qt - 音频Qml失败

Question

我正在尝试将背景音乐添加到小型应用程序中。我正在使用Window7和MinGW，但出现此错误:

ASSERT: "!url.isRelative() && (QQmlFile::urlToLocalFileOrQrc(url).isEmpty() || !QDir::isRelativePath(QQmlFile::urlToLocalFileOrQrc(url)))" in file qml\qqmltypeloader.cpp, line 1639 Invalid parameter passed to C runtime function. Invalid parameter passed to C runtime function.

这是代码:

import QtQuick 2.0
import QtQuick.Controls 1.1
import QtQuick.Controls.Styles 1.1
import QtMultimedia 5.8

Rectangle {
    id: main
    width: 600
    height: 400
    state: "mainMenu"
    property int margePixel: 30
    property int tailleInfoJeux: 200

    Image {
        id: background
        source:"qrc:/images/mainbkg"
        anchors.fill: parent
        fillMode: Image.PreserveAspectCrop
        sourceSize.height: 800
    }

    MediaPlayer{
        id: musicBkg
        source: "file:///Users/COMPUTER/Documents/candycrush/candy-crush-like-master/sound/bkg1.wav"
        autoLoad: true
        autoPlay: false
        volume: 1.0
        loops: Audio.Infinite

        Component.onCompleted: {
            //console.log(source==Qt.resolvedUrl("file:///Users/COMPUTER/Documents/candycrush/candy-crush-like-master/sound/Kalimba.mp3"))
            console.log(musicBkg.supportedAudioRoles())
        }
    }
}

这是.pro文件

试试这个，

source: "file:///c:\Users\COMPUTER\Documents\candycrush\candy-crush-like-master\sound\bkg1.wav"
