Question

我是QT C ++的新手，我正在尝试使用Qmediaplayer库实现一个代码来传输视频。

这是我的代码：

    #include "dialog.h"
    #include <QApplication>
    #include <QMediaPlayer>
    #include <QVideoWidget>
    #include <QDebug>

    int main(int argc, char *argv[])
    {
        QApplication a(argc, argv);

        QMediaPlayer* player = new QMediaPlayer;
        QVideoWidget* vw = new QVideoWidget;

        player->setVideoOutput(vw);
        player->setMedia(QUrl::fromLocalFile("/media/dimo/New Volume/Media/Video/anime/[AnyAnime.com] Boku no Hero Academia - Ova 02 [LQ].mp4"));
        vw->setGeometry(100,100,300,400);
        vw->show();
        player->play();
        qDebug() <<player->state();

        return a.exec();
    }

这是专业档案：

    QT       += core gui multimedia multimediawidgets

    greaterThan(QT_MAJOR_VERSION, 4): QT += widgets

    TARGET = videoplayer
    TEMPLATE = app

    # The following define makes your compiler emit warnings if you use
    # any feature of Qt which as been marked as deprecated (the exact warnings
    # depend on your compiler). Please consult the documentation of the
    # deprecated API in order to know how to port your code away from it.
    DEFINES += QT_DEPRECATED_WARNINGS

    # You can also make your code fail to compile if you use deprecated APIs.
    # In order to do so, uncomment the following line.
    # You can also select to disable deprecated APIs only up to a certain version of Qt.
    #DEFINES += QT_DISABLE_DEPRECATED_BEFORE=0x060000    # disables all the APIs deprecated before Qt 6.0.0


    SOURCES += \
            main.cpp \
            dialog.cpp

    HEADERS += \
            dialog.h

    FORMS += \
            dialog.ui

但它给了我这个错误：：-1：错误：找不到-lpulse-mainloop-glib ：-1：错误：找不到-lpulse ：-1：错误：collect2：错误：ld返回1退出状态

在Qt Creator中找不到库
