Hi all,
Im using Gstreamer (1.16.2) and QT (5.14.2). Im using qmlglsink to display
webrtc video stream.
When I try to stop pipeline with qmlglsink QT background tasks are blocked
(timers, callbacks...).
What Im doing basically boils down to this example:
https://github.com/GStreamer/gst-plugins-good/blob/master/tests/examples/qt/qmlsink/main.cppplus I added to timers between lines 72 and 74:
* QTimer * timer = new QTimer();
timer->setSingleShot(true);
QObject::connect(timer, &QTimer::timeout, [] () {
qDebug() << ">>Stop pipeline<<" << endl;
gst_element_set_state (pipeline, GST_STATE_PAUSED);
gst_element_set_state (pipeline, GST_STATE_NULL);
});
timer->start(10000); //in ms
QTimer * timer1 = new QTimer();
QObject::connect(timer1, &QTimer::timeout, [] () {
qDebug() << ">>Alive!!!<<" << endl;
});
timer1->start(1000); //in ms
*
first timer will stop pipeline after 10s and second one just prints message.
After first timer stops pipeline there is no more printouts from second
timer.
I guess that Im not stopping pipeline correctly? what is or is there a
correct way to stop pipeline with qmlglsink that uses GstGLVideoItem
element.
Br,
Dejan
