[Solved][QML + Qt5]Video

AquilaDev

Hello!
I'm on Linux, and i've some troubles with QML and Multimedia module:
I want to use a video as background in a QQuickView.

@import QtQuick 2.0
import QtMultimedia 5.0

Rectangle {
width: 300
height: 300
color: "black"

 MediaPlayer {
     id: mediaPlayer
     source: "movie.avi"
     autoPlay: true
 }

 VideoOutput {
     id: video
     anchors.fill: parent
     source: mediaPlayer
 }

}@

And this is what i saw in Qt doc, but i get this error:
@GStreamer; Unable to play - ""
Error: "No URI set" @

I also try the qml video example (which looks similar) but i didn't get any error with it.
( http://qt-project.org/doc/qt-5.1/qtmultimedia/video-qmlvideo.html )

Hope someone could help me..
(In 2011 someone report this error as a bug in Qt: http://lists.qt.nokia.com/public/qt-mobility-feedback/2011-March/000977.html)

No idea ?

I was able to run this code on Ubuntu 12.04 with gstreamer 0.10.22 and Qt 5.1.
Created project as both a QtQuick 2 application and as a QtQuick 2 UI application.
When I moved the avi file out, application directory, I got the corect diagnostic - "GStreamer; Unable to play -" and the path to the avi file.

Ok. That's only when i import a qml file from a qrc.. but when i'm using QUrl::fromLocalFile() it works...

I had the same problem, could you advice on the solution?
my code work in Qt Quick UI but not in Qt Quick Application.

I could run MediaPlayer source, exact duplicate to your code
on Qt Quick UI but on Qt Quick Application.

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

QGuiApplication app(argc,argv);

QQmlApplicationEngine engine;
engine.load(Qurl(QStringLiteral("qrc:///main.qml")));
return app.exec();

}
