@Cleiton-Bueno Command output: PACKAGECONFIG="gstreamer alsa gstreamer" PACKAGECONFIG_CONFARGS=" -alsa -gstreamer 1.0 -no-feature-openal -no-pulseaudio" PACKAGECONFIG_OPENSSL="openssl" @edit I also discovered that there is no "qmlgl" (qmlgloverlay, qmlglsink, qmlglsrc) in the system which should be provided by gstreamer1.0-plugins-good. I forced to build packet configurated for qt5 by add line in my local.conf: PACKAGECONFIG:append:pn-gstreamer1.0-plugins-good = " qt5" After that I have available qmlglsink and other. I still can't play video directly from file because effect is the same no image. I tried to build pipeline: source: "gst-pipeline: filesrc location=/home/root/dillama_1080p.mp4 ! decodebin name=dec ! videoconvert ! qmlglsink widget" I can't set required pointer to qml widget for qmlglsink. How do it?

@The-Qt-Mayssa both widgets and qml are concerned. For the rest I don't know. You need to do some testing since you have the various systems at hand.

@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

One possible alternative could be to use a Docker container to build your application with a suitably old Ubuntu or maybe a VM which would be even simpler,

@SGaist, yes Qt 6.5

@SGaist Thank you! That should be probably it! I will test it on 6.5.1 when it will be released and report back.

@SGaist Ah, in that case, I'll give it a try. Would that also be the case with QAbstractVideoSurface, or would that one receive further-in frames if more time passes? Processing takes about 250ms per frame on Android right now. I'm working on ways to speed that up, but the processing fps is going to be worse than the video file's fps for some time yet.

@GrecKo It does, but it seems to be a read-only reflection of the viewport set for the video frame objects that are coming through the videoSink. When I attempt to assign to it, I get the QML error: Invalid property assignment: "sourceRect" is a read-only property. The docs do not appear to reflect the fact that sourceRect is read-only. I am using Qt 6.3. Looking at the source for VideoOutput (https://github.com/qt/qtmultimedia/blob/37c2d097eb5dd8671cc752dc920da11d66105905/src/multimediaquick/qquickvideooutput_p.h#L41), we can see that the Q_PROPERTY for sourceRect is read-only in both the 6.3 and dev branches. I have had the thought of attempting to manually set the viewport of the QVideoFrameFormat of the frames coming through the VideoOutput's videoSink, but I haven't created a working solution for that strategy yet.

Which examples are you referring to ?

@iamRahul I figured it out. We need to specify full location path till the file, and specify file type in format. Then it worked for me. if(audioPlaylist.save("file:///C:/MyMusicPlayer/Playlists/global_playlist.m3u","m3u")) { console.log("Playlist Saved") } Adding the filename global_playlist.m3u and format m3u made it working for me.

Solved QString mediafile = playlist->media(n).request().url().toString(); QFileInfo fi(mediafile); reader->setMedia(QUrl::fromLocalFile(fi.absoluteFilePath()));

@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.

[image: 76eb5c40-4e61-4b6b-ae89-0ce60cf6bd0e.png] I have these versions . It does not work when i build directly on raspberry pi .

Then study the gstreamer implementation for example and start from there. The pattern is to have a "session class" that does the work and then provide all the interfaces you support that will be using said session class.

I got the answer . MainWindow.cpp is like that ui->listWidget->setFlow(QListView::LeftToRight); ui->listWidget->setMinimumSize(1050,800); ui->listWidget->setGridSize(QSize(340, 320)); ui->listWidget->setResizeMode(QListView::Adjust); ui->listWidget->setViewMode(QListView::ListMode); ui->listWidget->setWrapping(true); QDir directory = QFileDialog::getExistingDirectory(this, tr("Open Directory"),"/home", QFileDialog::ShowDirsOnly| QFileDialog::DontResolveSymlinks); directory.setNameFilters({"*.mp4" , "*.avi" , "*.flv" , "*.mwv"}); for(const QFileInfo & finfo: directory.entryInfoList()){ QMediaPlayer *mediaPlayer = new QMediaPlayer(); mediaPlayer->setMedia(QUrl::fromLocalFile(finfo.absoluteFilePath())); videoItem = new QGraphicsVideoItem; videoItem->setSize(QSize(300,240)); QGraphicsScene *scene = new QGraphicsScene(this); QGraphicsView *graphicsView = new QGraphicsView(scene); mediaPlayer->setVideoOutput(videoItem); QPushButton *m_playButton = new QPushButton(); m_playButton->setIcon(style()->standardIcon(QStyle::SP_MediaPlay)); connect(m_playButton, &QAbstractButton::clicked, [mediaPlayer]() { switch (mediaPlayer->state()) { case QMediaPlayer::PlayingState: mediaPlayer->pause(); break; default: mediaPlayer->play(); break; } }); connect(mediaPlayer, &QMediaPlayer::stateChanged, [m_playButton, this](QMediaPlayer::State state) { switch(state) { case QMediaPlayer::PlayingState: m_playButton->setIcon(style()->standardIcon(QStyle::SP_MediaPause)); break; default: m_playButton->setIcon(style()->standardIcon(QStyle::SP_MediaPlay)); break; } }); QSlider *m_positionSlider = new QSlider(Qt::Horizontal,this); m_positionSlider->setRange(0,mediaPlayer->duration() / 1000); connect(mediaPlayer, &QMediaPlayer::positionChanged ,[m_positionSlider, this](qint64 position){ m_positionSlider->setValue(position); }); connect(mediaPlayer, &QMediaPlayer::durationChanged ,[m_positionSlider, this](qint64 duration){ m_positionSlider->setRange(0,duration); }); connect(m_positionSlider ,&QAbstractSlider::sliderMoved, [mediaPlayer ,this] (int position){ mediaPlayer->setPosition(position); }); auto item = new QListWidgetItem("", ui->listWidget); auto widget = new QWidget; auto label = new QLabel(finfo.fileName()); auto vb = new QVBoxLayout; QBoxLayout *controlLayout = new QHBoxLayout; controlLayout->setMargin(0); controlLayout->addWidget(m_playButton); controlLayout->addWidget(m_positionSlider); vb->addWidget(label); vb->addWidget(graphicsView); vb->addLayout(controlLayout); widget->setLayout(vb); widget->setMinimumSize(320, 320); ui->listWidget->setItemWidget(item,widget); player.append(mediaPlayer); scene->addItem(videoItem); }
