Qml video metaData returns undefined values

[paghsa]

hi guys
lets take a look at this code

        Video {
            id: video
            anchors.fill: parent
            autoPlay: true
            source: vidPath !== "" ? ("file:" +  vidPath) : ""
            focus: true
            loops: MediaPlayer.Infinite

            MouseArea{
                anchors.fill: parent
                hoverEnabled: true
                onEntered: {
                    console.log(video.metaData.videoBitRate)
                    console.log(video.metaData.size)
                    console.log(video.metaData.videoFrameRate)
                    console.log(video.metaData.duration)
                }
            }
        }

the problem that i have no idea to figure out is all console.log print undefined
any help will be appreciate
