Hey Denis, welcome to the "QtMultimedia lovers" club :) Good luck with your remarks, most likely nobody will care. It seems that the primary role of QtMultimedia is to capture input video. All the rest doesn't matter.
I've opened a number of tickets and none of them have been solved: https://bugreports.qt.io/browse/QTBUG-37004 (Feb 2014) https://bugreports.qt.io/browse/QTBUG-37005 (Feb 2014) https://bugreports.qt.io/browse/QTBUG-37882 (Mar 2014) https://bugreports.qt.io/browse/QTBUG-42034 (Oct 2014) https://bugreports.qt.io/browse/QTBUG-47284 (Jul 2015) 3 on 5 marked as P2. I would also add a recent discovery of how non-cross platform QtMultimedia is. The use case is starting a video in fullscreen on a second monitor (QtWidget way). In Linux and OSX you have to do m_videoWidget->setGeometry(rect); m_videoWidget->setFullScreen(true);and on Windows m_videoWidget->setFullScreen(true); m_videoWidget->setGeometry(rect); I didn't even open a ticket for that, cause I got tired to waste my time on this topic. ________________________________ Da: Denis Shienkov <denis.shien...@gmail.com> A: "development@qt-project.org" <development@qt-project.org> Inviato: Mercoledì 27 Aprile 2016 11:37 Oggetto: [Development] QtMultimedia && QML - hard performance regressions on Windows Hi developers. I faced with a big problem with the video playback performance, when I try to open the mp4 video file from any of QML video examples. I have a high CPU loading (~40%) and the video is freezing and jerks. But the C++ media player works satisfactory, more or less tolerably (on point 3 from the 1-5 points)... It is impossible to use at all in QML, I face more and more with the surprises of QtMultimedia, and disappointed more and more... WTF ? What sense in QtMultimedia if it does not work as expected? PS: I have created a bug: https://bugreports.qt.io/browse/QTBUG-53019 BR, Denis _______________________________________________ Development mailing list Development@qt-project.org http://lists.qt-project.org/mailman/listinfo/development _______________________________________________ Development mailing list Development@qt-project.org http://lists.qt-project.org/mailman/listinfo/development
