@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

I have the same issue. It's soo slow with rtsp and buggy.

I have the same problem on Ubuntu 22.04 with Qt 6.4.2. I have (re)opened a bug report.

@jsulm In Qt Creator and in VS 2022 as well. Qt Creator: VS 2022: 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 QAbstractVideoSurface has been replaced by the QVideoSink class in Qt6: https://doc.qt.io/qt-6/qtmultimedia-changes-qt6.html EDIT2: I think i will open two different topic since I found different "bug?"

The problem was in the Windows firewall. I still don't understand why this was affecting the sound, but disabling the firewall did the trick.

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 I'll try to cross compile qt again and let you know the error . Meanwhile can you please share any link where i can get the procedure about how to cross compile qt for zynq mpsoc devices. Thanx.

@Pablo-J-Rogina thanks. Just looked into it. As the docs for QNetworkConfiguration state: QNetworkConfiguration encapsulates a single access point or service network. In most cases a single access point configuration can be mapped to one network interface. I deduce from that, that any call to QMediaPlayer::setNetworkConfigurations(QList<QNetworkConfiguration>) will not fix my problem. In fact, I gather from the information, that QNetworkConfiguration deals more with hardware-side networking & routing configurations than it does with specifics for transmission protocols. This notion is strengthened by the fact, that there is no accessible public members for QNetworkConfiguration and the only available constructors are copy and default. Therefore, the only way accessible way to provide valid values to setNetworkConfigurations is by filtering QNetworkConfigurationManager::allConfigurations()). Then again, this method produces a list dependent on the host system, which indicates hardware specific settings. Still, I got curious while reading the desciption for QNetworkConfiguration::ServiceSpecificPurpose, which states: The configuration can be used for operator specific services (e.g. receiving MMS messages or content **streaming**). For experimental purposes I filtered all available configurations of that type, which again didn't change anything for me. (Also, be sure to check out my latest edit up top, if you care for more info)

It seems remarkable to me that the QMediaPlayer can know whether I'm playing back audio with 1, 2, or more channels, but I cannot get that information from it, but I guess that's just the way it is? It seems like some people can get this to work, and others can't, so I wonder if this is another issue of platform differences? (For reference, this is playback either via a wired connection to an MFi device, or directly on an iPad/iPhone, so iOS under the hood.) Anyway, I've given up on displaying mono/stereo channel information in our implementation. (The player will fail to play back audio with three or more channels, so I can at least flag that. It'd be nice to label, but it's not required.) I'll report a bug if I get the time at some point.

Hey, Sorry for late answer. Yes everything seemed fine. No error report at least. But I'm guessing that this might not actually be linked with this topic anymore. So I'll just look into this issue on my own from there. Anyway, thanks a lot for the support ! Best regards, TomHat

Hi @SGaist , Thanks for your response. Just wanted to know for sure if there was a way to do it with Qt itself. Will start looking at other options. Thanks.

Thank you for the greeting. The file is working fine with the other players (VLC, Windows 10 player).

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

Here is pretty much the commands I use to deploy the app: qmake videoplayer/videoplayer.pro -o build/MakeFile -r -spec win32-msvc2010 -nocache jom -f Makefile -s windeployqt --release release

Hi @gsharma , I see you solved your problem. I have similar problem. I use qt-5.10 and IP camera. I want to stream with rtsp. Also want to see at QMediaPlayer. Could you please help me. How did you solve problem. Also do you know tutorial about this.

IIRC, the two builds are not using the same backend.

Glad you found out and thanks for the feedback !

You can take a look at that article.

Problem solved. It was bug in Inno setup, which corruped Qt5Multimedia.dll somehow.

[SOLVED] MainWindow::MainWindow(QWidget *parent) : QMainWindow(parent), ui(new Ui::MainWindow) { //… display = new QLabel(this); display->setGeometry(4,4,88,23); display->setText("00:00:00"); //… player = new QMediaPlayer; connect(player, SIGNAL(mediaStatusChanged(QMediaPlayer::MediaStatus)), this, SLOT(playerOnMediaStatusChanged(QMediaPlayer::MediaStatus))); //… timer = new QTimer; timer->setTimerType(Qt::PreciseTimer); connect(timer, SIGNAL(timeout()), this, SLOT(timerSlot())); //… } void MainWindow::playerOnMediaStatusChanged(QMediaPlayer::MediaStatus status) { if (status == QMediaPlayer::BufferedMedia) { pos = -1; //int pos declared on .h file timer->start(1000); } } void MainWindow::timerSlot() { pos = pos + 1; QTime time((pos/3600)%60, (pos/60)%60, pos%60); display->setText(time.toString("hh:mm:ss")); }

[SOLVED] I had to resort to the help of TagLibs library. And since the documentation available how to build this library to make it interact with Qt are very confusing and outdated, I proceeded to make available the library that I managed, with great difficulty, to compile by my hand: http://www.unitscan.org/archives/301 I hope will be usefull

Hi and welcome to devnet ! Thanks for sharing the report link ! It has been marked as solved for Qt 5.7.1. So please mark this thread as solved using the "Topic Tools" button so other forum users may know a solution has been found :)

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

Thank you for tip..I will check it..

@hariny , @onek24 Since this thread was not resolved; the buffer is not open !!! your are missing two lines of code: buffer->open(QIODevice::ReadOnly); buffer->seek(0);

Hi and welcome to devnet, QtMultimedia uses Apple's Media Foundation for it's OS X backend so the format supported depends on what Media Foundation can support. Can you try the same application using the latest version of Qt ?

Hi, Usually, to play sound effect, the QSoundEffect class is used. Wouldn't that fill your need ?
