使用QT的QML语言生成VLC-QT播放器

刚刚接触QT，发现它提供的QML可以像网页CSS一样制作界面，很方便。为了熟悉一下QML技术，参照VLC-QT的demo，使用其QML库编写一个简单的视频播放器。

工程很简单，直接贴代码

demo.pro

TEMPLATE = app

QT += qml quick
CONFIG += c++11

SOURCES += main.cpp

RESOURCES += qml.qrc

LIBS += -lVLCQtCore -lVLCQtQml

main.cpp

#include <QtCore/QCoreApplication>
#include <QtGui/QGuiApplication>
#include <QtQuick/QQuickView>

#include <VLCQtCore/Common.h>
#include <VLCQtQml/QmlVideoPlayer.h>

int main(int argc, char *argv[])
{
    QCoreApplication::setApplicationName("VLC-Qt QML Player");
    QCoreApplication::setAttribute(Qt::AA_X11InitThreads);

    QGuiApplication app(argc, argv);
    VlcCommon::setPluginPath(app.applicationDirPath() + "/plugins");
    VlcQmlVideoPlayer::registerPlugin();

    QQuickView quickView;
    quickView.setSource(QUrl(QStringLiteral("qrc:/qml/video.qml")));
    quickView.setResizeMode(QQuickView::SizeRootObjectToView);
    quickView.show();

    return app.exec();
}

qml.qrc

<RCC>
    <qresource prefix="/qml">
        <file>video.qml</file>
    </qresource>
</RCC>

video.qml

import VLCQt 1.0
import QtQuick.Layouts 1.0

Rectangle {
    width: 1020
    height: 620
    color: "yellow"

    GridLayout{
        id:vo
        columns: 2
        rows:2
        anchors.fill: parent
        Rectangle {
            id:r1
            color: "green"
            Layout.fillWidth: true
            Layout.fillHeight: true
            VlcVideoPlayer {
                id: vidwidget1
                anchors.fill: parent
                url: "rtsp://192.168.1.3:8554/xiao.mkv"
            }
        }

        Rectangle {
            id:r2
            color: "green"
            Layout.fillWidth: true
            Layout.fillHeight: true
            VlcVideoPlayer {
                id: vidwidget2
                anchors.fill: parent
                url: "rtsp://192.168.1.3:8554/2.mkv"
            }
        }

        Rectangle {
            id:r3
            color: "green"
            Layout.fillWidth: true
            Layout.fillHeight: true
            VlcVideoPlayer {
                id: vidwidget3
                anchors.fill: parent
                url: "rtsp://192.168.1.3:8554/3.mkv"
            }
        }

        Rectangle {
            id:r4
            color: "green"
            Layout.fillWidth: true
            Layout.fillHeight: true
            VlcVideoPlayer {
                id: vidwidget4
                anchors.fill: parent
                url: "rtsp://192.168.1.3:8554/4.mkv"
            }
        }

    }

}

效果

有个大问题，这样编译出来的程序，在QT run情况下能够正常运行。但是直接打开exe文件会提示QT5NetWork.dll找不到程序接入点，好奇怪呀，不知道哪里的原因。
