I’m trying to create simple video player with QML. I have QtSdk installed and QtMobility compiled and installed from source. Then I put this simple video playing code to main qml file:

import QtQuick 1.0
import QtMultimediaKit 1.1

Item{
    width: 400; height: 300
    Video {
        id: video
        source: "d:/Projects/Serenity - HD DVD Trailer.mp4"
        anchors.fill: parent
        MouseArea {
            anchors.fill: parent
            onClicked: {
                video.play()
            }
        }
    }
}

After compiling and running application, video plays choppy and on exiting application it puts this in log:

2011-06-07 11:13:44.055 video-player[323:903] *** __NSAutoreleaseNoPool(): Object 0x10225ea60 of class NSCFNumber autoreleased with no pool in place - just leaking

If any way to make it playing smoothly and to prevent memory?
