Hi there.

height : 600
//source: "video.avi"
source:"asf_to_mpeg-1.mpeg"

 MouseArea {
     anchors.fill: parent
     onClicked: {
         video.play()
     }
 }

 focus: true
 Keys.onSpacePressed: video.paused = !video.paused
 Keys.onLeftPressed: video.position -= 5000
 Keys.onRightPressed: video.position += 5000

}
