how to build and run qml-player

[ShettyRa]

I have successfully built and run simple-player.

I would like to run the qml-player. As there is no .pro file to execute in (https://github.com/vlc-qt/examples/tree/master/qml-player) I created my own project and copied main.cpp to the sources of my project and video.qml of (https://github.com/vlc-qt/examples/tree/master/qml-player/src/qml) to main.qml of my project.

project name

video

This is how my

video.pro looks:

TEMPLATE = app
QT += qml quick
CONFIG += c++11
SOURCES += main.cpp
RESOURCES += qml.qrc

INCLUDEPATH += "C:\Users\rshe\Desktop\Qt projects\VLC-Qt_1.0.1_win64_msvc2013\include"

# Additional import path used to resolve QML modules in Qt Creator's code model
QML_IMPORT_PATH = "C:\Users\rshe\Desktop\Qt projects\VLC-Qt_1.0.1_win64_msvc2013\bin"

# Default rules for deployment.
include(deployment.pri)

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();
}

main.qml

import QtQuick 2.0
import QtQuick.Window 2.2
import VLCQt 1.0

Rectangle {
    width: 640
    height: 480
    color: "black"

    VlcVideoPlayer {
        id: vidwidget
        anchors.fill: parent
        url: "rtsp://admin:[email protected]:554/cam/realmonitor?channel=1&subtype=0&unicast=true"
    }
}

the proble is with the import VLCQt 1.0 it says qml module not found

When i build i get this three errors:

main.obj:-1: error: LNK2019: unresolved external symbol "__declspec(dllimport) bool __cdecl VlcCommon::setPluginPath(class QString const &)" (__imp_?setPluginPath@VlcCommon@@YA_NAEBVQString@@@Z) referenced in function main

main.obj:-1: error: LNK2019: unresolved external symbol "__declspec(dllimport) public: static void __cdecl VlcQmlVideoPlayer::registerPlugin(void)" (__imp_?registerPlugin@VlcQmlVideoPlayer@@SAXXZ) referenced in function main

debug\video.exe:-1: error: LNK1120: 2 unresolved externals

Can anyone help what am I missing.

Thanks in advance.

Hi,

Finally succeeded with building and running qml-player with the CmakeList.txt on Qt. I think the problem was with my compiler and setting up CMaker.

Now I have one more problem that is latency in the streaming.

In the simple-player the latency was reduced by setting the option media->setOption(":network-caching=200")

I am wondering how to set this in the qml. I have tried various options in the video.qml (ex:VlcMedia->setOption(":network-caching=300"); , VlcMedia::setOption(":network-caching=300");) but it dosent work.

Looking forward for some help

Thanks ntadej
