Qt Multimedia issue on Qt 5.7



  • I installed Qt 5.7 on an Ubuntu 16.04 operating system using the online installer. Anytime i attempt to launch any example that employs the use of Qt Multimedia i get the following errors for

     defaultServiceProvider::requestService(): no service found for - "org.qt-project.qt.mediaplayer"
    qml: error with audio 5
    No Input Settings found, keyboard and mouse events won't be handled
    

    Please help

    Hi,

    Do you have GStreamer installed ? If so, what version is it ?



  • Thanks for your concern yes I do have GStreamer Installed and its version 1.0

    Do you also have the plugin packages installed ?



  • I have the plugin packages installed

    Then start your application with the QT_DEBUG_PLUGINS environment variable set to 1 to see what happens with your plugin.

    You can do in Qt Creator's Run part of the Project panel.

  • just found the solution
    Qt 5.7 on ubuntu requires GStreamer version 0.1 and all its plugins. not version 1.0. Sounds funny, but it works
    Much Thanks to SGaist for the concerns


  • Lifetime Qt Champion

    You're welcome !

    You also have the alternative of building the GStreamer plugin using your installed 1.0 version.



  • Ok. I'll also look into that
    Much Regards
