Hi, Im playing a mp3 file using QMediaPlayer as a background music for my program.

I generated a dump from user system that have this problem and here is some part of it:

its says that the problem is coming from SMM_MP4Demuxer Module, by looking at its name I think its something that coming from QMediaPlayer...
So I wonder how can I manage situation like this..? can I still some how play the sound? or at least can I check if the user system support playing the sound and then play it? and if not just skip it?
here is the code

QMediaPlaylist* playlist = new QMediaPlaylist(this);
playlist->addMedia(QUrl("qrc:/background_sound.mp3"));
playlist->setPlaybackMode(QMediaPlaylist::Loop);

background_sound = new QMediaPlayer(this);
background_sound->setPlaylist(playlist);
background_sound->setVolume(70);
connect(background_sound, &QMediaPlayer::mediaStatusChanged, this, [&](QMediaPlayer::MediaStatus status) {
    if (background_sound->error() == QMediaPlayer::NoError) {
        if (status == QMediaPlayer::LoadedMedia)
            background_sound->play();
    }
});

if I run the program on for example a sandbox that don't have needed codecs, it will just print errors over and over again infinitely... there is no stop to it... (no crash though)

so I wonder how can I make sure if the system actually support playing the sound... and if not try not to play at all...
