    Okay here's the deal. I am on Ubuntu 14.04 LTS, have installed Qt 5.6, qtmultimedia5-dev, gstreamer0.10 (and 1.0), and libqtgstreamer-dev.

    I am STILL getting this error when I try to use a QAudioDecoder:

    defaultServiceProvider::requestService(): no service found for - "org.qt-project.qt.audiodecode"

    What am I missing?

      Hi and welcome to devnet,

      Something's not clear: did you install Qt using the online installer, Ubuntu's software center or both ?

        I used the online installer originally with 5.5, and then recently used the maintenance tool to remove 5.5 and install 5.6. All of that before doing anything with multimedia or gstreamer.

          What about qtmultimedia5-dev that you mention in your original post ?

            That one did not come with my Qt installation, so that was a 'sudo apt-get install...' along with the other gstreamer packages.

              @Alex-Court It's also worth noting here that I could not add 'QT += multimedia' to the project file until after I did the installation of qtmultimedia5-dev.

                It looks like you're using the Ubuntu packaged Qt and not the one you installed using the installer.
                You should check the Kit in QtCreator you're using.
