    I read that QtMultimedia (I use it from QtQuick)
    can access the system codecs using GStreamer on Linux.

    I am on Fedora and installed RPMFusion and installed

    sudo dnf install gstreamer* phonon* x26*
    

    Yet it does not support the codecs that are supported by gstreamer.
    What package exactly is required?

      Hi,

      You need the GStreamer plugin packages which your expression may have installed but it's worth checking.

          What codec is not supported ?
          Can you read the file from GStreamer directly ?

            I am on Fedora Silverblue (thus if you unlock your / you can install stuff with dnf but it gets reset on reboot).

            Once I installed kinda ALL of rpmfusion-free and rpmfusion-nonfree and it worked
            (the codec is not the problem!),
            after reboot the / is reset and I try to find what packages did make it work.
            It seems its not one of the ones in the glob expressions.
            So what else does Qt Multimedia need Phonon? (installed).

              AFAIK, just GStreamer. If anything else that would be distribution specific and should be automatically provided as a dependency of the corresponding package.
