Description
When playing streaming videos, if the phonon SeekSlider has setTracking(true), the entire application will lock up for minutes when the slider is dragged. This does not happen when simply clicking a point on the seek slider to seek.
This only happens for streaming videos. I've tested this with youtube video streams as well as simple mp4 files uploaded to my web server.
Example application to reproduce the issue:
simpleplayer.cc
#include <QApplication> #include <phonon/mediaobject.h> #include <phonon/videowidget.h> #include <phonon/seekslider.h> #include <phonon/audiooutput.h> int main(int argc, char* argv[]) { if (argc != 2) { fprintf( stderr, "Usage: %s /path/to/file or http(s)://url\n", argv[0] ); return 1; } QApplication app(argc, argv); app.setApplicationName("Phonon Video Player"); Phonon::MediaObject* obj = new Phonon::MediaObject(); obj->setCurrentSource( QUrl(argv[1]) ); Phonon::VideoWidget* widget = new Phonon::VideoWidget(); Phonon::createPath(obj, widget); Phonon::AudioOutput* audio = new Phonon::AudioOutput(Phonon::VideoCategory); Phonon::createPath(obj, audio); Phonon::SeekSlider* slider = new Phonon::SeekSlider(); slider->setTracking(true); slider->setMediaObject(obj); widget->show(); slider->show(); obj->play(); return app.exec(); }

This also affects minitube (phonon-based youtube client), which is where I found this bug.
