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

raf924

@Albus It might be a path error. Check if the file is indeed in your qrc file and check that you're using the right prefix.

Albus

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

Albus

@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
