QML module not found (VLCQt) in Qt_5_12_2_MSVC2015_64bit Windows 10 and VlcQmlVideoPlayer is deprecated

[inejose]

Hi,

I am trying to integrate this VLCQt QML project but I am not able to recognize the library.

In the main.cpp I get the following warning on the "VlcQmlVideoPlayer::registerPlugin();":
VlcQmlVideoPlayer is deprecated

In the qml:
import VLCQt 1.1 //QML module not found (VLCQt)

Compiler and Qt:
Qt_5_12_2_MSVC2015_64bit

I downloaded VLC-Qt_1.1.0_win64_msvc2015 binaries and copied the content to my src/lib/vlcqt folder.

I also added to my \build-hmi-Desktop_Qt_5_12_2_MSVC2015_64bit-Debug\debug folder to be able to debug.

Please, has anyone managed to integrate the libraries without compiling the sources? I would be very grateful for an answer or a clear example, we have planned a project thinking about this utility and we have been several days without being able to advance, we do not have much experience integrating external libraries.

Thank you very much.

These are my source files:

    VlcCommon::setPluginPath(app.applicationDirPath() + "/plugins");
    VlcQmlVideoPlayer::registerPlugin();

    return app.exec();
}

Getting the same issues on Ubuntu 18.04. Build VLC-QT from source and installed to /usr/local/qml.

main.cpp

#include <QGuiApplication>
#include <QQmlApplicationEngine>

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

int main(int argc, char *argv[])
{
#if QT_VERSION < QT_VERSION_CHECK(6, 0, 0)
    QCoreApplication::setAttribute(Qt::AA_EnableHighDpiScaling);
#endif

    QGuiApplication app(argc, argv);

    QQmlApplicationEngine engine;
    const QUrl url(QStringLiteral("qrc:/main.qml"));
    QObject::connect(&engine, &QQmlApplicationEngine::objectCreated,
                     &app, [url](QObject *obj, const QUrl &objUrl) {
        if (!obj && url == objUrl)
            QCoreApplication::exit(-1);
    }, Qt::QueuedConnection);
    engine.load(url);

    return app.exec();
}

main.qml

import QtQuick 2.15
import QtQuick.Window 2.15
import VLCQt 1.1

Window {
    width: 1000
    height: 480
