widget overlaying autovidesink

[Nikola]

Thank you for your response.

I didn't know this is possibility in QT.

Only thing which is confusing now is how to implement this.
I have looked at examples around but I didn't get the general idea.

Currently I am showing video by using following code:

----

void GstPlayer::playRTP(int port) {


    m_pipeline = QGst::Pipeline::create();



    QString rtpPipeDescription01 = QString("udpsrc port=\"%1\" ! "

                                "application/x-rtp,
encoding-name=JPEG,payload=26 ! "

                                "rtpjpegdepay ! "

                                "jpegdec ! "

                                "autovideosink").arg(port);

    try {

        m_pipeline =
QGst::Parse::launch(rtpPipeDescription01).dynamicCast<QGst::Pipeline>();

    } catch (const QGlib::Error & error) {

        qCritical() << error;

        qFatal("One or more elements are missing");

    }

    watchPipeline(m_pipeline);

    m_pipeline->setState(QGst::StatePlaying);

}

First this class would be instantiated.
On the qtdesigner I would add widget and promote it to this class, and then
play would be called with designated port.
I have tried to use several sinks instead of autovideosink: qtvideosink",
"qtglvideosink" , "qwidgetvideosink" (or "qt5videosink", "qt5glvideosink"
and "qwidget5videosink" in Qt5) but all are reported as not present
(example: "no element \"qwidget5videosink\"")

Found them on this page:
https://gstreamer.freedesktop.org/data/doc/gstreamer/head/qt-gstreamer/html/classQGst_1_1Ui_1_1VideoWidget.html

 Should I use it in different way?


Kind regards,
Nikola.
