Enable Codecs in QtWebEngine using qmake on Mac

Nineswiss

I am trying to work out how to set "use_proprietary_codecs" within my QtQuick app. I have got QtWebEngine working but need to be able to play mp4 h.264 etc (and widevine but I can work on that next).
My code so far:
.pro

QT += quick
QT += webenginequick
# You can make your code fail to compile if it uses deprecated APIs.
# In order to do so, uncomment the following line.
#DEFINES += QT_DISABLE_DEPRECATED_BEFORE=0x060000    # disables all the APIs deprecated before Qt 6.0.0

SOURCES += \
        main.cpp

RESOURCES += qml.qrc

# Additional import path used to resolve QML modules in Qt Creator's code model
QML_IMPORT_PATH =

# Additional import path used to resolve QML modules just for Qt Quick Designer
QML_DESIGNER_IMPORT_PATH =



# Default rules for deployment.
qnx: target.path = /tmp/$${TARGET}/bin
else: unix:!android: target.path = /opt/$${TARGET}/bin
!isEmpty(target.path): INSTALLS += target

main.cpp

#include <QGuiApplication>
#include <QQmlApplicationEngine>
#include <QtWebEngineQuick>


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);
QtWebEngineQuick::initialize();
    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 QtWebEngine

Window {
        width: 1024
        height: 750
        visible: true

        WebEngineView {
            id: webViewer
            width: parent.width
            height: parent.height-60
            y: 60
            url: "https://dribbble.com"
        }
}

Anyone able to help?

I worked it out.
I installed qt via brew and added
to main.cpp

qputenv("--webEngineArgs","--webengine-proprietary-codecs");
