QML Audio is not able to access mp3 file in qrc (windows)

[Albus]

@raf924 Thanks for your advice. I am sure the path is correct, since it works normally in other 3 platforms.

@SGaist Do you mean "dsengine.dll"? I do have this DirectShow plugin installed.
And this dll is not loaded while running my program.

[SGaist]

Then try to move it of the multimedia plugin folder to ensure that the WMF plugin gets loaded

[Albus]

@SGaist I renamed these dll, nothing special happened, the program ran normally (but when playing the mp3 file, the error was : MediaPlayer fail to load source).

Actually, early before when I first tried to run my program, it failed to load every dll it needed, thus I had to copy all dll to have a fast try. But WMF and DS dlls are never asked.

[SGaist]

Starting your application with QT_DEBUG_PLUGINS set to 1 will show you what gets loaded

[Albus]

@SGaist Thanks for the hint. I searched the entire output, not wmf, not dsengine is found.

[SGaist]

Which are loaded ?

[SGaist]

What code are you using to play that audio file ?

[Albus]

@SGaist here is my code :

MediaPlayer {
    id: music
    autoPlay: true
    source: "qrc:///musics/musics/Highway_Wildflowers.mp3"
    loops: Audio.Infinite
    volume: 0.6 * CallBacks.getFastAudioSettings()[1]
}

[SGaist]

Then it probably is using the audio plugin which I'm not sure at all is supporting qrc
