the background color to default } }; int main(int argc, char *argv[]) { QApplication app(argc, argv); HoverVideoWidget player; player.show(); return app.exec(); }

@Christian-Ehrlicher
in the same strange way, i have an void :

void QtVsPlayer::FullScr() { if (QtVsPlayer::isFullScreen()) { QtVsPlayer::showNormal(); this->ui->menubar->setVisible(true); if (!Zoomed) this->ui->statusbar->setVisible(true); } else { QtVsPlayer::showFullScreen(); this->ui->menubar->setVisible(false); this->ui->statusbar->setVisible(false); } return; }

this void work, i have fullscreen video.
now in mousemove event i have

if (!this->ui->actionMasquer_les_controles->isChecked() and WVideoCtrls->isHidden() and this->ui->actionAuto_hide_controls->isChecked()) { if(!Zoomed and QtVsPlayer::isFullScreen() == false) ui->statusbar->setVisible(true); WVideoCtrls->show(); WVideoCtrls->activateWindow(); WVideoCtrls->raise(); this->centralWidget()->lower(); this->centralWidget()->stackUnder(WVideoCtrls); } if (QtVsPlayer::cursor() == Qt::BlankCursor) { QtVsPlayer::unsetCursor(); } return;

the goal is to display videocontrols, like play, pause and so on, but not the status bar in full screen, but it is shown, zoomed is false but isfullscreen is no such value

@jsulm In Qt Creator and in VS 2022 as well.

EDIT: I found the problem... QAbstractVideoSurface has been replaced by the QVideoSink class in Qt6:
https://doc.qt.io/qt-6/qtmultimedia-changes-qt6.html

EDIT2: I think i will open two different topic since I found different "bug?"

Windows is running in a Virtual Machine (KVM) with Linux as its host, and the macOS is a Mac Mini Classic at MacInCloud.

@SGaist No. Both computers have same codec set.

Great !

The please mark the thread as solved using the "Topic Tools" button or the three doted menu beside the answer you deem correct so that other forum users may know a solution has been found :-)

@sgaist The problem was the QGuiApplication in my main.cpp , i turned it to QApplication and it works fine.

And lastly what should i do to use my applicationwindow as my videowidget. I want my video to play on my app like normal mediaplayers, not to open another window for it. Thanks for your kind effort.

@magicstar I have the same problem. Have you find a solution ?

@onurcevik Did you ever figure the solution for this? Working on it now

thank you for the tip, I will try this in another project since I currently have a lot of problems getting qmediaplayer or qcamera working on the RaspberryPi. I wrote my code on amd64 on which everything worked fine but on the actual device (RPi) a LOT of problems came in (qt-gstreamer-v4l2-bcm2835-v4l2,MMAL, w.t.h.) but thats worth another thread.

Don't think this is solved, uninstalling gst-plugins-vaapi is a workaround at best.

Bug:
Qt Multimedia GStreamer backend doesn't support HW-accelerated video decoding
https://bugreports.qt.io/browse/QTBUG-23761

Thanks @jsulm

I am assuming that problem is in video drivers, I use fbdev by default (/etc/X11/xorg.conf)

The same situation with HTML5 video

It will be a good place to start- see if all gstreamer plugins are installed in your device. You can also try ldd and make sure no links are broken.

@Lazar-Urosevic Yes, you can have two QVideoWidgets at the same time. Why should one of them block? And why not just try it?
