QMediaPlayer playing very slow or low frame rate.

[Bonty]

Qt Version = Qt 5.15
Development = Linux OS on SOC.

VideoPlayerForm::VideoPlayerForm(QWidget *parent)
    : QDialog(parent)
    , ui(new Ui::VideoPlayerForm)
{
    ui->setupUi(this);
    ui->videoPlayerWidget->setAspectRatioMode(Qt::IgnoreAspectRatio);
    qDebug() << "playing video";
    player = new QMediaPlayer(this);
    player->setVideoOutput(ui->videoPlayerWidget);
    //player->setMedia(QUrl("gst-pipeline: gst-launch-1.0 playbin uri=file:/home/root/video.mkv"));
    player->setMedia(QUrl::fromLocalFile("/home/root/video.mkv"));
    player->play();

}

When using " player->setMedia(QUrl::fromLocalFile("/home/root/video.mkv"));" its running very slow.

And when I use "player->setMedia(QUrl("gst-pipeline: gst-launch-1.0 playbin uri=file:/home/root/video.mkv"));"
video plays fine but its open in another window rather than the video widget.

Please help!!

Hi,

If you want to use a custom pipeline like that, you need to set a sink like shown in the setMedia documentation.
